Microbial degradation of lignocellulosic biomass for bioenergy production: A metagenomic-based approach

Biofuels are obtained from various renewable biological sources and considered suitable alternatives to conventional energy sources in the coming future. Biofuel is deemed essential to bioenergy, which can help achieve the 2030 agenda of United Nations Sustainable Development Goals (UNSDGs). Lignocellulosic materials convert into fermentable sugars by several pre-treatment methods. Several microbial lignocellulolytic enzymes play a significant role in degrading pre-treated lignocellulosic biomass into biofuels. These biomass-degrading enzymes have been screened only from a few cultured microorganisms. These problems related to biomass-degrading enzymes can be solved by screening novel microbial enzymes using metagenomic approaches.
