Sara figured out how to boost algae oil levels, a trait that could make the photosynthetic organisms more attractive as a source of biofuels.

To remedy that absence, Golden's lab, along with plant physiologist Takao Kondo and colleagues at Nagoya University in Japan, developed an easy - to - read gauge of changing photosynthetic activity in colonies of the cyanobacterium Synechococcus, a blue - green alga whose one - celled organisms divide as often as once every 5 to 6 hours.

Venter and other scientists are experimenting with photosynthetic microbes such as algae and cyanobacteria (sometimes referred to as blue - green algae).

«Coral breaching, in which symbiotic photosynthetic algae of corals are killed by high temperatures and coral reefs are severely damaged, is regarded as a serious environmental issue, but plausibly, similar phenomena may be ubiquitously found in the ecosystem,» said Dr. Fukatsu.

Even more crustal minerals were formed by plate tectonics with the help of lubricating ocean water, atmospheric oxygen from the successful development of photosynthetic microbes, and land - based lichens (of algae and fungi) and mosses which were followed by deep - rooted plants that hastened the erosion and weathering of surface rocks with the help of biochemical action and the creation of soils as well as new clay minerals.

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times when the water column does not support phytoplankton growth; and (2) as the ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large ice - edge blooms important to the overall productivity of polar seas.

Known as zooxanthellae, these algae live within the coral's exposed polyp tissues and are a crucially important photosynthetic source of carbon for the host.
