摘要
A new selective antibiotic-free medium for Bifidobacterium spp. is defined. This medium has lactulose as the main carbon source and includes methylene blue, propionic acid; and lithium chloride as inhibitors of some related bacterial species. The low pH of the medium contributes to the inhibition of the growth of Enterobacteriaceae. This new selective medium has a simple composition, and the level of recovery it yields is similar to those yielded by nonselective media for Bifidobacterium strains. It: could thus be used for routine analysis in environmental or food microbiology.
