摘要:Present study illustrates the effectual decolourization and degradation of the textile industry effluent using B. pumilus sp. SRS83, originally isolated from dye contaminated soil. The dye decolourization and degradation activity of the culture was enhanced by optimization. Addition of optimized concentration of carbon, nitrogen and phosphorus to the effluent facilitated complete decolourization of textile industry effluent within 24 h, at pH 7 and at a temperatureof 32±2 °C. Addition of starch (10 g/L), sodium nirate (4 g/L) and potassium phosphates (0.2 g/L) were found optimum for complete decolourization of BHM supplemented with 10% of the effluent by B. pumilus SRS83 in 24 h. The organism showed a 87.18% and 84.91% reduction in COD and ADMI values, respectively of the as it used effluent having an initial COD and ADMI value 5632 and 2674 respectively, after 48 h of treatment.
