Citable articles are intended to be of reasonably high quality. The participants in the Citizendium project make no representations about the reliability of Citizendium articles or, generally, their suitability for any purpose. This article is currently being developed as part of an Eduzendium student project in the framework of a course entitled Microbiology 201 at Queens College, CUNY. The course homepage can be found at CZ:Biol 201: General Microbiology. For the course duration, the article is closed to outside editing. Of course you can always leave comments on the discussion page. The anticipated date of course completion is May 21, 2009. One month after that date at the latest, this notice shall be removed.

Description and significance

Chlorella Minutissima is an unicelluar marine alga that has chorophyll a and b, and synthesizes starch, like plants. Some sources classify algae as plants, such as the Australian Antarctic Data Centre. However, algae are more often categorized into Kingdom Protista, which belongs to domain Eukarya. Therefore algae have membrane enclosed nucleus, yet the internal structures of algae are simpler than those of plants. Chlorella minutissima is rich in amino acids and polyunsaturated fatty acids, particularly eicosapentaenoic acid (20:5co3), which makes Chlorella Minutissima potentially useful in health foods and pharmaceuticals. In the past Chorella Minutissima has been considered to be used as a protein source to the world population to solve the problem of hunger due to two World Wars and the increasing population. Scientists later found that to produce Chlorella Minutissima massively under ideal conditions, the condition would cost a very high cost to maintain. The microalga is an important component in finfish and shellfish aquaculutre 4, therefore research has been done in maximizing the growth and storage of Chlorella Minutissima.
