Choricystis

Choricystis is a genus of green algae in the class Trebouxiophyceae, considered a characteristic picophytoplankton in freshwater ecosystems.[1][3] Choricystis, especially the type species Choricystis minor, has been proposed as an effective source of fatty acids for biofuels.[4][5][6] Choricystis algacultures have been shown to survive on wastewater.[7][8] In particular, Choricystis has been proposed as a biological water treatment system for industrial waste produced by the processing of dairy goods.[7]

Choricystis have been found in natural bodies of water in South America,[5] North America, Europe, Asia, and Antarctica.[9] They have been observed as an endosymbiont of freshwater sponges as well as ciliates like Paramecium bursaria.[10][11][12]

Use as a biofuel

Triglycerides and other lipids can be transesterified to produce fatty acid methyl esters, the primary component of biodiesel fuels.[13][14] Because of their high lipid content and rate of lipid production, Choricystis algae have been suggested as effective microalgae for industrial biofuel production.[4][5][6][15][16] Molecular profiles of C. minor have noted its high proportion of neutral (as opposed to polar) lipids,[4][8][17][18] considered preferable in biodiesel production.[8][19]
