Chlorella autotrophica, or Chlorella sp. (580), is a species of euryhaline, unicellular microalga in the Division Chlorophyta. It is found in brackish waters and was first isolated in 1956 by Ralph A. Lewin.[1] The species is defined by its inability to use organic carbon as a food source, making the species an obligate autotroph.[2] It is sometimes considered a variety of Chlorella vulgaris.[3]


C. autotrophica has many uses. The species has been used as a feedstock for rearing bivalves and fry in aquaculture[4] and as source of the amino acid L-Proline.[5][6] German and Russian scientists investigated the possibility of using the species as a food source for astronauts.[7][8] The algal species is also a candidate feedstock for biodiesel production due to its ability to accumulate triglycerides under nitrogen limitation.[citation needed]
