    Abstract
    This world is getting polluted in different ways. This world has many prime components including soil, water, and air. Every day to meet human needs thousands of mills, factories and are producing necessary commodities. And they are polluting the environment in different ways. Some factories are emitting poisonous gases, some are discharging effluents and liquid waste in the environment which are creating hazardous problems in the water system and in soil. And for this environment pollution one of the prime causes is discharging textile dyes into the environment without treatment. This is a common problem for many countries as well as for the Bangladesh. Textile dyes are chemical substances which can cause serious damages to the nearby eco life. The treatment of the textile dyes after using in the factories is either costly or time consuming. As a result mills and factories are not willing to do the treatment process every time, rather they discharge it without any treatment. In this project textile dye degrading bacteria were isolated from the textile sludge to degrade the textile dyes since this biological process is less expensive than the other existing process. Two bacterial strain Brevibacillus laterosporus and Staphylococcus nepalensis were isolated from the textile sludge which was tested with two textile dyes; they are Yellow 4GL and Reactive Red 3BX. And these both bacteria are very much effective to degrade these dyes. Especially Brevibacillus laterosporus can de-color the Reactive Red 3BX dye in a very short time; even the higher concentration of the dye can be degraded.
