STRAIN OF BACTERIUM DESULFOVIBRIO SPECIES 'EGAST-4' USED FOR SEWAGE TREATMENT FROM HEAVY METAL IONS

摘要

FIELD: industrial microbiology, ecology. SUBSTANCE: invention proposes a new strain of bacterium Desulfovibrio sp. VKM B-2023 D "EGAST-4" as an active producer of hydrogen sulfide for precipitation of heavy metal ions from solution. Strain is isolated from sulfate drain in production of synthetic fatty acids. The use of the proposed bacterial strain ensures to increase the effectiveness of galvanic production sewage treatment from heavy metal ions up to 99.9%. EFFECT: bacterial strain indicated above, enhanced effectiveness of waste treatment. 1 tbl, 1 ex
