查询词典 powder process

The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.

基本营养物质的初步筛选试验证明：大米粉、豆饼粉、麦麸、酵母粉和CaCO3及KH2PO4是发酵培养基中最佳的营养物质，可满足抗菌物质产生对碳、氮和矿物质的营养需求。B-903的发酵过程可分为两个阶段：在30℃下，24小时内，细菌数量达最大值，pH值由低向高变化，但此阶段检测不出抗菌物质的活性；第二阶段，培养41小时后，抗菌物质活性开始显露，至112小时后达最大值，pH值也逐渐由高变低。
