Chlorella sorokiniana is a species of freshwater green microalga in the division Chlorophyta. [2] The original strain of C. sorokiniana was first isolated by Constantine A. Sorokin in 1951 from a freshwater stream on the University of Texas campus in Austin, Texas; he labeled it as Chlorella pyrenoidosa strain 7-1 1-05. In 1965, Ikuko Shihira and Robert W. Krauss reinvestigated the strain and found it to be its own species, naming it after Sorokin. [3]
Chlorella sorokiniana consists of single, spherical cells that grow up to 5.5 μm in diameter. The chloroplast (chromatophore) inside the cell is single, bowl-shaped and green but often turns white in old cultures. A pyrenoid is present in the chloroplast. [3] Cells grow rapidly on agar without organic nutrients, and grows well on glucose in light and to a lesser extent in darkness. Other sugars such as galactose and mannose may stimulate its growth less or not help it grow at all. [3]
