秸秆酶解脱毒工艺对异养小球藻发酵的影响
首发时间:2019-09-12
摘要:秸秆的蒸汽爆破料含有大量发酵抑制物能够抑制微生物生长、降低发酵产量,需要在酶解前去除。本文研究了不同脱毒工艺、不同洗涤工艺处理蒸汽爆破料对异养小球藻发酵结果的影响,结果发现使用水洗脱毒法处理汽爆料对异养小球藻正常生长、代谢没有明显影响,在此基础上使用多次洗涤、用水量(秸秆:水为1:9)进行脱毒,异养小球藻发酵终了干重达到9.53 g/L,仅比对照组低2.41%,能够满足使用需要。

Effect on the fermentation results of heterotrophic by detoxification technology of straw enzymatic hydrolysate
Abstract:Steam explosive material of straw contained a large number of fermentation inhibitors, which could inhibit the growth of microorganisms and reduce fermentation yield. It needed to be removed before enzymatic hydrolysis. The effects of different detoxification and washing processes on the fermentation of heterotrophic chlorella were studied in this paper. The results showed that the treatment of steam explosive by water-elution had no significant effect on the normal growth and metabolism of heterotrophic chlorella. On this basis, multiple washing and water consumption (straw: water is 1:9) were used. After detoxification, the dry weight of heterotrophic chlorella reached 9.53 g/L at the end of fermentation, which was only 2.41% lower than that of the Effect on the fermentation results of heterotrophic by detoxification technology of straw enzymatic hydrolysatecontrol group, and could meet the needs of use.
