EnZolv delignification of cotton spinning mill waste and optimization of process parameters using response surface methodology (RSM).

Background: EnZolv is a novel enzyme-based, eco-friendly biomass pretreatment process that has shown great potential in the field of textile engineering and biotechnology. It employs laccase from Hexagonia hirta MSF2 and 2% ethanol in the process of delignification. The process is designed to evaluate optimal conditions to remove lignin and other impurities from cotton spinning mill waste (CSMW), without compromising the quality and strength of the fibers.

Delignification of the cotton stalk and ginning mill waste via EnZolv pretreatment and optimization of process parameters using response surface methodology (RSM).

The present study aimed to add value to cotton waste biomass using a more eco-friendly process, EnZolv which delignifies cotton stalk and cotton ginning mill waste. A maximum delignification of 68.68% and 65.
