Optimization studies on biodegradation of atrazine by Bacillus badius ABP6 strain using response surface methodology

•Atrazine is widely used herbicide that causes harmful effects to living organisms.•A bacterial isolate Bacillus badius ABP6 strain was used in the study.•Optimization parameters showed better influence on the Biodegradation process of atrazine.•Response surface methodology is a promising approach for Biodegradation enhancement by optimizing process parameters. In this study, the optimization of distinctive environmental factors such as pH, temperature, agitation-speed and atrazine-concentration on atrazine degradation by utilizing Bacillus badius ABP6 strain, has been done through response-surface-methodology (RSM). The optimum-conditions after analysis for the maximum atrazine degradation were: pH 7.05, temperature 30.4 °C, agitation-speed 145.7 rpm, and atrazine-concentration 200.9 ppm. The prescribed model was approved for high F-value (95.92), very low P-value (
