摘要
研究发现,人工窖泥中pH值偏低是其退化的主要原因。在窖泥中发现有一类微生物除了对己酸的生成起一定的作用外,更主要的是起调节pH值的作用,将这一类微生物称为M类微生物。退化窖泥中绝大部分是窖泥中M类微生物的数量及比例不合理。以M类微生物发酵泥、发酵液等为配方制作的活性优质窖泥成功地解决了人工窖泥易退化的问题。(陶然)
The research resalts indicated that comparatively low pH value was the main cause for the degeneration of manmade pit mud. A group of microbes was found in pit mud, which had positive effects on the formation of caproic acid and could adjust pH value, and such microbes named as M group microbe. Most degenerated pit mud formed because of the improper proportioning and quantity of M group microbes in pit mud. Quality active pit mud (produced by M group fermenting mud and M group fermenting liquid etc.) could be used to settle the frequent problem of manmade pit mud degeneration. (Tran. by YUE Yang)
