Lignocellulosic biomass represents a renewable and abundant resource for sustainable bio-based products. However, the high lignin content in wood hinders efficient biomass utilization. Traditional chemical pretreatments often involve harsh conditions and generate toxic by-products, which limit environmental and industrial applicability. This project explores the application of Novel Alkaline Laccases as a green, enzymatic alternative for biomass pretreatment. These enzymes operate under mild conditions, enabling the selective degradation of lignin while preserving the natural structure of cellulose and maintaining a high hemicellulose content. Furthermore, Alkaline Laccases offer the advantage of biodegradability and function without hazardous substances, aligning with principles of green chemistry and sustainable processing.
