Teixeira, Januana S., Seeras, Arisha, Sanchez-Maldonado, Alma Fernanda, Zhang, Chonggang, Su, Marcia Shu-Wei, Gänzle, Michael G.
This study aimed to determine whether glutamine deamidation improves acid resistance of Lactobacillus reuteri, and to assess whether arginine, glutamine, and glutamate-mediated acid resistance are redundant or complementary mechanisms of acid resistance. Three putative glutaminase genes, gls1,...

Glycomacropeptide from camel milk inhibits the adhesion of enterotoxigenic Escherichia coli K88 to porcine cells
Download2022-11-01
Althnaibat, Rami M., Koch, Mandy, Bruce, Heather L., Wefers, Daniel, Gänzle, Michael G.
Enterotoxigenic Escherichia coli (ETEC) are a major cause of childhood diarrhoea and of diarrhoea in piglets and calves. This study compared the anti-adhesive activities against ETEC of glycomacropeptide (GMP) from Bactrian camels and dromedaries with that of bovine GMP. GMP was purified by ion...

Host-adapted lactobacilli in food fermentations: impact of metabolic traits of host adapted lactobacilli on food quality and human health
Download2020-10-27
Back-slopping of fermentation cultures in food fermentations can ensure stability of fermentation microbiota at the species or even at the strain level over extended periods of time. In contrast to the fermentation organisms in spontaneous food fermentations, which are derived from...

Althnaibat, Rami M., Bruce, Heather L., Gänzle, Michael G.
The inhibition of starch digestion activities by peptides derived from camel milk proteins was determined and the effect of their amino acids charge and/or hydrophobicity was assessed. Starch digestion by pancreatic and brush border enzymes was assessed in vitro with a peptide to starch ratio of...

Zhao, Xin, Wang, Weilan, Blaine, Alysson, Kane, Sarah T., Zijlstra, Ruurd T., Gänzle, Michael G.
Aims: This study aimed to determine whether host-adapted lactobacilli exhibit superior survival during intestinal transit relative to nomadic and free-living organisms, and to characterize the impact of probiotic lactobacilli on autochthonous lactobacilli. Methods and Results: Mixed cultures of...

Hu, Ying, Winter, Verena, Gänzle, Michael G.
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...

Inactivation of Salmonella spp. in wheat flour by 395 nm pulsed light emitting diode (LED) treatment and the related functional and structural changes of gluten
Download2020-01-01
Du, Lihui, Prasad, Amritha Jaya, Gänzle, Michael G., Roopesh, M.S.
Salmonella spp. is one of the top foodborne pathogens associated with low-moisture foods and they exhibit significant resistance to conventional thermal treatments. UV light pulses emitted from light emitting diode (LED) has shown antimicrobial potential in high-moisture foods and water. However,...

Influence of cyclopropane fatty acids on heat, high pressure, acid, and oxidative stress resistance in Escherichia coli
Download2016-01-01
Chen, Yuan Yao, Gänzle, Michael G.
Heat and high pressure resistant strains of Escherichia coli are a challenge to food safety. This study investigated effects of cyclopropane fatty acids (CFAs) on stress tolerance in the heat- and pressure-resistant strain E. coli AW1.7 and the sensitive strain E. coli MG1655. The role of CFAs...

Influence of water activity on the heat resistance of Salmonella enterica in selected low-moisture foods
Download2020-12-01
Guatam, Bina, Govindan, Byju N., Gänzle, Michael G., Roopesh, M.S.
Low-moisture foods (LMF with water activity, aw < 0.85) including pet foods and black pepper powder have consistently been associated with foodborne disease caused by Salmonella enterica. Increased heat resistance and prolonged survival at low-moisture conditions, however, remain major challenges...

Inulin and fructo-oligosaccharides have divergent effects on colitis and commensal microbiota in HLA-B27 transgenic rats
Download2012-01-01
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...
