The intestinal microbiota plays a role in Salmonella-induced colitis independent of pathogen colonization
Download2011
Antunes, L. Caetano M., Gill, Navkiran, Russell, Shannon L., Finlay, B. Brett, Ferreira, Rosana B., Croxen, Matthew A., Willing, Benjamin P.
The intestinal microbiota is composed of hundreds of species of bacteria, fungi and protozoa and is critical for numerous biological processes, such as nutrient acquisition, vitamin production, and colonization resistance against bacterial pathogens. We studied the role of the intestinal...

Lactobacillus reuteri maintains a functional mucosal barrier during DSS treatment despite mucus layer dysfunction
Download2012
Rang, Sara, Roos, Stefan, Phillipson, Mia, Holm, Lena, Dicksved, Johan, Willing, Ben P., Petersson, Joel, Schreiber, Olof
Treatment with the probiotic bacterium Lactobacillus reuteri has been shown to prevent dextran sodium sulfate (DSS)-induced colitis in rats. This is partly due to reduced P-selectin-dependent leukocyte- and platelet-endothelial cell interactions, however, the mechanism behind this protective...

Inulin and fructo-oligosaccharides have divergent effects on colitis and commensal microbiota in HLA-B27 transgenic rats

Koleva, Petya, Dieleman, Levinus, Sun, Xu, Gänzle, Michael G., Valcheva, Rosica
Modulation of intestinal microbiota by non-digestible carbohydrates may reduce inflammation in inflammatory bowel disease (IBD). The aim of the present study was to assess the effects of inulin and fructo-oligosaccharides (FOS) on intestinal microbiota and colitis in HLA-B27 transgenic rats, a...

Follador, Rainer, Gänzle, Michael G.
Oligosaccharides, compounds that are composed of 2–10 monosaccharide residues, are major carbohydrate sources in habitats populated by lactobacilli. Moreover, oligosaccharide metabolism is essential for ecological fitness of lactobacilli. Disaccharide metabolism by lactobacilli is well...

Functional characterization of sucrose phosphorylase and scrR, a regulator of sucrose metabolism in Lactobacillus reuteri
Download2013-01-01
Teixeira, Januana S., Abdi, Reihaneh, Su, Marcia Shu-Wei, Schwab, Clarissa, Gänzle, Michael G.
Lactobacillus reuteri harbours alternative enzymes for sucrose metabolism, sucrose phosphorylase, fructansucrases, and glucansucrases. Sucrose phosphorylase and fructansucrases additionally contribute to raffinose metabolism. Glucansucrases and fructansucrases produce exopolysaccharides as...

Chemically defined diet alters the protective properties of fructo-oligosaccharides and isomalto-oligosaccharides in HLA-B27 transgenic rats
Download2014
Koleva, Petya, Ketabi, Ali, Dieleman, Levinus A., Gänzle, Michael G., Valcheva, Rosica
Non-digestible oligosaccharides (NDO) were shown to reduce inflammation in experimental colitis, but it remains unclear whether microbiota changes mediate their colitis-modulating effects. This study assessed intestinal microbiota and intestinal inflammation after feeding chemically defined...

Potential regulatory role of microRNAs in the development of bovine gastrointestinal tract during early life
Download2014
Liang, Guanxiang, Bao, Hua, Guan, Leluo, Griebel, Philip J., Stothard, Paul, McFadden, Thomas B., Malmuthuge, Nilusha
This study aimed to investigate the potential regulatory role of miRNAs in the development of gastrointestinal tract (GIT) during the early life of dairy calves. Rumen and small intestinal (mid-jejunum and ileum) tissue samples were collected from newborn (30 min after birth; n = 3), 7-day-old...

Lifestyles of sourdough lactobacilli – Do they matter for microbial ecology and bread quality?
Download2018-01-01
Gänzle, Michael G., Zheng, Jinshui
Sourdough is used in production of (steamed) bread as leavening agent (type I sourdoughs) or as baking improver to enhance flavour, texture, and shelf life of bread (type II sourdoughs). The long-term propagation of sourdoughs eliminates dispersal limitation and consistently leads to sourdough...

Exploiting synergies of sourdough and antifungal organic acids to delay fungal spoilage of bread
Download2018-01-01
Quattrini, Mattia, Liang, Nuanyi, Fortina, Maria Grazia, Xiang, Sheng, Curtis, Jonathan M., Gänzle, Michael G.
Fungal spoilage of bread remains an unsolved issue in bread making. This work aims to identify alternative strategies to conventional preservatives in order to prevent or delay fungal spoilage of bread. The minimum inhibitory concentration (MIC) of bacterial metabolites and chemical preservatives...

Ripari, Valery, Bai, Yunpeng, Gänzle, Michael G.
This work aimed to study the phenolic acid metabolism of sourdough lactic acid bacteria (LAB) in laboratory media, and in sourdough fermentation with single cultures and in co-fermentations. Lactobacilli were selected from isolates obtained from 35 sourdough samples. Isolates (114 strains) were...
