METHOD FOR DETERMINING MICROBIAL CONTAMINATION |
摘要 |
The present invention discloses a process for quantitative and/ or qualitative determination of the microbial contamination of suspensions, emulsions or dispersions containing minerals and/or pigments and/or fillers and/or fiber materials wherein following the addition of one or more substances which can be degraded by microorganisms, mixing and optionally subsequent incubation a sample of the suspensions, emulsions or dispersions is centrifuged to separate the microorganisms from the minerals and/or fillers and/or pigments and/or fiber materials and the number and/or size and/or type of the microorganisms is determined in the aqueous supernatant phase after one or more incubations.
