the food is not, well, let's go through. so when it comes to the stand you've been, it seems inflammation. and trend this is alex texted on d. w. travel, you can have it, whatever you, what's your opinion feel free to write your thoughts and the comments. 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. 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 depth 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. then an extract nutrients from mann's office. we've already live 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

on 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 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 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, 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 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 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. since you do some shopping, you can see these colorful surface here. these fluffy little gray green pads definitely gets these as 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 glo yo back task. we will 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 leaving here along side more modern spacing is a bit of a volt differently getting either old living here in the colon, including this like the misha lack of toast and patrick young are thrilled 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 lice, but we don't know exactly what the low really mathias is. also the question of how exactly this works in the low line situation. we've been counted deeper inside the cave, so i entered bacteria population. there is different than that. we found different species, a certain process is a different to you and or either. so the elegant 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 algae 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 dog. they simply structure that physiology about that

photo synthesis and 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, we 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 escaping time to take one knows that idea. and if you had to give them to lines perfectly with the 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, beautiful kind of people. it all takes rings to, into the moments of these organizations that are in 5th competition with each other . so they put to you santibanez things sort of, i need most of, it didn't know not on confidence 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 special typically deal could all be possible. but

english, i understand you meant that the on both of you 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 hot as a region. so then a completely new outcome we've identified, even from sol involved and the optic 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 or the quite unusual that we don't know why it's the einstein

researcher 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, 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 truck. he's kind of tennessee is one of our new projects here is to see whether we use this as a submitted, substituting 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 engine. and here the other trend to police samples. that's a special type of like and it grows on the tips of the text side in most if next

prerequisites 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 react, as for example, on so by zillow template to an old phone. 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. it's a big armstrong. some algae enter into symbiosis with fund guy in order to survive and extreme places forming. lincoln's patrick young, 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 come and visit the lp and 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 a like. and like this ones that task falls to the funds will ton devastate, produces it, and pigments in the case of the species. 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 310 organic waste into plastic abundance. early march 2022. 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 greene

fuels could also be created using the same methods research as being funded by the german federal state of rhineland, collab, nate, they see it as an investment in the future and on the 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 here in rhineland, blessing as reference, i was kind of trying 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 up 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 on the 1st top. yeah. mine's of yes. wonderful. just great. 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. he sent me 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, difficult to buy a technologist working without getting with the system the consistency. it's used quite frequently and copes ideally and conditions like basically the of the month, 2 of us. what do you see here? for example, it's the terrestrial out. can you look at those internal stuff and score the

multicellular and thread like this as a med cindy is feed them into you can see immediately they tend to clump together when you have to prevent that with this mixing process. yeah, we're curious to see how we sound the crows and then then we have no experience with it yet. the, the, the that's been fixed. so i'm on what kind of follow that you haven't tried yet. yeah. zoom a comp time as well to do in here. we don't even know yet. we carry out as much fun . you're going to sewage spill that we can move the the reactor is an important intermediate step towards producing larger quantities of bio plastics or climate friendly summit. one day exist and this isn't close that window seat up is a big difference between trying to fools 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 having to set 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. lots of the marble. now we have solar systems on the roof and future. we could also cover the east and west for solves 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. okay. so say 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 minutes of your upside stuff or upsets the side effects. here you can say, can waste materials some waste water and extract the nutrients from having a very different lights, like we have a like then 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, buy or no, no mix of products and other out a probably 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, i know sec by selling products. okay. 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 help us to have him believe the bit of something but it, because i didn't really like to help us to somebody 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, biology everything. when it comes to the protocol for the and you said to live on so long, i've been new teens. 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 eugene per lucy on a food unity cell. 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 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 not to do that 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 and 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 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 fetch task 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, for need of identity. 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 algae forms as white dots all the

time it is on this. but what's a 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 to the credit card division in miner could take that means the tone average that everyone in the well there's every week is each of 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, the 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 side

effects here 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 cheat of the 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 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. these up looks as if this block is alice's prototype. i'm about to, to you, we introduced to cyan it back to serious strain 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 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 felt some ice position on the door and just too soon to tell. yes, we're on the right track. in our hot, in the ice will 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 there is one of the research here . 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 bar to scale news. 100 milliliters by maybe 10 meters 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, 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 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 l g. there is nothing can put them right. as leaving the water comes in from the top. it 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 also when i read the cool to attend isn't so bio reactive at 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 going. i must say, i find what they doing. they have very interesting. i'm a fan of the project, something 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 disrupting 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 pumps and the codes that will sprout and toward provide even more shade for the result. is this under course of this type of especially for them of the actual,

the lp 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 viewed 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 gets 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, certainly part of the mix forced time from feeling good for now the l. g researchers from farmers and still have a lot of exploring to do in every corner of the planet
