    摘要: The invention concerns a process for disinfection and/or conservation and/or reduction and/or control of microbial contamination of aqueous dispersions and/or aqueous suspensions of mineral matter, providing satisfactory stability in terms of Brookfield™ viscosity for the said aqueous dispersions and/or suspensions of mineral matter. It also concerns the said aqueous dispersions and/or suspensions thus obtained, together with their uses in the mineral, paper and paint industries. Finally it concerns the end products obtained.

    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.
