Review Paper


Fungi are the most important organisms which are involved in the degradation and solubilization of different types of coal. The mechanism of coal degradation and solubilization involves different oxidizing and nonoxidizing enzymes, chelators, alkaline substances and surfactants. This review intends to highlight the advancements in the biotechnological processing of coal and summarizes the recent knowledge regarding the mechanisms involved in fungal solubilization of coal especially the low rank lignite coal which is a natural raw material of enormous amounts and of great value.
