Synthesis of fucosyl-N-acetylglucosamine disaccharides by transfucosylation using α-L-fucosidases from Lactobacillus casei.
AlfB and AlfC α-l-fucosidases from Lactobacillus casei were used in transglycosylation reactions, and they showed high efficiency in synthesizing fucosyldisaccharides. AlfB and AlfC activities exclusively produced fucosyl-α-1,3-N-acetylglucosamine and fucosyl-α-1,6-N-acetylglucosamine, respectively. The reaction kinetics showed that AlfB can convert 23% p-nitrophenyl-α-l-fucopyranoside into fuc...
متن کاملPhenotypic differences between commercial Lactobacillus rhamnosus GG and L. rhamnosus strains recovered from blood.
The isolation of clinical isolates that are indistinguishable, by molecular methods, from the probiotic strain of Lactobacillus rhamnosus GG has been reported. We compared the virulence potential of these clinical isolates with that of the probiotic strain. It was observed that all isolates differed significantly in 1 or more phenotypic properties.

متن کاملTowards a better understanding of Lactobacillus rhamnosus GG - host interactions
Lactobacillus rhamnosus GG (LGG) is one of the most widely used probiotic strains. Various health effects are well documented including the prevention and treatment of gastro-intestinal infections and diarrhea, and stimulation of immune responses that promote vaccination or even prevent certain allergic symptoms. However, not all intervention studies could show a clinical benefit and even for t...
متن کاملEffects of Lactobacillus rhamnosus GG on saliva-derived microcosms.
OBJECTIVE The probiotic strain Lactobacillus rhamnosus GG (LGG) is shown to hamper the presence of mutans streptococci in saliva and may have positive effects on oral health. We investigated the effects of LGG on the cariogenic potential and microbial composition of saliva-derived microcosms. DESIGN Single and dual species biofilms of LGG and Streptococcus mutans, and saliva-derived microcosm...
