Abstract: Apple pomace provided by Meixian branch of Hengxing Fruit Juice Co. Ltd was researched herein.Apple pomace pretreated with Trametes versicolor 500202 for different days were respectively saccharificated by cellulase,compound fungi of Trichoderma reesei RUT-C30,and Aspergillus niger UA8,and then fermented with semi-solid state. Yield of reducing sugar from pretreatment and saccharification and yield of ethanol from fermentation were determined as the function of pretreatment days. The result showed as following:( 1) with the prolonging of pretreatment days,yields of reducing sugar from saccharification of pomace with either celulase or compound fungi were both increased. Two measures reached a reducing sugar yield from sacchrification of 200. 22 g / kg and 167. 38 g / kg,respectively; a total reducing sugar content of 318. 87 g / kg and 285. 07 g / kg,respectively if pomace pretreated for 15 d.( 2) Pomace sacchrificated with compound fungi three cycles produced a total reducing sugar of 389. 09 g/kg.( 3)The yields of ethanol from the pomace saccharificated with either celulase or compound fungi were both increased with the prolong of pretreatment days and reached 201. 21 mL / kg and 180. 66 mL / kg respectively if pomace was pretreated for 15 d. With either of the two saccharification measures,total reducing sugar content and the ethanol yield from the pomace both showed a significant positive correlation( P < 0. 01).
