Microbial Decolorization of Reactive Violet 1: Biosorption Optimization by Central Composite Design

Abstract

Biological treatment of wastewater containing dyes utilizing aerobic, anaerobic, or combined aerobic-anaerobic biodegradation techniques is often utilized due to its relative affordability and lack of hazardous consequences. Different microbes including bacteria, fungi, and algae were used to decolorize the different dyes. Up to 10% of dyes used in the textile industry are eliminated as colored wastewater after being applied and are not bonded to the fibers. These colored wastewaters must be properly cleaned before being dumped into different bodies of water. The objective of variety search is to identify the factor combination with the highest desirability combination. Desirability functions are frequently employed in RSM optimization. Four bacterial biomasses have been tested for their capacity to decolorize dyes in this study. Screening studies included four distinct biomasses and four distinct reactive dyes. The bacterial strain #288 has a biosorption with 70% on Reactive Violet 1. Central composite design was employed to maximize the biosorption percentage and biosorption capacity. At the result of the study, Reactive Violet 1 was adsorbed by #288 with 93,7% and the biosorption capacity was estimated to be 325,7. FTIR and SEM were used to characterize the biomass before and after decolorization. The outcome demonstrates that #288 is effective in removing Reactive Violet 1 from textile wastewaters.
