Microbial decolorization and detoxification of emerging environmental pollutant: Cosmetic hair dyes

J Hazard Mater. 2017 Sep 15:338:356-363. doi: 10.1016/j.jhazmat.2017.05.034. Epub 2017 May 22.

Abstract

Since the usage of hair dyes has increased in recent time, the removal of residual dye from environment is also an emerging issue. Hair dye contains mixture of chemicals including genotoxic chemical, p-phenylenediamine (p-PD or PPD). The present study reports bioremediation of hair dye using bacteria isolated from saloon effluent. Sugarcane bagasse powder (SBP) was used as a source of nutrient and surface for bacterial growth. The 16S rDNA sequencing confirmed the isolate as Enterobacter cloacae which was designated as DDB I. The decolourization of dye was studied using UV-vis spectrophotometer. The detoxification study was conducted on microbes isolated from fresh ponds using well diffusion assay. The 1mg/ml of dye was effectively decolourised within 18h of DDB I treatment in the minimal medium containing 30mg/ml of SBP.

Keywords: Bioremediation; Cosmetic hair dye; Enterobacter cloacae; Saloon effluent; Sugarcane bagasse.
