ISO 10932-2010牛奶和乳制品.适用于双歧杆菌和非肠球菌乳酸菌(LAB)的抗生素低抑菌浓度(MIC)测定

This International Standard specifies a method for determining the minimal inhibitory concentration (MIC) of aseries of antibiotics applicable to bifidobacteria and non-enterococcal lactic acid bacteria (LAB).NOTE Unlike the disk diffusion method, which is semi-quantitative, the frequently used broth microdilution methodgives quantitative MICs of the test organism in a dilution series of the antibiotics. The lowest concentration of an antibioticthat prevents visible growth of a test organism is considered to be the MIC.This International Standard recommends the broth microdilution method as the standard method.

ISO 29981-2010奶制品.假定双歧杆菌的计算.37℃条件下的菌落计数法

This International Standard specifies a method for the selective enumeration of presumptive bifidobacteria inmilk 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, infantformulae, and starter cultures where these microorganisms are present and viable, and in combination withother lactic acid bacteria. (For proposed quality criteria of dairy products, see, for example, Codex Stan243:2003 [6].)Bifidobacteria used in milk products usually belong to the species (e.g. see References [7][8][16]):a) Bifidobacterium adolescentis;b) B. animalis subsp. animalis;c) B. animalis subsp. lactis;d) B. bifidum;e) B. breve;f) B. infantis;g) B. longum.
