Description

Technical Field

[0001] The utility model relates to the technical field of controlled bacteria inspection, in particular to a potassium glycyrrhizinate yellow Staphylococcus aureus controlled bacteria inspection device. Background Art

[0002] In the microbial limit test of potassium glycyrrhizinate, samples often fail to meet the standards. The quality department conducts segmented investigations on the reasons for failure. On the one hand, the production department investigates the problems in the easily contaminated links of the workshop production, and on the other hand, investigates whether there is a risk of contamination in the negative control of microorganisms and the control group of the target microorganism. The negative control is used to verify the negative results of the culture and inspection methods. If the target microorganism does not appear in the negative control group, it means that the invisible results of the culture or detection method are reliable. The final analysis of the cause showed that the negative control was a stoppered triangular bottle of pancreatic casein soy peptone liquid culture medium. The stopper was not tightly sealed, and there was a risk of sample contamination, which reduced the accuracy of the negative control group and the target microorganism group. A large amount of microbial repetitive testing was required, which increased the workload of operators. Therefore, in order to solve the above problems, we proposed a potassium glycyrrhizinate Staphylococcus aureus control bacteria inspection device. Utility Model Content
