nice the nice get their home phone there in baby's shuttle stops oldest on d w. the home has a color that is green. one german research team is convinced that algy can help solve some of humanities. greatest problems around the globe. biologists are hunting for micro organisms with extraordinary abilities, like limes to creating l g, which might one day generate climate neutral summit for 10 to verify percent of blood block as far as c o 2, come some construction to go from the concrete production. now here's a possible concrete substitute, that's the exact opposite. it doesn't produce c o 2 to absorb it absorbs itself for

over a year. we've accompanied researchers from kaiser's loud tones, university of applied sciences to the depth of a spanish case where life on mars is being stimulated here on earth or in space. algae could be the key. i didn't come up 1st, go for a 1st name and i'll get those can take in waste materials and wasteful to then extract nutrients from as often with very different light and they can also produce oxygen. so as i can find the c o 2 we exile, creating oxygen and food. same time on this. okay? probably amongst the best organisms for producing food. but i don't know the

in an expedition in northern spain, an hours drive from build out these researchers led by a biologist, me see a lack of toast. are exploring a cave in hopes of discovering new species of algae and furthering their research on known once. they're not exactly sure what awaits them. there are almost 300 caves in this valley alone. and some 4000 in all of count abriya. one caved in particular is of special interest to the german expedition team. the what they discover here is mind blowing. misha, yeah, lack of toast, finds organisms that bear witness to the very origins of life on earth, the god of embodied steve, i've just found

a huge patch with one of the oldest son in the back of the scenery, aware, aware of the big catch. incredible things, i've never seen anything like that. it's quite incredible. i'm. it's a loss to what we fidget closet, right. what's left him speechless is how these bacteria known colloquially as blue green algae can survive with so little light, the noise on one hand, we really want to discover the isolate new sign and bacteria and use them for quite a technological applications. at the same time thought when we have in such a marvelous habitat, the 1st question is naturally, how would they survive it? so that's what we're doing is we're measuring photo synthesis with this device. the we're also seeing to what extent they've adapted to the light and how they utilize the unofficial parts for the algae researchers, this category in caves is

a godsend. the only person might just the a mazda you looking rock face. but for the biologist, it's a window into a fascinating world, an extraordinary multi generational colony. since you do some shopping, you can see these colorful surface here. these fluffy little gray green pads doesn't get these assigned or bacteria. and so with these yellow ones here, these pink jelly light clouds, this striking the optic, that's the particular sy entered bacteria and we're off the globe back to clear. we'll talk each one of the oldest leading cyan or bacteria. and so it's a very basic primitive, cyan and bacterium that's leaving here alongside more modern spacing is a bit of a voltage differently. they're all living here in the colon, including this is like the misha locker towson patrick young. are thrilled with the wealth of research material they found and

excited about the new questions that arise from it the best we know that they can survive without much light spots. but we don't know exactly what the lower limit t's is. also the question of how exactly these works in the low line situation. we've been counted deeper inside the cave, so i entered bacteria population. there is different kinds of if we found different species, a certain process is a different to you and are either so the allergy here is quite tough, august responders, and i can yes, they can photo synthesizing the dog. we've moved even further into the cave and despite the total darkness find species of algae living here to feel comfortable enough in the town. and there's only a 100000 for the light from above can reach them as a volume. allowances in the dogs is a little they simply structure that physiology about that photo synthesis and the

thing so they can use most, i mean the visible light spectrum. but 1st industry, we switch the exciting of this and they may also be able to draw from further along the range of light and the random non or in the fall. right. and for the so got was looking. couldn't you understand that it was spanish biologist, antonio gibson, who 1st drew his german colleagues attention to the case and sent them samples. it was the beginning of a great friendship between the spanish and german algae researchers assigned to the he didn't have it, even gumble a, you'll get tons of a new field of research. i find it very interesting in terms of the production and research of useful substances. of materials, so it is not just the biological aspect which is already fascinating it and that's, but it's also the practical application or something. you know, that really got to him. but i think in that regard and do the patrick and michael's ideas are in line with us a and i can other what? so if you think we're happy to continue supporting them here and we're looking forward to working even more closely with the program most. but it's not it,

