Bioremediation Activity of Acclimated Streptomyces sp. in Solid and Liquid Waste.

In the recent years, Uttarakhand has emerged as one of the most attractive industrial destinations in India. The industrial sector of the Uttarakhand state is growing day-byday, and the industrial effluents, disposed by the industries, cause environmental pollution. The industrial effluents have many pollutants, including heavy metals. The major environmental problem is the pollution of heavy metals, and they cause serious diseases in animals, including human. In the present study, the streptomyces strain isolated from sludge contaminated with heavy metal was trained for heavy metal remediation and used for bioremediation activity for chromium, copper and lead in the waste. The metal chromium reduction ranged from 0.386 to 6.42 mg/L, which showed maximum reduction in chromium by Streptomyces sp., copper reduction ranged from 0.288 to 1.129 mg/L, and reduction in lead ranged from 0.063 to 0.286 mg/L. In future, the gram positive filamentous streptomyces strain can be used for chromium ion reduction as bioremediating agent. [ABSTRACT FROM AUTHOR]
