the what can we do? carry on and some last, a nice the nice you get their hosting for america. and babies shuttle task oldest. good on d, w. the whole has a color and it's 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 energy, which might one day generate climate neutral cement. from 10 to 5 percent of blood black as far as seo to come some construction to the concrete production. yeah. 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 low towns, university of applied sciences to the depths of a spanish case where life on mars is being stimulated here on earth or in space. algae could be the key, i can come up 1st, go for a 1st name, and i'll give you all can take in waste materials and waste water and an extract nutrients from mann's office. we've very 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 property, amongst the best organisms for producing food. but i don't know the

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 cave in particular, is of special interest to the german expedition team. the what they discover here is mind blowing. me sure. yeah. like a toast. finds organisms that bear witness to the very origins of life on earth, the kind of him, how much do you have just found

a huge patch with one of the oldest sonya in effects. henry aware aware of the big catch. incredible, this is i've never seen anything like that. it's quite incredible. i'm going to loss to what we fidget, clock about, right. what's left him speech list 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 isolating. you sign a bacteria and use them for biotechnology classifications. 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 photosynthesis with this device. but 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 can debris and cave is a godsend. the only person might just see a mazda you're looking rock face. but for the biologist, it's a window into a fascinating world. an extraordinary multi generational colony. fidget isn't having. you can see these colorful surface here. these fluffy little gray green pads doesn't get these assigned and back to syria. so with these yellow ones here, these pink jelly light flowed so striking the optic, that's the particular sy entered bacteria and we're off the glow. we go 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 along side more modern spacing is a bit of a voltage differently. they're all living here in the college and career. this is like the misha lack of toasts and 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 these days. 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 than that. if we found different species, a certain process is a different to you and or either. so the allergy here was quite class 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, you know, a 100 down, and there's only 800000. the line from above can reach something as a volume for losses. in the dog is

a little by simply structure that physiology about that photo synthesis and so they can use nothing. 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 in that and the random non or in the fall. right. and what 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 him saturday and campbell 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 and materials that he has not just the biological aspect, which is already fascinating it and that's, but it's also the practical application of something. so you know, that really got to him, but i think in that regard, patrick and michael's ideas are in line with us and like, and other words, we think we're happy to continue supporting them here. and we're looking forward to

working even more closely with the programs, but it's not it. is that a push it the 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, escape and come up if it's time to take one those that idea. and if you had to give them to lines perfectly with the original plan to draw on that potentially lease unexplored micro organisms like gap that all apparently capable of producing substances that have not yet been resend, beautiful people, it all takes rings to just a moment. so these organizations are in 5th competition with each other. so they put to you santibanez things, sort of these, most of it didn't know, not going, but india and today you was interested in it on a tv, i think like produce new tooth as a service. food for other organisms. so they could serve as food for special

typically deal could all be possible, but english, i understand, he meant that the on, but he said 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 world. 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 and large piece your stuff on. for example, here, you know, if i selected for cops at the oaks extra me, i'm talking to the units cellular. how guys we've isolated mike or call us for it. like how go from very hope that's a region. so when i complete the new alga, we've identified even from sol involved in the arctic of the all can attend the, to the country. what does that do? the, the kind of you have to do it has a small 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 and there were some of that kind of coping ice, for example. cool how they behave like rebuilding carl and producing a sort of troy piece kenneth. and she is one of our new projects here is to see whether we can use this as a submitted substitution as a cement, as a can be crossed. and um, yeah, 2 bucks. that's a minute of all the samples we collected during here. do you think of something that tom determined researchers are traveling the world on the hunt for new species of algae? the most recently spent 4 weeks in the add a comma desert and she'll a while a whole spine. it's a cactus here. the other trend to polio samples, that's a special type of liking that grows on the tips of the tax side in inverse 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 and by technological reactors, for example on somebody they will temper to an old phone. that's number one. number 2 in extreme habitats like that to organs. new boys find organisms can do something very special from such as producing special active substances except for adopting specific metabolic pathways. stuff like the big armstrong. some algy enter into symbiosis with fund guy in order to survive and extreme places forming legans. patrick young. the found such l, g, fungus, symbiosis, in the out of comma, the fun, this becomes a kind of sun shade for the algae does, is on the, on the, among other things. it also provides you the protection against the hush radiation one finds in the to come and visit the l g e, and not mobile. they trumped 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 this ones that task falls to the funds will talk to them as they produce a certain pigments in the case of these think she's 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. a beacon view, how between 10 organic waste and the plastic. early march 2022. the official launch of a research project called a 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 ality. green

fuels could also be created using the same methods research as being funded by the german federal state of rhineland to pull out nate, they see it as an investment in the future. going to just the one that in those kind of heard of that from the state level, many companies would benefit from becoming a little less dependent on energy supply. as a credit, that's a significant consideration these days are no, we'd also be making a contribution to climate protection from here in rhineland class and it's about france. i was kind of trying to hold the german federal ministry of education and research is also funding the project. they've granted 8000000 euro. so for the 1st 3 years, some in several partners are working with the team from amazon. and it says it's unknown to your god at all, but currently in joining an additional spock of interest move, just hoping to progress as far as possible with the companies findings ultimately incrementing some of the only thing is we've been, we're searching for. yeah, so on this one, got it under forced tom. yeah. minds of yes,

wonderful was just right. 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. a lazy thing. nothing is funny so they don't grow as well. documents, i think rubbing a controlled amount of stuff. i don't know, large scale this isn't that we can then controls that grows here, and it kind of pre culture and transfer them into the loan to react because you have to one instance soon analogy that's popular with biologists will be growing in this reactor. as of some buyers for you. so this for example, is the land price people to buy a technologist working without doing anything with the systemic assistance. so it's used quite frequently and curbside daily and conditions like past the due of 2 months. so that's what you see here, for example, here of the terrestrial. i'll give you a list of dental stuff and score the multi cellular and threat like the little

