在药品卫生检验中,片状菌落的蔓延生长,严重影响中成药杂菌总数的测定结果。为此有人曾提出了一些控制办法,如用0.001%TTC肉汤琼脂培养基。该法虽能防止菌落蔓延生长成片状,但因抑制某些菌的生长,是其不足之处。亦有将培养基倾注平皿后,去盖放入干燥箱或干燥室内,烘去多余的水份再行培养。此法虽也能起到抑制片状菌落生长之效,但易造成污染。以上两法,我们多次试用皆不理想。为了进一步提高检测的准确
In the health inspection of drugs, the spread of flake-like colonies seriously affects the determination results of the total number of mixed bacteria in Chinese medicines. For this reason, some people have proposed some control methods, such as using 0.001% TTC broth agar medium. Although this method can prevent the colony from spreading and growing into flakes, it is an inadequacy due to the inhibition of the growth of certain bacteria. After pouring the culture medium into the petri dish, the lid is placed in a drying oven or a drying room, and excess water is baked to grow. Although this method can also play a role in inhibiting the growth of platelet colonies, it can easily cause pollution. The above two methods are not ideal for many trials. In order to further improve the accuracy of the test
