<P><B>Abstract</B></P> <P>This work evaluated sugarcane bagasse pretreatment with wood-decay fungi, producing varied patterns of biodegradation. The overall mass balance of sugars released after pretreatment and enzymatic hydrolysis indicated that a selective white-rot was necessary to provide glucose yields similar to the ones observed from leading physico-chemical pretreatment technologies. The selective white-rot <I>Ceriporiopsis subvermispora</I> was selective for lignin degradation in the lignocellulosic material, preserved most of the glucan fraction, and increased the cellulose digestibility of biotreated material. Glucose mass balances indicated that of the potential glucose of untreated bagasse, 47% was recovered as sugar-rich syrup after <I>C. subvermispora</I> biotreatment for 60days followed by enzymatic digestion of the pretreated material.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Pretreatment with <I>C. subvermispora</I> increased glucose yields from sugarcane bagasse. </LI> <LI> Selective degradation of lignin was necessary for enhanced glucose mass balances. </LI> <LI> Forty-seven percent of potential glucose was recovered after <I>C. subvermispora</I> biotreatment. </LI> <LI> The biotreatment efficiency was comparable to leading physico-chemical pretreatments. </LI> </UL> </P>
