Abstract

Lignocellulosic biomass is the most abundant biorenewable biomass on earth and is resistant to degradation. However, the presence of lignin in the biopolymeric structure makes it highly resistant to solubilization thereby hindering the hydrolysis of cellulose and hemicellulose. The utilization of biological methods to degrade lignocellulosic materials has been a very effective and eco-friendly method. The present study aimed to isolate and characterize lignocellulosic degrading fungi from different crop residues. Totally 8 lignocellulosic degrading fungal colonies were isolated from 16 crop residue samples like cotton stalks from various locations. All 8 lignocellulosic degrading fungal colonies were confirmed as cellulose and lignin degraders through conformational test. The efficient lignocellulosic fungal cultures were identified based on morphological and cultural characterization and were tentatively identified as Aspergillus sp, Talaromyces and Fusarium sp. respectively, having significant potential for using them in the treatment of lignin and cellulose degradation

Keywords

Lignocellulosic biomass, lignocellulosic degrading fungi, morphological and cultural characterization.

Conclusion

In this present study, it can be concluded that cotton crop residues are a good source for the isolation of lignocellulosic degrading fungi and fungal isolates such as Aspergillus sp, Talaromyces, and Fusarium sp can be effectively used for the degradation of cellulose and lignin
