of the treasure map for modern globetrotters. describe it as some of us wriggled, begging sites on youtube, and also input 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 to flow black as far as c o 2, come some construction to go from 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 12 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, doesn't come up 1st, go for a 1st name and outdoors can take in waste materials and waste water and an extract nutrients from mann's office. we've heard that line and they can also produce oxygen. so as i can find the c o 2 we exile create to oxygen and food. same time on this. ok, a property amongst the best organisms for producing food. but i don't know the

as 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. 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 cats incredible. i have 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 speechless is how these bacteria known colloquially as blue green algae can survive with so little light to the noise. on one hand, we really want to discover the isolating. you sign a bacteria and use them for the technological applications at the same time thought when we haven't set them off and us 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 parts for the algae researchers, this category in caves 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. did you do some shopping? you can see these colorful surface here. these fluffy little gray green pads doesn't. it's visa, so i enter that curio. and so with these yellow ones here, these pink jelly live clouds 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 so it's a very basic primitive site and a bacterium that's leaving here along side more modern spacing is a bit of a voltage differently getting either old leaving here in the colon included. this is like the misha lack of toast 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 this works in the low line situation. we've been counted deeper inside the caves, so i entered bacteria population. there is different than that. we found different species. a certain process is a different to you and either. so the allergy here was quite tough, august responders and i can yes, they can photo synthesizing the dog and 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, a 100 down, and there's only 800004 line from above. can reach them as a volume for losses in the dogs is a little they simply structure that physiology about that photo synthesis and the

thing so they can use most certainly the visible light spectrum. but this would be speech the exciting of this. and they may also be able to draw from further along the range of light in that, in the random non, or in the fall. right. and what this will go smoking couldn't understand though 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 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 of something, you know, lovely. got you and, but i think in that regard, patrick and michael's ideas are in line with us. and mike and other words, you think we're happy to continue supporting them here, and we're looking forward to working even more closely with the bill you're gonna

have to, for the most part, it's not it. is that a push a till 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 escaping come up if it's time to take one knows that idea and if you just give them a 6 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 resend to kind of people. it all takes 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 of it didn't know, not incompetent yet. 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 us to feel simple. the 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. the more space you or the i'm for example here, your vice electrical cox and the upstairs from the i'm talking to the unit cellular . how guys 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 in the optic of the all can attend the, to the country. what does that do? the, the kind of jobs of what has a smaller renting or the quite unusual that we don't know why it's the end style.

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 divided couldn't suffice because there were some of that kind of coping ice, for example. cool. how they behave like rebuilding carl and producing a sort of truck, he's kind of tennessee 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 old and who samples. we collect tutoring here. do you think of something that tom, the german 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 and here the other trend to police samples. that's a special type of like, and it grows on the tips of the tech side. in the next prerequisites are extreme

locations. it's very hard. and this little volta venue of the organisms can survive that i can also withstand very high temperatures in by technological react, as for example, one. so by zillow tempo to an old one, that's number one. number 2, in extreme habitats like that to organise new voice, find organisms can do something very special stuff, such as producing special active substances except for adopting specific you meant to pulling call twice. stuff like the big armstrong, some algae 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 that is on the, on the, among other things. it also provides you the protection against the hush radiation one finds in the to comment is it is the lp and not mo bile. they 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 ton devastate, produces it, 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 beacon view probably between 10 organic waste and the plastic funding on 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 ground 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 green 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 on gift stuff on 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 theater in rhineland. blessone, it's reference, i was trying to try 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 pam events and his shots unknown to get caught out mccartney and joining an additional spock of interest move just hoping to progress as far as possible with the companies i need to ultimately implementing some of the only thing is we've been, we're searching for yes. so on this one. got it on the 1st top. yeah. mine's of yes . wonderful was just right. does 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 says he sent me some documents for 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 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 curbside daily and conditions like past the due of 2 months. so that's what you see here, for example, each of the terrestrial out. can you write those internal stuff in the score? the multi cellular and threat, like the little netcinity 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 then we have no experience with it yet the, the, the, that 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 doing here, we don't even know yet. we carry out as much 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. and so this isn't close that window seed ups 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 lot of botox movies. and he was extend on us not 100 percent. that took the longest movies 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 a lot to me and now we have solar systems on the roof can future. we could also cover the east and west for thoughts with these. i'll give you access, i then even collect this would regularly come by to office the whole we to all of a star cells, food order cabins as 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. 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 lack of toasted 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 not to go up 5 stuff up. so that's a to sign. a bacteria can take and waste of materials and waste water and extract the nutrients from having a very different light. just like we have a light then compared to you. so you put it in as i can. the volume of the c o 2 weeks heil to free creating oxygen and food at the same time, i don't know much of products and i'll probably be 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 if we need to take a look on the piano sec by selling products. okay. the young thing would be actually to be a mass by taking advantage that we have another mass when brand new. we come made mistakes, tyanne and i can help us to have him play the bit of some of the course i didn't read that can help us to, to buy up. then you're going to 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 office i call g engineering. of course, on the device that you, every seeing when it comes to of the protocol for the days that you live on so long . i didn't new teams. and how come, why would that 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 hyphen techniques and your team for

those 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 change. 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, have a little microcosm, so to speak in the hospital when that's what we want to find out about the need shuttle to do that. we're carrying out genetic analysis to determine which organisms are living together here on this form. back to pair me is 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 this out diploma stock. is it a commodities by protesting? so that means if you give it should, we should think, given the additional carbon sources from fed, starts to produce material gas at time. that's the basic building block for a really great plastic. that's called p h b for sure. buell plastic that's most by compatible, i'm fine to grind to combustible heated, is it used to sutures in medicine for example, see about is prevented from somebody to, for need of items that seem 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 it's a problem at the moment that's going bike level w. w. s. study here is the we ingest, around $100.00 micro particles of micro plastics with each meal. plastic. that's the equivalent of 2000 pulse because we can't do that or 5 grams each week. um that's the equivalents of the credit card division in minor cooking. that means the tone average that everyone in the world every week is each and a credit card with a plastic. i need to 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 american person, this is cooling, called, so to speak, to you about some of these even much less volt, 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 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, 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 sell 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 up rocks. this block is now 1st prototype. i'm about to, to you. we introduced to cyan and back to you restrain into the concrete in process of it's not yet one from the cave. the yeah, this is a bar tree strain. energy 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 or bacteria from the case 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. too soon to tell us we're on the right track. in our fight. in the eiffel region, a metal construction company is building for large by or 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 there is one of the research or michelle lack of chose the seeing the modules for the 1st time today. of course, audio bennett is tight. 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. there's a for always working on a larger scale, use 100 milliliters by maybe n z 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, i don't think, let me push the 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. 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 on right as, as leaving the water comes in from the top. it just has made sense and then spreads through the whole entire area on the when it drips 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 the 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 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 and it makes a lot of sense to me going, i must say, i find what they doing. they have very interesting discuss. i'm a fan of the projects within for you. i can 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 out of 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 prompts and the codes that will surprise to and provide even more shades for the result. is this under course of this type of especially for them of the actual, 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 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 to use those on the houses in houses. ultimately, that's up to the politicians inside of 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, 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
