摘　　要：研究了自制发酵袋移动发酵白玉菇菌糠,并对其发酵过程进行分析. 结果表明,只添加乳酸菌剂发酵白玉菇菌糠,乳酸菌利用无氮浸出物转化乳酸,白玉菇菌糠pH下降;在发酵第10天,发酵效果达到最佳,乳酸菌达到5.12×107个/mL,乳酸含量0.48%,出现了浓厚的酸香味,发酵物料湿润、无霉变、无结块,适合饲喂畜禽.发酵10 d后,产生杂酸、霉变,乳酸菌大量死亡,发酵物料颜色变黑、结块,不再适合饲喂,发酵过程中菌糠pH一直降低,到pH 4.0后趋于平衡.白玉菇菌糠发酵过程中无氮浸出物、粗纤维含量有所下降,粗蛋白质含量升高,其他指标变化不明显.Self-made bag mobile fermentation on spent white Hypsizygus marmoreus substrate and analysis of fermentation process were studied. The results indicated that just lactic acid bacteria was added during the fermentation, the nitrogen free extract was turned into lactic acid and the pH decreased. At the 10th day, the fermentation effect achieve to the best, the number of lactic acid bacteria increased to 5.12 ×107 per/mL and the content of lactic acid was 0.48%. At this time, the fermentation materials was suitable for feeding livestock and poultry as it was moist, no mildew, no agglomeration, and has strong acid flavor. But after 10th day, mix acid and mildew appeared, a lot of lactic acid bacteria death, and the fermenta-tion material turn black and caking, the fermentation materials was not suitable for feeding at this point. During the fermen-tation process, pH value decreases continuously until to 4.0, the pH was stabilizing. During the fermentation of white Hyp-sizygus marmoreus substrate, the content of nitrogen free extract and crude fiber decreased, the crude protein content in-creased, while other indexes were not obvious.
