to have to say, that's why we listen. because every weekend on d w, the hope has a color, it 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 ability, like limes to creating algy, which might one day generate climate neutral summit for 10 to verify percent of blood black as far as c o 2 come some construction to the concrete production. yes . 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 didn't come up 1st, go for up 1st name and i'll give you all can take in waste materials and wasteful to then an extract nutrients from his office with very light and they can also produce oxygen. so as i can find the c o 2 weeks heil create to oxygen and food. same time on this. okay, probably amongst the best organisms for producing food, but i don't know the

done an expedition in northern spain, an hours drive from build out these researchers led by 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. lack of toast, binds organisms that bear witness to the very origins of life on earth, the god of impoverished, you've just found

a huge patch with one of the oldest sonya in effects. henry, 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, 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 on one, we really want to discover and isolate new sign a bacteria and to use them football, technological applications. at the same time thought when we have in such a marvelous habitat, the 1st question is naturally, how would they survive? 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 prices for the algae researchers, this can't brienne cave is

a god sent a late person might just see a mazda and booking rock face. but for the biologist, it's a window into a fascinating world. an extraordinary multi generational colony. did you do some shopping? you can see these colorful surface here. these fluffy little gray green pads doesn't. it's visa, cyan, or bacteria. and so 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 leaving. so i entered bacteria and back to so it's a very basic primitive site and a bacterium that's living here along side mo martin space. it is a bit of a volt, differently getting either old living here in the colon, including this like the misha lock, a toast and patrick young are through with the wealth of research material they've 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 low really mathias is. also the question of how exactly this works in the low light 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 is 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 l. g. living here to feel comfortable, you know, 500 down, and there's only 800000 the line from above can reach them as a volume for losses in the dog. they simply structure that physiology about that photo synthesis on the screen so they can use most certainly 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 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 him saturday and campbell a. you'll get tons of a new field for such. i find it very interesting in terms of the production and research of useful substances and materials. it is 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 a and i can other words, let me 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 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 knows that idea. and if you had, there's a few minutes a lines perfectly with our 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 recess. beautiful on a to point out 6 rings to just a moment. so these organizations that are in 5th competition with each other. so they put to you santibanez things sort of these most a didn't know, not incompetent yet. and today you was interested in it on and see if you think like produce new truth doesn't serve as 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 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 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 here we've isolated micro claudia for it like how go from very hope that's a region. so when i complete the new alga, we've identified even from solve up in the arctic of the all can attend the, to the candy. what does that do? the, the kind of, you have to what has a smaller renting or the quite unusual that we don't know why it's the i just, i,

as 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 that by the kinds of iceberg companies, there were some of that kind of caught up in ice, for example. cool. how they behave like rebuilding car on kind of producing a sort of truck. he's kinda tough. 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 invent things of all the samples we collected are in 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 the whole spine of the 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 an ex, prerequisites are extreme locations. it's very hoss and there's little volta venue

of the organisms can survive. the i can also withstand very high temperatures in 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 organise new boys, find organisms that can do something very special stuff, such as producing special active substances except for adopting specific new metabolic pathways. stuff. it's a 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 does. when the and the among other things, it also provides you the protection against the hush radiation one finds in the to comment is it is the l d a no mo bile. they're trapped in a stationary position and somehow have to protect themselves from the sun's rays,

which they can't avoid with the like. and like this ones that task falls to the funds will talk. know that mistake produces that and pigments in the case of these 3. she's those pigments that green is yellow in appearance. 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 vehicle in the house. we turn organic waste into plastic. 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 ality. green fuels could also be created using the same methods research as being

funded by the german federal state of rhineland, polite, nate, they see it as an investment in the future on gifts. the one that in 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 credit, that's a significant consideration these days are no, we'd also be making a contribution to climate protection from here in rhineland. pleasant as reference, i was kind of kind of to hold the german federal ministry of education and research is also funding the project. they've granted 8000000 euros for the 1st 3 years. some several partners are working with the team from parents, ends, and it's also known to be a condo, but currently enjoying an additional spark of interest move just hoping to progress as far as possible with the company's 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. just right. so the 2 researchers are unpacking

a new piece of equipment. a photo bio reactor that 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 is little girl as well documents, i think ro, an a controlled man and stuff. i don't know law kyle, this isn't it. we can then control that grows here. and it kind of pre culture and transfer them into loan to react with exact tooling. and 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 elaborate to buy a technologist working without getting with the system the consistency. it's used quite frequently and copes ideally and conditions like past the due of 2 months. so what do you see here? for example, of the terrestrial out, can you write those internal stuff and score the multi cellular and threat like the