met. select these fill them in to you can see immediately they tend to clump together or you have to prevent that one with this mixing process. yeah, we're curious to see how we sound be close and then then we have no experience with it yet. the, the, the other than vix, this. so i'm on what kind of follow that you haven't tried yet. yeah, the comp time is it will 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 for climate friendly summit one day exist. 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 the launch or industrial scale and couldn't that's a whole other botox isn't is extended on us not 100 percent. that took the longest

the least connection. its 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 and c o 2. there are other benefits as well. some algy produced natural dies, some could end up on our plates. lots of the marble now we have solar systems on the roof and future. we could also cover the east and west facades with these i'll give you access. i then even collect this would regularly come by to office the for the whole we thomas also food order cabins is the essence cuz a lot of research is still required though space to the new research reactor will soon be housed in this former changing room. and we'll be back for a visit once the researchers have filled it with algy. for now,

it's back to spain. misha locker towson, his spanish colleague, kept 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 to 5 stuff or upsets or to sign a bacteria can say, can waste materials and waste water and extract the nutrients from having a very different lights like we have a um they've been compared to. so could you put it in as like in the volume of the cod 2 weeks hail to feed, creating oxygen and food at the same time by on now make a products and other out 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, i know sec by selling products. okay. the young thing would be actually to be a mass, not taking advantage though we're not the mouse. why don't we come made mistakes? diana and i can stay on the bus to have him play the bid of something. but of course i can read, i can kind of best buy up there and you're going to let me buy all a g as an important area of research for this 1st bound. mars expedition and algae could play a key role here to the main line of investigation with office headquarters, engineering of course, on biology. everything when it comes to of the protocol for the searching for light on so long i the new teams and how come we want to be somebody that we need to

research as a pc and a ton of ours. you know, so everything that i've been to and should hyphenate techniques and your team cuz you on a food unity. so all that stuff is mostly based 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 in them. 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 we're probably many, many different organisms living together have a little microcosm, so to speak in the hospital when that's what we want to find out on the need shuttle to do that. when we're carrying out genetic analysis to determine which organisms are living together here on this form, 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. the researchers can grow various algae and the reactor unimportant step in cultivating alternatives to environmentally harmful plastic because of 4 times on this one. the other great advantage of this out to put on a stock is that it can produce by protesting. so that means if you give it sugar, so we should think given the additional carbon sources and fixed costs to produce material cost 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, uh, 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. the problem at the moment going bike level w w. s. study here is the we ingest, around $100.00 micro particles of mancha plastics with each meet. oh, that's the equivalent to the 2000 pulse because a week or 5 grams each week. um, that's the equivalents of the credit card division in miner could take that means the don't average that everyone in the well, there's every week is each and 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 every one can watch algae at work in their own window. the americans 1st, this is cooling called, so to speak to you about some of these even much less voltage. just an aerosol sprite, 90 percent less full time. they have better gas exchange, the easier to harvest. and so that's what this is on us model for growing sign. and

bacteria in the future, in sort of 2 out of 10 not just dies, could be grown here and these beside windows or cosmetics or even food. i didn't, you know, the cussing somebody out even in china? no. yes. as a traditional in yes dish, for instance, worse, 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 and parents 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 drugs. this block is now 1st prototype. i'm about to, to you. we introduced to cyan and bacteria strain into the concrete in process. it's not yet one from the case. the, this is a bar tree strain energy about how we carry down south those preliminary tests with

a test to see whether this process works with cyan or bacteria, or a tool in the loan to we want to work with the cyan and bacteria from the cave since they calcified naturally, we can then use the process for concrete productions in this way. the system will 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 fat 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 question is, which one goes at the bottom in which at the top of this one here, and that there is little algy research here michelle. alaska chose the seeing the modules for the 1st time today because audio remedies type, amazing key to we need to really think, okay, that should defend roughly key,

but then you see how big it is in reality and to do minutes. as i mentioned that we've never had before, and that's also really important, does look, we're always working on a bar to scale news. 100 milliliters by maybe 10 meters is the largest size, but see in our 100 leads to. but that's a whole of a story that we're really getting into it now on the ground. this guy, i don't think me personally going. it's going in close. and steve, the, the state of rhineland collab, nate is picking up the bill around $80000.00 bureaus 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 l g. there is nothing can put on right, and that's as far as the water comes in from the top just just makes sense and then spreads through the holding. terry, on the when it drips down it's fed outlook and at the bottom, then circulates back to the top, 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. but when i read the cool for 10 does and so bio reactive at 1st i wanted what it won't. so is it something it's all make? that's what it sounds like. it 1st go in retrospect so it makes a lot of similarly, some goals. i must say, i find what they doing. they have very interesting discuss. i'm a fan of the projects within for you. i'm gonna find it to prevent the algae in the module from getting too much light or dying from overheating. sun protection is built in the, in the stuff inside of the react and must get too hot. good. because otherwise the out you would get to halt as well and die. um yeah, that's why we've changed it from the sun 1st from above. and then again, from the side, the event will hang cold by the recounts, and the costs that will sprout or provide even more shade for the result. is this, under course the 1st type of especially for the to the l g and the reactors will

soon be producing bio plastic and absorbing c o. 2 from the air. they'll be hung on an actual facade and should guard for research purposes me say a lack of toast 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 where in the 1970s we've developed it. so just making a new craft quickly, we can actually get them to use those on the 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 farmers and still have a lot of exploring to do in every corner of the planet,
