酒糟中纤维素的降解及再利用研究

Investigation on Degradation and Reuse of Cellulose in Distiller′s Grains

酒糟(干糟)中含有大量的纤维素,纤维素是植物细胞壁的主要成分,不易被消化,因此成为酒糟再利用进程中的一大难题。试验采用白腐菌对纤维素进行降解以降低酒糟中纤维素的含量,结果表明,纤维素降解率达到9.5%,能够提高酒糟的利用价值。

Distiller′s grains(dried)contain a lot of cellulose.The cellulose is the main component of plant cell wall and not easy to be digested,which becomes a key problem in reuse of distiller′s grains.This study was conducted to evaluate the degradation capacity of white rot fungi against the cellulose in distiller′s grains.The results showed that the cellulose degradation rate reached up to 9.5%.It is indicated that the application of white rot fungi can improve the utilization value of the distiller′s grains.
