Comparative Physiology and Biochemistry and Taxonomic Assignment of the Chlorella (Chlorophyceae) Strains of the Culture Collection of the University of Texas at Austin¹

The species of the genus Chlorella exhibit considerable biochemical and physiological differences. Therefore, it is important to select for and utilize in research or biotechnology correctly identified strains of the species having the most favorable properties for the respective project. We examined the Chlorella strains of the University of Texas collection at Austin, Texas, according to species‐specific chemotaxonomic characters and assigned 58 strains to 10 well‐established species (only 17 of these strains were correctly named before).
