目前 ,各微生物实验室、细菌室对葡萄糖蛋白胨水、尿素培养基的除菌均是采用高压蒸汽灭菌法 ( 1 0磅 30ｍｉｎ灭菌 ) ,但在灭菌过程中 ,葡萄糖及尿素易破坏或分解 ,以致ＶＰ试验、尿素分解试验等出现假阴性、假阳性结果或结果难以判断 ,导致教学过程中无法导出预期的实验结论 , At present, the sterilization of glucose peptone water and urea culture medium in each microbial laboratory and bacterial room is carried out by autoclaving (sterilization of 10 pounds and 30 minutes), but in the sterilization process, glucose and urea are easily destroyed or Decomposition, resulting in VP test, urea decomposition test false negative, false positive results or results difficult to judge, resulting in the teaching process can not be derived from the expected experimental conclusion,
