Abstract: Objective To validate the determination method of microbacteria limit of Shuitiaosan powder. Methods Plate counting method was used.The method of counting bacteria and mould was validated by the recovery rates with 5 control strains.The method of checking control bacteria was validated by observing cultivation of Staphylococcus aureus and Pseudomonas aeruginosa in the test group, positive control group and negative control group in the same environment. Results The recovery rate of every trail strains was higher than 70% when centrifugal sedimentation methods were used in the counting bacteria and mould.To the examination of control bacteria, Staphylococcus aureus and Pseudomonas aeruginosa were detected by the centrifugal sedimentation methods.The tested strains were observed in the test group and in the positive control group.No strains were observed in the negative control group. Conclusion The methods are simple, feasible, reliable and can be used for the examination of microbacteria limit.
