ISO 27205 | IDF 149:2010规定了工业细菌发酵剂培养物的特性，主要是乳酸菌（LAB），但也包括用于生产发酵乳制品（如酸奶、酸奶、培养黄油和奶酪）的双歧杆菌和丙酸杆菌。 ISO 27205|IDF 149:2010不适用于仅因其益生菌特性而作为食品成分添加的细菌培养物。

ISO 27205|IDF 149:2010 specifies characteristics of industrial bacterial starter cultures, which are principally lactic acid bacteria (LAB), but which also include bifidobacteria and propionibacteria used for the manufacture of fermented milk products such as yoghurt, sour cream, cultured butter and cheese. ISO 27205|IDF 149:2010 does not apply to bacterial cultures which are added as an ingredient to foods only because of their probiotic properties.
