Growth Performance of Staphylococcus spp. in Chromium Effluent with Various Environmental Conditions

Abstract

Microorganisms and microbial products can be highly efficient to bioaccumulations of metals, especially from dilute external solutions. The emerging technologies employing microbes provides as alternative to conventional techniques towards metal removal from diverged ecosystem. Hence in the present study an attempt was made to investigate the growth pattern of metal resistant Staphylococcus spp in chromium electroplating effluent with various environmental conditions. Metal resistant Staphylococcus spp was isolated from electroplating effluent soil sediments and the strain was confirmed by morphological and biochemical characteristics. Further, the study characterized the growth of Staphylococcus spp in chromium containing electroplating effluents with various concentration (15%, 20% & 25%) and with different pH (pH 5, pH 7 & pH 9), and various temperature (20°C, 30°C & 40°C) conditions, the results revealed that Staphylococcus spp shown the better growth in 20% chromium containing electroplating effluents with pH 7 at 30°C.
