Sentences with phrase «into cyanobacteria»

If enzymes are genetically introduced into cyanobacteria, thanks to their catalytic function they will drive the chemical reaction, thus rendering the expensive reducing equivalent superfluous.

Not exact matches

Church and colleagues are also adapting the approach for use with other useful bacteria, including Shewanella, which can convert toxic metals such as uranium into an insoluble form, and cyanobacteria which can extract energy from light using photosynthesis.

«When Paul Cox came out with his paper saying that cyanobacteria produce BMAA,» he says with a lingering Texan twang, «I thought, whoa, we'd better look into this because here in Florida we get some really big blooms.»

The researchers now think that cyanobacteria played a larger role than previously believed in creating phosphorites in shallow waters, thereby allowing today's scientists a unique window into ancient ecosystems.

The alga or cyanobacterium produces food by converting energy from the sun and carbon dioxide into sugars.

Wynn - Williams will soon use a mini Raman spectrometer — called a CMaRS — that he can carry into the field in his backpack to detect the fossilized pigments of ancient cyanobacteria.

Since the detection of the toxin microcystin left nearly half a million Ohio and Michigan residents without drinking water for several days in early August, discussions of ways to prevent a recurrence have largely focused on the need to reduce the amount of phosphorus fertilizer that washes off croplands and flows into western Lake Erie to trigger harmful cyanobacteria blooms.

«The blooms are problematic because you can't enjoy the lakes, and because certain blooms of cyanobacteria can release toxins into the water, which impacts fish and other wildlife.»

Cyanobacteria, which still exist in a similar form today, probably started using energy from sunlight to photosynthesize some of the carbon dioxide in the atmosphere into organic compounds.

According to Schopf, the fossils he found in Western Australia indicate that Earth's earliest inhabitants resembled cyanobacteria, single - celled organisms that turn sunlight into energy.

Biologist Willem Vermaas of Arizona State University recently engineered cyanobacteria to accumulate up to half their dry weight in fat; just by opening up the cells, he can harvest the stored fats and convert them, in a few simple steps, into biofuel.

The experiment showed that, without this enzyme, these cyanobacteria could no longer synthesize chlorophyll f. By artificially adding the gene that encodes the enzyme, the researchers also showed that this one enzyme is all that is necessary to convert cyanobacteria that normally do not produce chlorophyll f into ones that can produce it.

«Our lab and others have put a gene from cyanobacteria into crop plants and found that it boosts the photosynthetic rate by 30 percent,» he said.

Cyanobacteria absorb light energy from the sun and use it to convert carbon dioxide into food and other molecules, while also giving off oxygen.

In a paper published online today in Science, Chisholm's team reports that cyanobacteria secrete vesicles — small, membrane - enclosed sacs — into the surrounding ocean.

Sonntag and his colleagues have adapted a computer model that describes the mixing of layers of seawater to take into account two kinds of changes produced by the cyanobacterium Trichodesmium: more light absorption and less choppy waves.

At that time common biologic knowledge is: Biogene methanogenesis is performed by archaea, (perhaps some cyanobacteria, fungi and microalgae) which can be divided into two groups: — H2 / CO2 - and — acetate - consumers, (both groups have proteins, carbohydrates or lipds an their derivatives as source).

Many of these microbes persist today; for example, blue - green (cyanobacteria) or bright green, photosynthetic bacteria use light from the Sun and chlorophyll to convert carbon dioxide and water into «free» molecular oxygen and carbon, made into essential organic substances such as carbohydrates.

Eventually, however, terrestrial red and green algae and the first lichens developed on land and the final big rise in oxygen may have been caused by the «greening of the continents from around 800 million years ago,» when these simple early lifeforms on land steadily spread and broke down rocks that sustained a higher rate of erosion and led to the release of more nutrients into the oceans that stimulated even more photosynthesis by more newly evolved algae as well as older cyanobacteria (Nick Lane, New Scientist, February 10, 2010).

The cyanobacterium thrived in the cell and eventually evolved into the first chloroplast.

These are glued together into a mat of tiny organisms called cyanobacteria.

Like its cousins, common forms of algae, cyanobacteria suck in huge amounts of carbon dioxide from the environment and convert it into other materials, such as biomass.

Cyanobacteria's metabolic byproduct, oxygen, rusted the earth, pumped enormous oxygen poison to them into earth's atmosphere, and in so doing paved the way for aerobic - based life to emerge and diversify; cyanobacteria's contributions to life led to their own prodigCyanobacteria's metabolic byproduct, oxygen, rusted the earth, pumped enormous oxygen poison to them into earth's atmosphere, and in so doing paved the way for aerobic - based life to emerge and diversify; cyanobacteria's contributions to life led to their own prodigcyanobacteria's contributions to life led to their own prodigious decline.

Is it the long - awaited, predicted and scientifically reasonable CO2 fertilization feedback effect on the oceans» vast biomass of CO2 - consuming cyanobacteria, albeit also driven by the (literally) «shit - loads» of nitrogen compounds the human race is also pumping into the oceans — thereby shifting sea surface albedos, reducing evaporation rates and troposphere relative humidities (ringing any bells here, bros)?

Cyanobacteria turn carbon dioxide, a global warming gas, into carbohydrates and other carbon - containing polymers, which sequester the carbon so that they're no longer global warming gases.
