Abstract
A mesophilic alkalitolerant aboriginal bacterial community capable of autotrophic thiocyanate decomposition under aerobic and oxygen-free conditions was isolated from reused water of a metallurgical works. The growth of the aboriginal bacterial community was optimal at pH 9.0. Ammonium and sulfate were the end products of thiocyanate decomposition under both aerobic and oxygen-free conditions. Under oxygen-free conditions, thiocyanate decomposition occurred in the presence of nitrate. Nitrite was accumulated as an intermediate product in the course of denitrification, and was subsequently used as an electron acceptor for thiocyanate oxidation. Dinitrogen was the end product of denitrification.
