Marine microorganism Marine microorganism Marine microorganisms are defined by their habitat as the microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism, that is, any life form too small for the naked human eye to see, needing a microscope. Microorganisms are very diverse. They can be single-celled or multicellular and include all bacteria and archaea and most protozoa, as well as some species of fungi, algae, and certain microscopic animals, such as rotifers. Many macroscopic animals and plants
Dunaliella strain is reported to have oil yield of about 37% (organic basis). "D. tertiolecta" is a fast-growing strain and that means it has a high CO sequestration rate as well. Dunaliella Dunaliella is a genus of the algae family Dunaliellaceae. "Dunaliella" sp. are motile, unicellular, rod to ovoid shaped (9−11 µm) green algae (Chlorophyceae), which are common in marine waters. The organisms are relatively simple to cultivate and do not clump or form chains. The best-known species is the extremely salt tolerant "Dunaliella salina" Teodor. A new species of "Dunaliella" was discovered in the Atacama Desert in 2010. It is
