摘要
针对环境微生物的侵染是造成茎秆糖分损失的状况,提出"抑菌-厌氧"贮存法,考察厌氧条件下两种抑菌剂(山梨酸钾和脱氢醋酸钠)对不同气候条件甜高粱茎秆贮藏效果的影响。结果表明,最优的"抑菌-厌氧"贮存法6个月茎秆糖分损失率为5.95%,无需复水便可进行固态发酵,且乙醇发酵总糖转化率在93.43%以上。
The preservation of sugars dustrialization of sweet sorghum talks in sweet sorghum stalks is one of the as a feedstock of fuel ethanol. The key blocks on the way to realize the in- ＂antiseptic and anaerobic＂ method for sweet sorghum stalks storage was proposed and validated. Two kinds of antiseptics （ potassium sorbate and sodium dehydroacetate） were investigated during the anaerobic storage of sorghum stalks at different conditions. The sugar and water contents in sweet sorghum stalks can be maintained effectively by using ＂antiseptic-anaerobic＂ storage. The sugar loss rate is less than 5.95% after 6 months, and the sugar conversion rate is above 93.43%.
