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,...

Human commensal microbiota are an important determinant of health and disease of the host. Different human body sites harbour different bacterial microbiota, bacterial communities that maintain a stable balance. However, many of the factors influencing the stabilities of bacterial communities...

Downregulation of key genes involved in carbon metabolism in Medicago truncatula results in increased lipid accumulation in vegetative tissue

Wijekoon, Champa, Singer, Stacy D., Weselake, Randall J., Petrie, James R., Chen, Guanqun, Singh, Surinder, Eastmond, Peter J., Acharya, Surya N.
Alfalfa (Medicago sativa L.) is the most widely grown perennial forage crop and is a close relative of the model diploid legume Medicago truncatula Gaertn. However, use of alfalfa leads to substantial greenhouse gas emissions and economic losses related to inefficiencies in rumen fermentation....

Dynamics of Enterobacteriaceae and lactobacilli in model sourdoughs are driven by pH and concentrations of sucrose and ferulic acid
Download2019-01-01
Dinardo, Francesca Rita, Minervini, Fabio, De Angelis, Maria, Gobbetti, Marco, Gänzle, Michael G.
This study aimed to assess, in model sourdough fermentations, the relevance of physico-chemical features of flour for the interactions between Enterobacteriaceae and lactobacilli, and for the interactions within the latter microbial group. Initially, model sourdoughs made with white wheat flour,...

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
Download2018-01-01
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 copy number of the spoVA2mob operon, sourdough and reutericyclin on ropy bread spoilage caused by Bacillus spp.
Download2020-10-01
Li, Zhen, Siepmann, Francieli Begnini, Tovar, Luis E. Rojas, Chen, Xiaoyan, Gänzle, Michael G.
Bacillus spp. cause ropy bread spoilage of bread, which is characterized by a rotten fruity odor, followed by discoloration and degradation of the crumb. Bacillus spp. are wheat grain endophytes and form heat resistant endospores, therefore, process hygiene and heating during baking do not...

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...

Effect of hydrostatic pressure and antimicrobial on survival of Listeria monocytogenes and enterohaemorrhagic E.coli in beef
Download2016-01-01
The effects of marinades on Listeria monocytogenes and enterohaemorrhagic Escherichia coli were investigated in pressure treated beef steaks. Meat was treated with 600 MPa or 450 MPa. Marinades did not enhance pressure inactivation of E. coli in beef steaks and marinades prevented...

Effect of sodium chloride and chitosan on the inactivation of heat resistant or Shiga-toxin producing Escherichia coli during grilling of burger patties

Hu, Ziyi, Rohde, Alina, McMullen, Lynn, Gänzle, Michael G.
Cattle are a reservoir for enterohemorrhagic Escherichia coli (EHEC), and ground beef is a major vehicle for human infection with EHEC. Heat resistance of E. coli, including EHEC, is impacted by NaCl and other additives. This study aimed to evaluate the effect of NaCl and other additives on the...
