BdPUL12 depolymerizes β-mannan-like glycans into mannooligosaccharides and mannose, which serve as carbon sources for Bacteroides dorei and gut probiotics

Dietary manipulation of the gut microbiome in inflammatory bowel disease patients: Pilot study

“…The top bacteria favored by the IBD-AID intervention were two major butyrate producers Roseburia hominis and Faecalibacterium prautnizii 50 in CD and UC subjects, respectively (BH p-value >0.05). Two acetate producers species, Eubacterium eligens and Bacteroides dorei , 51 were enriched during intervention in both CD and UC (BH p-value >0.05); while Parabacteroides distasonis was consistently decreased in all participants regardless of disease phenotype during the intervention (BH p-value >0.05).…”

Both live and heat-killed Bifidobacterium animalis J-12 alleviated oral ulcers in LVG golden Syrian hamsters by gavage by directly intervening in the intestinal flora structure

“…56 It is also negatively correlated with SARS-CoV-2. 57 In this study, B. dorei was detected in the mouth, which is presumed to be responsible for the mobility of microorganisms in the environment. Further experiments are needed to determine whether B. dorei, a beneficial intesti-nal bacterium, can maintain its physiological activity after colonizing the mouth.…”

“…In animal experiments, mice inoculated with B. dorei are protected from in uenza infection 51 . It is also negatively correlated with SARS-CoV-2 52 . In this study, B. dorei was detected in the mouth, which is presumed to be responsible for the mobility of microorganisms in the environment.…”

Infant Gut Microbial Metagenome Mining of α- l -Fucosidases with Activity on Fucosylated Human Milk Oligosaccharides and Glycoconjugates

“…The variety of α- l -fucosidases may provide B. thetaiotaomicron species with an advantage in colonizing the gut of infants and adults ( 49 , 50 ). Other species belonging to the Bacteroidaceae family, such as B. caccae , P. vulgatus , and P. dorei , are also consistently present in the gut of newborns ( 50 ) and have been described as good consumers of dietary and host-derived glycans ( 51 , 52 ). However, until now, no α- l -fucosidase enzymes have been characterized from these species.…”
