適用范圍：This International Standard specifies a method for the enumeration of presumptive Lactobacillus acidophilusin milk products on a selective medium by using a colony-count technique at 37 °C.The method is applicable to fermented and non-fermented milks, milk powders and infant formulae wherepresumptive L. acidophilus is present and in combination with other lactic acid bacteria and bifidobacteria.The method is not applicable when the number of presumptive L. acidophilus is less than 104 CFU/g and thenumbers of Lactobacillus rhamnosus, Lactobacillus reuteri and Lactobacillus paracasei subsp. paracasei are greater than 106 CFU/g.
