The aim of this work is to isolate and characterize bacterial isolates form dye house effluent, and to check their ability of decolorizing sulfonated azo dyes, and also to study influence of various environmental parameters on same process. Among seven Gram positive bacterial isolates obtained form dye house effluent, M1 (Bacillus cereus) and M6 were proved to be more potent for decolorizing sulfonated azo dyes under aerobic conditions. Maltose as carbon source and peptone as nitrogen source enhanced decolorization efficiency of M1 (B. cereus). HPTLC studies proved that more than 97% of the dye (Reactive Red 195) was degraded by bacteria after 72 h of incubation. These results along with spectrophotometric data prove the efficiency of bacteria suggesting their possible use in treating dye containing effluents.
本工作旨在从染房废水中分离和鉴定细菌分离物,并检查它们对磺化偶氮染料的脱色能力,以及研究各种环境参数对同一过程的影响。从染房废水中获得的七株革兰氏阳性细菌分离物中,M1(蜡状芽孢杆菌)和 M6 被证明在有氧条件下对磺化偶氮染料的脱色能力更强。麦芽糖作为碳源和蛋白胨作为氮源提高了 M1(蜡状芽孢杆菌)的脱色效率。HPTLC 研究证明,细菌在孵育 72 小时后可将超过 97%的染料(活性红 195)降解。这些结果和分光光度数据证明了细菌的效率,表明它们可能用于处理含有染料的废水。
