bacteriological test system and procedure for pavisande of smorsyrabakterier in milk

摘要

Bacteriological testset for establishing the occurrence of butyric acid bacterial (Clostridium) in milk, comprising a sealed, by autoclaving sterilized vial containing a sterilized culture medium for anaerobic and microaerophilic cultivating, and an against the culture medium inert compound, solidifying at a temperature below about 40 DEG C., having a density lower than the density of the culture medium, into which vial the milk to be tested is introduced under aseptic conditions; a method of establishing the occurrence of butyric acid bacteria in milk by adding the milk to be tested via a plastic drain into a sealed, autoclaved vial containing a sterilized culture medium for anaerobic and microaerophilic cultivating, and an against the medium inert compound, solidifying at a temperature below about 40 DEG C., and having a density lower than the density of the culture medium; and the use of the testset for establishing the occurrence of butyric acid bacteria in milk by adding the milk to be tested through a plastic drain into a sealed, autoclaved vial containing a sterilized culture medium for anaerobic and microaerophilic cultivating, and an against the medium inert compound, solidifying at a temperature below about 40 DEG C., and having a density lower than the density of the culture medium; whereafter the vial is heated and incubated and gas formation in the sample is read off.
