title: Numerical Taxonomy of Heterotrophic Bacteria Growing in Association with Continuous-Culture Chlorella sorokiniana.
abstract: Twenty-nine cultures isolated from nonaxenic growths of Chlorella sorokiniana (Shihira and Krauss) and eight reference cultures were tested for 150 morphological and biochemical characteristics. The taxonomic data were subjected to computer analysis from which five major clusters were identified. The bacterial isolates have been placed in the genera: Pseudomonas, Acinetobacter, Flavobacterium, and Bacillus. Amino acid requirements of four strains from the test set were determined.
