MC1分解木薯渣过程中可溶性物质总含量开始为18%，3 d后达到最高，为33%，GC-MS测定挥发性产物的总量在培养6 d后达到最高，挥发性产物共检测出12种，其中量较大的化合物为乙醇、乙酸、乙二醇、丁酸及甘油，这些产物为甲烷发酵菌可直接利用或者容易转化为甲烷菌直接利用的成分。

In order to improve interlayer pit mud fermentation, self-made pit mud fermenter was used and pit mud functional bacteria were supplied in each turn of fermentation. Such measures could evidently increase contact area between fermented grains and pit mud, enhance ethyl caproate content in fermented grains (enhanced by almost three times than before) with no adverse influence on liquor yield, and improve liquor quality. Its application could effectively settle the problems such as pit mud odor in liquor, difficult operation, recycle use and unsatisfactory effects etc.

采用自制夹泥发酵器和每轮补充窖泥功能菌的夹泥发酵法进行浓香型白酒生产，结果表明，该方法能明显增大糟醅接触窖泥的面积；提高糟醅中己酸乙酯等香味物质的含量，己酸乙酯的含量比对照糟醅增加了近3倍；不影响曲酒的出酒率；可明显提高曲酒的质量；有效地解决了窖泥易进入糟醅，使酒中出现明显的窖泥味、操作困难、难以循环使用、效果不明显等问题。

The growth curve of acetic acid bacteria was similar with that of yeast.

培养至第6d，发酵液中的醋酸菌的数量比菌膜中的数量高出7倍；酵母菌的数量高2倍。

In order to meet the demand of germfree production in draft beer process, the germfree measurement and the corresponding control method for fermentation temperature were studied.
