摘要
本文以平板计数琼脂培养基为研究对象,通过改变灭菌后培养基的贮存条件,在满足GB 4789.28-2013培养基质量要求的前提下,摸索出提高工作效率的方法。结果表明,灭菌后的密封平板计数琼脂,可放置在55℃恒温培养箱,3d内培养基的性能可满足质量要求,从而减少培养基复溶和配制过程,满足检验的时效性需要。
In this paper,plate count agar medium was used to study,through changing the storage condition of the medium after sterilization,and on the premise of satisfying the quality requirement of GB 4789.28-2013 medium,the method of improving work efficiency was found out.The results showed that the sealed plate counting agar after sterilization could be placed in a 55℃constant temperature incubator and the properties of the medium could meet the quality requirements within 3 d,thus reducing the remelting and preparation process of the medium and meeting the need of the test.
