Ecosafe bioremediation of dairy industry effluent using Streptomyces indiaensis ACT 7 and Streptomyces hygroscopicus ACT 14 and application for seed germination of Vigna radiata

Abstract

Marine actinomycetes strains of Streptomyces indiaensis ACT 7 and Streptomyces hygroscopicus ACT 14 were efficiently utilized for the bioremediation of dairy industry effluent. The effluent characterization before and after the treatment were observed. The maximum reduction of TS, TDS, TSS, biological oxygen demand (BOD), chemical oxygen demand (COD), chloride, oil and fat content were observed for effluent treatment by mixed consortium. It showed the reduction percent of 92.57 and 90.73 for BOD and COD, respectively. The untreated and treated effluent was used for the germination of Vigna radiata. The seed germination of 100 and 70% were observed for treated and untreated effluent studies. The seedling length (27.2 cm) and vigour index (2720) was maximum for V. radiata treatment with treated dairy effluent.
