The contaminant microorganism in beer brewing included mainly four categories as wild barm , bacteria , actinomyces and mold .

啤酒生产过程中的污染微生物主要有野生酵母、细菌、放线菌和霉菌四大类。

To ferment brown rice with honey , malt , salt and barm into the brown-rice leaven , study its quality .

以糙米为原料，添加蜂蜜、大麦芽、盐、酵母进行发酵制得糙米酵素，并对其品质进行分析。

Accordingly , adequate methods should be adopted for the examination of wild barm to achieve thorough understanding of contamination source and contamination degree .

要选择适当的方法进行野生酵母的检查，了解污染的来源和程度；

In this paper , the application of genetic engineering in the improvement of beer barm was introduced and its application foreground was described .

简述了基因工程在啤酒酵母改良上的应用和展望。

The extracted RNA from cast off barm of beer was analyzed by catalytic spectrophotometry with CuO as catalyst , which reduces inference of DNA .

本文介绍了用CuO作催化剂，催化分光光度测定啤酒废酵母中RNA。在地衣酚试剂中加入CuO催化剂，可显著地减少DNA的干扰。
