Digestibility of branched and linear α-gluco-oligosaccharides in vitro and in ileal-cannulated pigs
Download2020-01-01
Hu, Ying, Heyer, Charlotte M.E., Wang, Weilan, Zijlstra, Ruurd T., Gänzle, Michael G.
Isomalto-oligosaccharides (IMOs) may promote health by modulating intestinal microbiota. We hypothesized that the proportion of α–(1 → 6) linkages in IMOs determines their digestibility. Ileal-cannulated pigs were fed diets containing IMO, IMO-DP3 with a greater DP and more α-(1 → 4) linkages,...

Effect of acceptor carbohydrates on oligosaccharide and polysaccharide synthesis by dextransucrase DsrM from Weissella cibaria
Download2017-09-01
Hu, Ying, Winter, Verena, Chen, Xiao Yan, Gänzle, Michael G.
The digestibility of isomalto-oligosaccharides (IMO) as well as their metabolism by gut microbiota depends on the degree of polymerization and the ratio of α-(1→4) to α-(1→6) linkages. Both parameters are influenced by the method of production. Commercial IMO are produced by transglycosylation of...

Effect of chitosan, and bacteriocin – Producing Carnobacterium maltaromaticum on survival of Escherichia coli and Salmonella Typhimurium on beef

Hu, Zi Yi, Balay, Danielle, Hu, Ying, McMullen, Lynn M., Gänzle, Michael G.
The aim of this study was to investigate the synergistic effect of chitosan and bacteriocins against Escherichia coli and Salmonella in media and in lean beef. The inhibitory effects of chitosan and bacteriocins against E. coli AW1.7 and S. enterica Typhimurium in media were determined by a...

Effect of drying on oxidation of membrane lipids and expression of genes encoded by the Shiga toxin prophage in Escherichia coli
Download2020-01-01
Fang, Yuan, McMullen, Lynn M., Gänzle, Michael G.
Drying processes do not eliminate pathogenic Escherichia coli in foods but induce sublethal injury, which may also induce the Shiga toxin (Stx) prophage. This study investigated the effect of drying on membrane lipid oxidation and stx expression in E. coli. Lipid peroxidation was probed with...

Li, Hui, Garcia-Hernandez, Rigoberto, Driedger, Darcy, McMullen, Lynn M., Gänzle, Michael G.
The pressure resistance of Shiga-toxin producing Escherichia coli (STEC) depends on food matrix. This study compared the resistance of two five-strain E. coli cocktails, as well as the pressure resistant strain E. coli AW1.7, to hydrostatic pressure application in bruschetta, tzatziki, yoghurt...

Isomalto-oligosaccharides (IMO) significantly contribute to the global oligosaccharide market. IMO are linear α-(1 → 6) linked oligosaccharides with isomaltotriose as the representative trisaccharide. Commercial IMO preparations ypically also contain panose-series oligosaccharides as a major...

Intestinal microbiota mediate toxicity of irinotecan (CPT-11) cancer therapies and cause systemic infection after CPT-11-induced loss of barrier function. The intestinal microbiota and their functions are thus potential targets for treatment to mitigate CPT-11 toxicity. However, microbiota...

Lethality of high-pressure carbon dioxide on Shiga toxin-producing Escherichia coli, Salmonella and surrogate organisms on beef jerky
Download2020-05-16
Schultze, Danielle M., Couto, Ricardo, Temelli, Feral, McMullen, Lynn M., Gänzle, Michael G.
Low water activity (aW) foods permit the survival of low-infectious dose pathogens including Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella enterica increases their heat resistance; therefore, alternative methods are necessary to ensure the safety of low...

Prebiotics, FODMAPs and dietary fiber - conflicting concepts in development of functional food products?
Download2018-01-01
Yan, Ya Lu, Hu, Ying, Gänzle, Michael G.
The term prebiotic relates to beneficial modulation of intestinal microbiota by dietary carbohydrates, however, uncertainties of the differentiation of the term 'prebiotics' from dietary fiber as well as FODMAPs impede development of functional foods containing prebiotics. This communication...

This study aimed to develop an enzymatic method for conversion of chitin from fungal waste mycelia to chitooligosaccharides. The recombinant chitinase LlChi18A from Lactococcus lactis was over-expressed by Escherichia coli BL21 (DE3) and purified by affinity chromatography. The enzymatic...
