摘要
该试验研究低氧发酵条件下黄孢原毛平革菌处理甘蔗髓的效果。设对照组(CK:初始pH=4,3%蔗糖,发酵15 d)、黄孢原毛平革菌组(WRF:CK+3%菌液发酵15 d)及两阶段发酵组(TS:先加3%菌液好氧7 d,再补3%蔗糖调pH=4厌氧8 d),每组3重复。结果表明,与CK组相比,WRF组和TS组的中性洗涤纤维和酸性洗涤纤维含量均显著降低(P<0.05),粗蛋白质含量显著提高(P<0.05);WRF组酸不溶木质素含量显著低于其它组(P<0.05)。WRF组的开罐pH值显著低于其它组(P<0.05),乳酸和乙酸含量显著高于其它组(P<0.05)。综上所述,WRF组可降低纤维素的含量,提高粗蛋白质、乳酸和乙酸的含量,降低开罐pH值。
This experiment studied the effect of Fusarium oxysporum on sugarcane pulp under low oxygen fermentation conditions.Set up a control group(CK:initial pH=4,3%sucrose,fermentation for 15 days),a Aspergillus flavus group(WRF:CK+3%bacterial solution fermentation for 15 days),and a two-stage fermentation group(TS:first add 3%bacterial solution aerobic for 7 days,then add 3%sucrose to adjust pH=4 anaerobic for 8 days),with 3 replicates in each group.The results showed that:Compared with the CK group,the neutral detergent fiber and acidic detergent fiber contents in the WRF group and TS group were significantly reduced(P<0.05),and the crude protein content was significantly increased(P<0.05);The acid insoluble lignin in the WRF group was significantly lower than that in other groups(P<0.05).The pH value of the WRF group was significantly lower than that of the other groups(P<0.05),and the content of lactate and acetic acid was significantly higher than that of the other groups(P<0.05).In summary,the WRF group can reduce the content of cellulose,increase the content of crude protein,lactic acid,and acetic acid,and lower the pH value when opening the can.