is that a push it till the here instead of you many that as the spanish biologist works for a company that wants to model mars missions here, they've set up a space station of sorts. deep within the cave. the algae research conducted by the german team could also be interesting permissions into space escaping time to take on those today that and if you had to get them to lines perfectly with our original plan to draw on the potentially lease unexplored micro organisms like gap them all apparently capable of producing substances that have not yet been recess. antibiotics, for instance, at the moment. so these organizations are in fish competition with each other. so they put to you santibanez things sort of, i need most of it didn't know, not incompetent yet. and today you was interested in it on and see if you think like produce new truths instead of as food for other organisms. so they could serve as food for us. digital simply deal could all be possible. but english what,

but understand you meant that the on both of us, it a change of scene. we had to the laboratory, a kaiser's low tones, university of applied sciences. the permits ends campus is home to the worlds the largest collection of terrestrial fiano bacteria, algae that live on the land, not in water. for study purposes, there being cultivated and liquid, none the less. over $350.00 species from all over the world can be found here. gums of march this year or the i'm for example here, your advice and i think the cost of the options for me, i'm talking to the union sent you the how guys here we've isolated mike or call us for it. like how go from very whole this of regions and a completely new algo we've identified, even from sol involved and the optic of the all can attend the, to the candy. what does that do? the, the kind of you have to what has a smaller red and a quite unusual that we don't know why it's the guy just died. researchers started

the collection back in the 1950s, the algae from the spanish cave, or the latest edition, and could one day help us face the climate crisis. doesn't face it, the baby could somebody be covering it? there were some of that kind of caught up in ice, for example. cool how they behave like rebuilding carl. i'm kind of producing a sort of troy piece kind of times he is one of our new projects here is to see whether we use this as a submitted substitution as a cement, as a can be crossed. and um, yeah, 2 bucks. that's a menu of all the samples we collected are in here. do you think of some of them the german researchers are traveling the world on the hunt for new species of algae . they most recently spend 4 weeks in the out of comma desert and she'll a while the whole spine of the cactus here, the of the trend to police samples. that's a special type of liking that grows on the tips of the tax id number is next period . assets are extreme locations. it's very hard and this little volta venue of the

organisms can survive. the i can also withstand very high temperatures in by technological reactors, for example, on somebody 0 with templates one or one that's number one. and number 2 in extreme habits that site back to organs, new always find organisms can do something very special from such as producing special active substances except for adopting specific new metabolic pathways. stuff like the big armstrong, some algy enter into symbiosis with fund guy in order to survive and extreme places forming. lincoln's patrick young, found such l. g, fungus, symbiosis, and the out of comma. the fun. this becomes a kind of sun shade for the algae. that is on the, on the, among other things. it also, it provides you the protection against the hush radiation one finds in the to come and visit the l. b a not mobile. they trapped in a stationary position and somehow have to protect themselves from the sun's rays,

which they can't avoid, fits with the like. and like these ones that task falls to the funds will talk to them as they produce a certain pigments in the case of these fisheries. those pigments that green is yellow in appearance or another key feature. the colonies survives on very little water. these are all properties that could come in very handy, say in the development of new products to reconvene. how can we turn organic waste into plastic abundance? early march 2020 to the official launch of a research project called the waste to value. the vision at some point l g will be grown directly on building facades and residents could benefit from the harvest. if bio plastics were able to thrive on such besides, it could also lead to growth and regional economies. all thanks to algae, greene fuels could also be created using the same method research

as being funded by the german federal state of rhineland, polite, nate, they see it as an investment in the future and then just perform that. and those kind of heard of that on the state level, many companies would benefit from becoming a little less dependent on energy supply as a product. that's a significant consideration these days are no, we'd also be making a contribution to climate protection from here in rhineland. blessone, it's about since i was kind of kind of to help the german federal ministry of education and research is also funding the project. they've granted 8000000 euros for the 1st 3 years. several partners are working with the team from parents sense his shots, unknown to get caught out with currently enjoying an initial spark of interest move just hoping to progress as far as possible with the companies i need, ultimately implementing some of the only thing is we've been we're searching for yes. so on this one, got it under forced tom. yeah. mine's of yes. wonderful. just great. does the 2

researchers are unpacking a new piece of equipment. a photo bio reactor that says it will allow them to grow algae that normally live on land in liquid and thereby control the way they reproduce. as the thing on some documents on these items, the problem as well documents, i think ro, an a controlled amount of stuff. i don't know, log scale. this isn't that we can then control that grows here. and it kind of pre culture and transfer them into the loan to react with exact tooling. and soon analogy that's popular with biologists will be growing in this reactor as a buyer's peer. so these, for example, is the elaborate people to buy a technologist working without getting with the systemic assistance. it's used quite frequently and curbside daily and conditions like this. but the of the month, 2 of us, what you see here, for example, of the terrestrial, i'll give you a right to know stuff in school. the multicellular and threat, like the little met syndic is feed them into. you can see immediately they tend to

