摘要
为了使纸质餐具中的大量纤维资源得到充分利用,采用纤维素酶对纸质餐具进行酶解,继而进一步用酵母菌进行发酵生产酒精。研究结果表明,利用纸质餐具进行纤维素酒精发酵是可行的,适宜的接种量为6%(v/v),适宜发酵时间为60h,可产生7%(v/v)的酒精含量,残余还原糖为26mg/mL。在相同的发酵条件下,经稀硫酸预处理纸质餐具发酵生产酒精含量高于未经稀硫酸处理纸质餐具,所以,稀硫酸预处理有利于纸质餐具纤维素酒精发酵。
In order to utilize cellulose of the paper-tableware, it was degraded by cellulase, and then fer-mented by microzyme. The results showed that it is feasible to produce cellulose alcohol with paper-tableware. The optimum conditions were inoculation of 6%(v/v), the fermentation time of 60 h. The alcohol yield reached to 7%(v/v) and residual reducing sugar to 26mg/mL. Under the same conditions, H2SO4 pretreatment paper-table-ware was better then no-pretreatment. H2SO4 pretreatment is profit to paper-tableware fermentation.
