title: [Optimization of cultivation conditions of chlorate-reducing bacteria Acinetobacter thermotoleranticus C-1 for treatment of sewage from fuel mixtures industry].
abstract: Composition of culture medium for cultivation of chlorate-reducing strain A. thermotoleranticus C-1 has been optimized with the purpose to decontaminate sewage from production of fuel mixtures, match production sewage, including toxical oxygen-containing anions-chlorates, chromates in particular. It has been established that chlorates are not toxical for the studied culture in a wide concentration range. The rate of chlorates reduction by the strain C-1 was 50.4 + 2.3 mg/(l x h). Maximum chlorate reduction displays in the medium containing (mg/1) : ClO3(-) - 700; CrO4(2-) - 4.5; phosphates in the form of HPO4(2-) - 0.5; in the form of H2PO4(-) - 4.5; nitrogen in the form of NH4Cl - 50.0; t - 40 degrees C; albumin - 500. It is shown that the optimal ratio ChPC:N:P in sewage supplied for neutralization should be 80:10:1 for the efficient use of the strain.