clump together when you have to prevent that. what with this mixing process? yeah. when we're curious to see how we sound, be close and then we have no experience with it yet. the do the other than vix this . so i'm not kind of follow that you haven't tried yet. yeah. zoom the comp time. is it? so we'll take a doing here. we don't even know yet. we carry out as much fun. you want us to inspire, then we can move. the reactor is an important intermediate step towards producing larger quantities of bio plastics or climate friendly summit one day exist. and so this isn't close that window seat up is a big difference between trying to force nature into the lab. that's to say, conducting experiments on a small lavar tree scale thing and being able to think on a launch or industrial scale and couldn't that's a whole other botox isn't. it extends out on us not 100 percent. that took the longest the least connection. that's for the modules the size of a window,

the researchers have already commissioned them. the idea is to grow algae on facade inside these photo by a reactors. if it works, the process could save a lot of waste in c o 2. there are other benefits as well. some algy produced natural dies. some could end up on our plates a lot to me on the now we have solar systems on the roof and future. we could also cover the east and west facade through these al, give reactors, i then even collect this would regularly come by to office the for the whole we to all of a star cells food order. so say the essence cause noises. a lot of research is still required though. space to the new research reactor will soon be housed in this former changing room. i understand. we'll be back for a visit once the researchers have filled it with algae. for now, it's back to spain. misha locker towson, his spanish colleague, have to send

a deep into the cave and reached the mar station. the aim here is to replicate living conditions on the red planet. as realistically as possible, the one day l g might be able to help space pioneers survive on mars. the minds can cut about 10 minutes of your upside stuff or upsets or to sign effects. here you can say can waste materials and waste water and extract the nutrients from having a very different lights, like we have a um they then compare to you. so i'll just put it in as i can find the c o 2 weeks hail to fit, creating oxygen and food at the same time by on. no, no, i'm going to put up some of the old probably among the best organisms for producing food in the space and can embed. now let's see what the test station in the spanish cave. the company hopes to approximate life on mars. even if some martian conditions are impossible to reproduce,

we cannot say of abuse because i'd be willing to take a look on the, on the, on the boss selling products. okay. the, the young thing would be actually to be a much about taking advantage. now we have another mass, wherever brand new, we come made mistakes. diana and i can help us to have him play the bid of some of the questions. then we'd like to help us to somebody up there. i'm gonna let me buy all a g as an important area of research for this 1st bound, myers expedition and algae could play a key role here to the main lines of investigation with office headquarters, engineering, of course, on the compiler that you everything when it comes to the protocol for the is that too far live on so long? i've been new teens and how come we want to be society and we need to research a pc and a ton of ours. you know, so everything that i've been to and should have on techniques and your team for

these young a food unity. so all that stuff is mostly in place to put on the german researchers can hardly wait to find out more about the various ancient algae species they've discovered in the case they're collecting samples back at their home laboratory impairments ends. they'll place them under the microscope for a closer look. and then uh, and then the one thing that will analyze the samples and then definitely take another look at that cheat. so we want to really see it's not just one species or 2 or 3 that are probably many, many different organisms living together here, a little microcosm, so to speak, and one of the host to come when that's what we want to find out the need shuttle to do that, when we're carrying out genetic analysis to determine which organisms are living together here on this fall back to pair ms. hence, the new research reactor is full of life in the form of ality. now it's hoped they

will multiply and the researchers can grow various algae and the reactor unimportant steps in cultivating alternatives to environmentally harmful plastic. because of 4 times on this, one of the crate advantage of the southeast diploma stock is that it can produce by protesting. so that means if you give it sugar, so you should think given the additional carbon sources consent stops to produce material gas a time. that's the basic building block for a really great fire plastic. that's called p h b for chauffeur's fuel plastic, that's most by compatible. i'm fine to grind or combustible. is it used to sutures in medicine for example, see about it's prevented from somebody to, to, to need to buy them to, to our bodies would probably cope much better with organic plastic in our food than with conventional plastic. under the microscope, you can see the bio plastic that the allergy forms. as white dots. there's going to

