[Distribution of bacteria resistant to oxygen-containing anions-xenobiotics].

Regularities of distribution of bacteria resistant to inorganic anions-xenobiotics--chromates, chlorates, perchlorates, vanadates--in different ecologic niches have been investigated. It has been established that these microorganisms are isolated from different ecological niches independent of the pollution degree and geographical zone. Bacteria capable to reduce the studied anions are isolated among the resistant strains in 10 - 15% of cases. Side by side with oxygen-containing anions the studied cultures are resistant to heavy metals (Cr6+, Cd2+, Cu2+, Pb2+, Zn2+, CO2+, Ni2+) and antibiotics.