little met cindy, is feed them into. you can see immediately 10 to clump together when you have to prevent that. what 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 convicts this. so i'm on what kind of follow that you haven't tried yet. yeah. zoom a comp time is it. so we'll take a do in here. we don't even know yet what carrier stuff is most fund you want us to expire, 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 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 and now we have solar systems on the roof and future. we could also cover the east and west for solids with these i'll give you access. i then even collect this would regularly come by to office the for the whole we to all of us, all cells, food order captains is the essence. cuz noise, 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 up. so that's, that's a sign of x. 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've been compared to so i'll just put it in. as i can find the cod 2 weeks hail to feed, creating oxygen and food at the same time. by on now i'm going to put up some other . i'll probably be among the best organisms for producing food in the space and can embed. i don't know what's important 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 mass by taking advantage that we know the mass when brand new. we come made mistakes. diana and i can stay on the bus to have him play the bid of something. but it, because i didn't really 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, the main lines of investigation with office headquarters, engineering, of course, on biology. everything when it comes to the protocol for the searching for light on so long. i've been new teams and how come we want to be somebody that we need to research a pc and a ton of ours. you know, so everything that i've been to and should hyphenate techniques and your team per

lucy on a food unity cell. all that stuff is mostly 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 again, and then we'll analyze the samples and then definitely take another look at that cheat. so we want to really say 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. 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 step in cultivating alternatives to environmentally harmful plastic. because the 4 types you up on this one of the crate advantage of the se, diploma stock is that it can produce by protesting. so that means if you give it sugar. so should think given the additional carbon sources and fixed costs to produce material gas it and that's the basic building block for a really great fire. plastic that's called p h. b for chauffeur's. buick sauce tickets 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 tired of this of

this. the problem at the moment going by global 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 equivalent of a credit card division in minor to take that means the don't have rich 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 everyone can watch algae at work in their own window. on the marketing services, this is our calling called so to speak to you about some of these, the much less voltage, just an aerosol sprite, 90 percent less full time. they have pets, of gas exchange, the easier to harvest. and so that's what this is on us model for growing side effects here we are 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. this is this machine of the cussing somebody. how do you use even in china? no. yes. as a traditional new yes dish, for instance, verse, that's the most talk flag in the form of i'll give it's collected from the test, but 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 on to 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 introduced to cyan. it back to you area strain into the concrete thing process. it's not yet one from the cave. the. yeah, this is a bar treat strain about how we carry down south those preliminary tests with it test to see whether this process works with cyan or bacteria, or

a total of on in the loan. so 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 can be another 2 to 4 years before we've optimize the system is going to send to tell us where on the right track in our fat, in the i full region, a metal construction company is building for large file reactors. the window modules will be 2 meters, 40 high one meter 42 across now the questions which one goes with the both and then which at the top of this one here and that they're l. g research or michelle lack of chose the seeing the modules for the 1st time today. of course i do at this time. amazing. we need to really think, okay, that should have been roughly key,

but then you see how big it is. in reality, it's, if i mentioned that we've never had before, and that's also really important because of, we're always working on a larger scale. use 100 milliliters by maybe, and this is the largest size, but see in our 100 leads just sort of as a whole of a story that we're really getting into it now on the ground. this guy, it'll take me fish to going, it's gonna include and steve of the, the state of rhineland. collab. nate is picking up the bill around $80000.00 bureaus to produce 4 modules. 3 actors 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 them right on. the water comes in from the top just just makes sense and then spreads through the whole entire area on the when it trips down, it's fed out again at 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. but when i read the cool for tend 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 sense to me. so what i must say, i find what they doing. they have very interesting discuss. i'm a fan of the projects within for you, and you'll find that 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 disruption 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, 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 pumps and the codes that will surprise or provide even more shades for the result. is this under course of this type of assessment, put them back to the lp 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. l. g 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 with photo more tight and then the west flow to full tanks where in the 1970s we've developed it. so just being a new crowd quickly, we can actually get them to use those on the houses in houses. ultimately, that's up to the politicians inside of to put it. if they subsidize, it doesn't feel good will happen very quickly without the size of the world of cost . well, certainly part of the mix forced time from feeling good for now, the l. g researchers from parents and still have a lot of exploring to do in every corner of the planet the,
