• European Pharmacopoeia (EP) Chapters 5.1.3: Preserving Antimicrobial Activity
• United States Pharmacopeia (USP) Part <52>: Testing for Antimicrobial Efficacy
2. Total Viable Count
Control of microbiological cleanliness for batch release according to ISO 16212 and ISO 21149 standards or European Pharmacopoeia criteria.
• Quantitative Test for Mesophilic Bacteria (ISO 21149)
• Quantitative Counting for Yeasts and Fungi (ISO 16212)
3. Research and Identification of Microorganisms
