Abstract
The intention of our work is to establish the composition of the milk psycrotrophic microflora, to identify their mutual quantitative relationships, to study in detail the isolates of the species Bacillus cereus, which represents a problem also in pasteurised milk and milk products due to its characteristics of being a postpasterisation contaminator as a result of its capacity of surviving pasteurisation. Our intention is to study the formation and functioning of enterotoxins, cereolysine, bacteriocins and some other kinetic properties of isolated bacteria strains, identified by means of conventional respectively biochemical and also genetic methods.
The proteolytic activity of psychrotrophic microflora and individual isolates of species Bacillus cereus will be established by means of the method of defining the proteolytic degradation of casein. In this way a more progressive methodology of establishing the level of milk proteolysis will be introduced, which will be suitible for special and routine analyses and will provide data on technologically noxious microflora and chemical composition of milk, stored at low temperatures.
