Iron starvation in Bifidobacterium breve UCC2003 increases bile resistance through enhanced expression of a bile salt hydrolase

(Submitter supplied) Bifidobacterium are considered to be beneficial for human health and are classified as probiotic bacterium. They must resist many environmental stress factors in order to survive in the gastrointestinal environment including; pH, oxygen availability, bile and nutrient starvation (eg: iron or carbon). This study investigates Bifidobacterium breve UCC2003 global genome response to growth under ferrous and/or ferric iron limiting conditions. more...

Bifidobacterium breve UCC2003 employs multiple transcriptional regulators in a series of glycan-induced positive feedback loops to regulate HMO metabolism

(Submitter supplied) Regulation of carbohydrate metabolism in Bifidobacterium breve has been studied in detail for a variety of both plant and human-derived glycans, particularly in the model strain UCC2003. We have recently comprehensively elucidated the precise metabolic pathways by which the human milk oligosaccharide (HMO) components LNT, LNnT and LNB are utilized by B. breve UCC2003. However, no work has been carried out to date in identifying and understanding the regulatory mechanisms that control transcription of the genetic loci involved in these metabolic pathways. more...
