灭菌与未灭菌龙须草生物制浆比较研究

试验研究灭菌与未灭菌龙须草生物制浆过程中微生物生长及鼠李糖变化规律结果表明 ,龙须草非纤维素降解菌全发酵过程中其生长曲线符合一般微生物生长规律 ,未受到其他因素影响 ,灭菌与未灭菌龙须草发酵过程中鼠李糖浓度在龙须草纤维分散 (发酵工艺完成 )前一直增高 ,其峰值为 0 .35g/L左右 ,但灭菌龙须草发酵过程相对略长 ;应用龙须草非纤维素降解菌进行龙须草生物制浆 ,可不必对龙须草原料、自来水以及用于脱胶的设备等进行灭菌处理。

Bio-pulping comparison between sterilized and unsterilized Eulaliopsis binata

The growing law of the microorganisms and the rhamnose variation in the fermenting course of sterilized and unsterilized Eulaliopsis binata show that the general growing law of non-cellulose decomposing series bacteria of Eulaliopsis binata,T85-260 complies with that of the microorganisms and is not affected by other factors in fermenting process;rhamnose content continues to increase before the complete separation of fiber until 0.35 g/L or so;the fermenting process of sterilized Eulaliopsis binata is a little longer;there is no need to sterilize Eulaliopsis Binata,tap water,equipment,etc. in the course of biopulping.
