Microbial Flocculant. Part VII. Production of a Bioflocculant by Rhodococcus erythropolis S-1 Grown on Alcohols.

Rhodococcus erythropolis strain S-1, which was isolated from soil, produces a bioflocculant. We have found that alcohols are useful carbon sources for its flocculant production. Ethanol was best for flocculant production and culture time. The bioflocculant produced on ethanol medium flocculated a wide range of suspended soils, alkaline and acid.
