Summary
Microbial
associations from 10 oxidizing lakes, situated in the region of the oil
refinery Plama Ltd, were
investigated. The general number of microorganisms for each taxonomic group was
determined. The isolated oil-assimilating strains of bacteria, fungi and
actinomycetes belonged mostly to the genera Pseudomonas,
Bacillus, Penicillium, sections Aureus and Cynereus. The inhibiting effect of the oil products and the ability of the
isolated microorganisms to assimilate oil were studied.
