Biological Pretreatment Technology-A Future Key for Bioethanol Production

Non-renewable fossil fuels and their continuous depletion give rise to the convergence of researchers interest towards renewable and sustainable development of bioethanol production. The present study investigated with the production of ethanol from agricultural waste such as banana pseudo stem and coir pith waste with the help of biological treatment using white rot-fungi like Pleurotus ostreatus and Phanerochaete chrysosporium carried out by SMC (Submerge) and SSC (solid state cultivation). The hydrolysis was done by Aspergillus niger, Aspergillus fumigates and mixed culture of both Aspergillus niger and Aspergillus fumigates. Finally fermentation was done by Saccharmyces cerevisiae. At SSC condition using Phanerochaete chrysosporium gives better result in case of pseudostem.
