| 摘 要： | 通过对6个微生物菌种利用棉酚能力的比较分析，筛选出对棉子饼中棉酚具有较强脱毒能力的酵母菌菌株JM-3，该菌株可降解棉子饼中80%以上的游离棉酚。研究表明JM-3的发酵适宜温度为25C，加水量与发酵底物的适宜比值为0．81(含水量45％)，适宜发酵时间为36 h。该菌种的最大优点是抗杂菌污染能力强，生长速度快，仅需36 h的发酵，就可使棉子饼粕中的棉酚含量降至0．03％以下，蛋白含量提高3个百分点以上。

| Abstract: | Comparing and analyzing on the capacity of utilizing free gossypol as carbon resource grow in 6 microbiology races, one high effective detoxification race JM-3 race selected,which can digest 80% free gossypol existing in cottonseed cakes.The study showed that the proper fermentation processing data for this race is as followstemperature 25 C, moisture 450% (watersubstrate = 0. 81),and 36 hours. The advantages of JM-3 are fast growth and resistant to contamination. It only needs 36 hours to debase free gossypol to less than 0.03%,and increase protein content 3% at least. |
