摘要
本文探究不同贮存条件和灭菌次数对平板计数琼脂培养基的影响。结果表明,平板计数琼脂培养基灭菌后在常温保存3 d、4℃保存3 d、灭菌3次的质量都符合GB 4789.28—2013要求。将实验结果运用在实际工作中能提高培养基利用率和实验的便利性。
This paper explores the effects of different storage conditions and sterilization times on plate counting agar medium.The results showed that the quality of plate count agar medium after sterilization at room temperature for 3 days,4℃for 3 days and sterilization for 3 times met the requirements of GB 4789.28—2013.The application of the experimental results in practical work can improve the utilization rate of the culture medium and the convenience of the experiment.
