In paper and pulp industry, pulping of biomass is mainly achieved through chemical methods, which are generally environmentally polluting and not sustainable. The pulping is the preliminary processing step in the paper and pulp industry, which is mainly aimed to remove lignin component of wood without any degradation of cellulose fibres and improve the overall quality of pulp. To overcome the disadvantages of chemical pulping. Biopulping using microorganisms, especially, fungi capable of degrading wood as well as its lignin constituent can be utilized. More often, biopulping is combined with chemical pulping i.e. successful fungal pretreatment of wood chips before chemical pulping improves penetration of cooking chemicals into wood chips and thus reduces the cooking time. Furthermore, the mechanical energy consumption can be also reduced by utilizing biopulping approach. Hence, application of microbial technology could be a cost effective and eco-friendly alternative in the pulp and paper industry.
