Decolourisation of reactive black 5 using Lysinibacillus fusiformis ZB 2
The textile industries cause various problems related to the textile wastewater effluent, including that of discharge and treatment of dyes. The majority of the commonly used dyestuffs which accounted for nearly 50% of the dyes are azo dyes. In this research, the effects of three parameters includin...
