Knowledge about the metabolism of sulfur-containing amino acids in bifidobacteria is especially limited. In this study, we tested the methionine utilization ability of several bifidobacterial strains when it was the sole available sulfur source. Although bifidobacteria have long been predominantly considered to he cysteine auxotrophs, we showed that this is not necessarily the case.BMFH Press2021-01engjournal articleNAhttp://hdl.handle.net/2115/80544https://doi.org/10.12938/bmfh.2020-0312186-6953Bioscience of Microbiota,Food And Health4018083
