title: Effect of chemical factors on integrated fungal fermentation of sugarcane bagasse for ethanol production by a white-rot fungus, Phlebia sp. MG-60.
abstract: Bioethanol production through integrated fungal fermentation (IFF), involving a unified process for biological delignification with consolidated biological processing by the white-rot fungus Phlebia sp. MG-60, was applied to sugarcane bagasse. Initial moisture content of the bagasse was found to affect biological delignification by MG-60, and 75% moisture content was suitable for selective lignin degradation and subsequent ethanol production. Additives, such as basal media, organic compounds, or minerals, also affected biological delignification of bagasse by MG-60. Basal medium addition improved both delignification and ethanol production. Some inorganic chemical factors, such as Fe(2+), Mn(2+), or Cu(2+), reduced bagasse carbohydrate degradation by MG-60 during delignifying incubations and resulted in increased ethanol production. The present results indicated that suitable culture conditions could significantly improve IFF efficiency.