be more more time on this, but what's a problem at the moment? going bike level w, w. s dot edu is the we ingest, around 100 micro particles of mancha plastics with each meal testicle. that's the equivalent to the 2000 pulse because a week or 5 grams each week. um, that's the equivalent to the credit card division in minor to take that means the don't have rich that everyone in the world every week is each a credit card with a plastic and it could be cards a cluster eventually the laboratories research reactors will be replaced with these window modules, then everyone can watch algae at work in their own window. the americans 1st, this is cooling called, so to speak and, you know, but some of these, these are much less voltage. just an aerosol sprite, 90 percent less of all times. they have pets of gas exchange, the easier to harvest. and so that is what this is on newest model for going sign it back to here in the future in sort of 2 out of 10 knots. it's just dies. could

be grown here in these beside windows or cosmetics, or even food. this machine has a cussing somebody out even in china. no. yes. as a traditional new yes dish, for instance. that's the most talk flag in the form of i'll give it's collected from the test that we can grow it here under these conditions and then set it where it's like comp being crowded in the of a liquid process on each box. and then it will take some time before the 1st products made impairments ends come onto the market. we still have a few years to wait to for the 1st organic concrete produced with spanish cave algae use of trucks. this block is now 1st prototype. i'm about to, to you, we introduce to cyan and bacteria strain into the concrete in process of it's not yet one from the case. the, this is a bar and treat strain energy about how we carry down south those preliminary tests with a test to see whether this process works with cyan or bacteria. we're talking about

in the loan to him. we want to work with the cyan or bacteria from the case, but since they calcified naturally, we can then use the process for concrete productions in this way. the system can be another 2 to 4 years before we've optimized decision on the door. just too soon to tell. yes, we're on the right track. in our fight, in the eiffel region, a metal construction company is building for large bio reactors. the window modules will be 2 meters 40 high one meter 42 across. now the questions which one goes to the bulk and then which at the top of this one here, and that there is one of the research here. michelle lack of toast is seeing the modules for the 1st time today. of course, audio bennett is tight. amazing. we need to really think, okay, that should defend roughly key, but then you see how big it is. in reality,

i mentioned that we've never had before. and that's also really important because of, we're always working on a bar to scale news. 100 milliliters by maybe 10 liters is the largest size, but see in our 100 leads to prove us a whole lot of a story that we're really getting into it now on the ground. this guy. okay, let me push the going. it's going to include in the state of the state of rhode island to pull out native, picking up the bill around $80000.00 euros to produce 4 modules. the reactors can be set up in a laboratory. however, the researchers can also hang them on building facades and grow algae. there is nothing can put them right. and that's as far as leaving the water comes in from the top. so it just makes sense and then spreads through the whole entire area on the when it drips down, it's fed out going to the bottom and circulates back to the top of the down whole slide to see if we get them for the small metal and steel construction company,

it was quite an order, not least because they had to procure acid resistance, stainless steel, for the ocean when i read the cool to attend isn't so bio reactive it 1st i wanted what it was. so is it something atomic? that's what it sounds like it 1st go. in retrospect. so it makes a lot of similes thing's old. i must say, i find what they doing. they have very interesting discuss. i'm a fan of the project, something for you. i'm gonna find it to prevent the algae in the module from getting too much light for dying from overheating. sun protection is built in the fact that it never the sucking so high inside of the react to muscle to horses. good, because otherwise the l you would get to halt as well. and di, um yeah, that's why we've changed it from the sun 1st from above. and then again, from the site, the event will hang cold by the pounds and the cons that will surprise to a provide even more shade for the result. is this under course of this type of, especially if we're going back to the l g and the reactors will soon be producing

file, plastic and absorbing c o 2 from the air. they'll be hung on an actual facade in stuttgart. for research purposes. michelle lack of toes is convinced elegy reactors like this, have a great future ahead of them and will one day be part of every city escape. this is this moment tom view like photo more tight and then the way we have photos of all tags were in the 1970s. we've developed it. so just being a new craft quickly we can actually get into use of i'm on houses in houses. ultimately, that's up to the politicians originally intended us to put it if they subsidize, it doesn't feel good will happen very quickly without the size of the world of cost . well, it's certainly part of the mix forced time from feeling for now the l. g researchers from parents and still have a lot of exploring to do in every corner of the planet, the,

the eco ask for it in volume and to come sedation, the superstition in gonna many people believe that the weather is influenced by spirit. now especially trained use for gates on working with indigenous communities to challenge traditional local east coast to africa in 30 minutes, d w over half a 1000000 dead in the t. great warranty, c o, p s, fueled and intensified by social media. what role to facebook's algorithms
