OPTIMAL BIODEGRADATION OF METHYL VIOLET ACHIEVED BY ENTEROBACTER STRAIN
AbstractThe most widely used cationic dye, methyl violet (MV), has significant carcinogenic potential. The textile, cosmetic, printing, pharmaceutical, and food processing sectors all make extensive use of artificial dyes. They are typically referred to as xenobiotics because of their strong resistance to biodegradation. Microbes are beneficial because of their rapid growth and ability to break down and mineralise dyes. Methyl violet-degrading Enterobacter sp. was isolated from the Ganges River. It degrades up to 180 ppm of methyl violet in 24 hours when shaken at 25°C – 45ºC and pH 1 -12; optimum degradation occurs at 40 ppm in 24 hours at pH 7.0. The effects of temperature, initial pH, and dye concentration were investigated. The capacity of bacteria to degrade was demonstrated by experimental results. The deterioration of methyl violet was validated by UV-Vis spectroscopy, SEM, and FTIR examination of samples both before and after dye breakdown in culture media.
