Enhanced elimination of HgCl{sub 2} from natural water by a broad-spectrum Hg-resistant Bacillus pasteurii strain DR2 in presence of benzene
- Univ. of College of Science, Calcutta (Indonesia); and others
Mercury (Hg) compounds are extensively used in agriculture as seed-dressers and pesiticides, in hospitals as disinfectants, in sewage treatment and in industries including pulp and paper and chlor-alkali industries as chemical catalysts. Several thousand millions of tons of mercury are dispersed into the environment every year. Rain water washes mercury from soils and rocks. In aquatic environments sediments are the richest deposits of mercury compounds. The mutagenicity and teratogenicity of these Hg-containing compounds are well-documented. This paper reports on a study of the increased rate of the elimination of HgCl2 by Bacillus pasteurii strain DR2 from natural river water in the presence of organic compounds. This bacteria has the dual characteristics of elimination of mercury compounds and utilization of aromatic compounds in natural conditions. 19 refs., 3 figs., 1 tab.
