标准范围

ISO 29981IDF 220:2010规定了一种在37℃厌氧条件下使用菌落计数技术选择性计数乳制品中推定双歧杆菌的方法。该方法适用于乳制品，例如发酵和非发酵乳、奶粉、婴儿配方和发酵剂培养物，其中这些微生物存在并存活，并且与其他乳酸菌组合。奶制品中使用的双歧杆菌通常属于以下物种:青春期双歧杆菌；B.动物亚科动物；B.动物亚科乳制品;二歧B.；B.简短；B.儿童；B.长。

ISO 29981|IDF 220:2010 specifies a method for the selective enumeration of presumptive bifidobacteria in milk products by using a colony count technique at 37 °C under anaerobic conditions.The method is applicable to milk products such as fermented and non-fermented milks, milk powders, infant formulae, and starter cultures where these microorganisms are present and viable, and in combination with other lactic acid bacteria.Bifidobacteria used in milk products usually belong to the species: Bifidobacterium adolescentis; B. animalis subsp. animalis; B. animalis subsp. lactis; B. bifidum; B. breve; B. infantis; B. longum.
