| Research Abstract |
Ten species of bacteria were isolated from mixed cultures of Chlorella (green algae) and soil bacteria. A Brevundimonas isolate significantly elongated the culture lifetime of Chlorella. Bacteria that supply vitamin B_<12> to a vitamin B_<12> auxotrophic green alga, Monomastix, were isolated, one of which, Ensifer sp., was subjected to a molecular genetic analysis. The presense of 22 genes involved in vitamin B_<12> synthesis in this bacterium was revealed, and the full sequences of the genes were determined.
