Biodegradation of Lignin Containing Waste
Subject area: Science,Engineering and Technology · Area of research: Microbiology, Agricultural Microbiology
Abstract
Interest in lignocellulosic materials is growing due to their potential as replacements for high-value chemicals derived from petroleum derivatives and their applications in biofuel production, the paper industry, sorbent production, activated carbon, carbon fibers, and bioplastics. Lignin, a complex polymer found in plant cell walls, is a major component of lignocellulosic biomass and poses a formidable challenge for degradation due to its intricate and non-uniform structure. Biological methods, particularly via biotransformation and degradation, have gained attention as economically and environmentally friendly options for lignin utilization. Fungi and bacteria are the primary organisms capable of lignin degradation, with fungi being more efficient but bacteria offering advantages in terms of pH, temperature, and oxygen tolerance. Lignin degradation involves the production of ligninolytic enzymes such as lignin peroxidase, manganese-dependent peroxidase, versatile peroxidase, dye-decolorizing peroxidase, and laccases. The paper industry generates a significant amount of lignin waste, and its treatment using physical and chemical techniques is expensive and results in sludge. Biological approaches offer a more sustainable and cost-effective solution. This review highlights lignin biodegradation by bacteria, ligninolytic enzymes, and the current state of knowledge on lignin degradation from the pulp and paper industry. Further research is needed to explore the potential of bacterial strains and enzymes for effective lignin degradation and wastewater treatment in the paper industry.
