Involvement of an N -Acetylglucosaminidase in Autolysis of Propionibacterium freudenreichii CNRZ 725
There is increasing evidence that Staphylococcus aureus may colonize the intestinal tract, especially among hospitalized patients. As Staph. aureus has been found to be associated with certain gastrointestinal diseases, it has become important to study whether this bacterium can colonize the intestinal tract and if so, whether it is possible to prevent colonization. Adhesion is the first step i...
Abstract The present study investigated the in situ production of vitamin B12 eleven cereal, pseudo-cereal and legume materials by fermentation with Propionibacterium freudenreichii DSM 20271 Levilactobacillus brevis (formerly Lactobacillus brevis) ATCC 14869. P. was used as producer L. selected to improve consistency microbial safety process. showed that more than 300 ng/g dw (daily requiremen...
The in situ production of active vitamin B12 was investigated in aqueous cereal-based matrices with three strains of food-grade Propionibacterium freudenreichii. Matrices prepared from malted barley flour (33% w/v; BM), barley flour (6%; BF), and wheat aleurone (15%; AM) were fermented. The effect of cobalt and the lower ligand 5,6-dimethylbenzimidazole (DMBI) or its natural precursors (ribofla...
