Abstract

Textile and clothing industries are major contributor to the economic growth in Bangladesh. Establishment of a number of such industries are imparting huge amount of industrial waste containing different types of chemicals including dyes. Pollutants generated from textile industries creates a huge burden on the environment. Textile industries discharge effluents containing various harmful chemicals including synthetic dyes that are very stable and a threat to living organisms. Bacillus spp. are remarkable bacteria which demonstrated potential to produce diverse kinds of metabolites for different uses. This study focuses on the potential use of Bacillus spp. isolated from the garden soil of Stamford University Bangladesh for decolorization of BemacronBlue RS (BB) and BemacronRed RS 01 (BR) dyes. Four Bacillus isolates were screened out from garden soil and named as 1B, 3A, 2C and 4B. Isolates were subjected to decolorization assay with 0.002 gm/l of BB and BR dyes. Bacillus spp. showed great potential in decolorizing BB and BR dyes, which was initiated after 2 days of incubation. Following 8 days of incubation, decolorization of BB was, 79%, 80%, 75%, 77% and BR was, 75%, 73%, 69%, 89% by the isolates 1B, 3A, 2C and 4B, respectively. This study shed some light on the potential use of indigenous garden bacteria for decolorization of textile dyes to control environmental pollution. Stamford Journal of Microbiology, 2023.

从花园土壤中分离本地芽孢杆菌属，用于合成纺织品染料脱色从花园土壤中分离出本土芽孢杆菌，使合成纺织染料脱色

纺织和服装业是孟加拉国经济增长的主要贡献者。许多此类工业的建立产生了大量的工业废物，这些废物含有不同类型的化学物质，包括染料。纺织业产生的污染物给环境造成了巨大负担。纺织工业排放的废水中含有各种有害化学物质，包括非常稳定并对生物体构成威胁的合成染料。芽孢杆菌属是一种非凡的细菌，具有生产多种代谢物以用于不同用途的潜力。本研究的重点是从孟加拉国斯坦福大学花园土壤中分离出的芽孢杆菌属，用于 BemacronBlue RS (BB) 和 BemacronRed RS 01 (BR) 染料的脱色。从花园土壤中筛选出四种芽孢杆菌分离物，分别命名为 1B、3A、2C 和 4B。用 0.002 克/升的 BB 和 BR 染料对分离菌进行脱色试验。芽孢杆菌属在 BB 和 BR 染料脱色方面表现出很大的潜力，培养 2 天后就开始脱色。培养 8 天后，分离物 1B、3A、2C 和 4B 对 BB 的脱色率分别为 79%、80%、75%、77%，对 BR 的脱色率分别为 75%、73%、69%、89%。这项研究揭示了本地花园细菌用于纺织品染料脱色以控制环境污染的潜力。第 13 卷第 1 期第 1-5 页
