Objective: To establish microbial identification technology and monitoring database in the pharmaceutical company, so as to meet the requirements of microbial traceability investigation, analysis review and regulation compliance. Methods: Microbial orientation and numerical classification identification methods were established and the applicability of the methods was verified by analysis and identification of standard strains. Moreover, the following information of the identified bacterial, including source, colony, morphology and API identification information were stored in Word or Excel files in the format of pictures. Results: Both the microbial orientation identification and numerical classification identification methods met the requirements, which could be used for microbial identification. A library of contaminating bacteria of pharmaceutical company, electronic database of microbial identification and microbial monitoring database during the drug production could be used for testing, confirming the identification information and analyzing the contaminating bacteria. Conclusion: The microbial orientation identification and numerical classification identification methods, library of contaminating bacteria, electronic database of microbial identification and microbial monitoring database in this article could provide a simple, practical and low-cost microbial identification technology, guidance and platform for establishment of library of contaminating bacteria.
