Conversion of ginsenosides by Lactobacillus plantarum studied by liquid chromatography coupled to quadrupole trap mass spectrometry
Download2015-01-01
Bai, Yunpeng, Gänzle, Michael G.
Ginsenosides are the active components responsible for the pharmacological properties of ginseng, a commonly used medicinal plant and food ingredient. This study aimed to determine the changes of ginsenosides during fermentation of ginseng extract or reference ginsenosides with Lactobacillus...

Subedi, Udaya, Ozga, Jocelyn A., Chen, Guanqun, Foroud, Nora A., Singer, Stacy D.
The demand for vegetable oils is increasing at a rapid pace due to our ever-expanding population, growing global affluence, changing dietary choices, and the need for renewable plant-derived resources. However, oilseed production is negatively impacted by unpredictable environmental conditions...

Detection of enterohaemorrhagic Escherichia coli in food by droplet digital PCR to detect simultaneous virulence factors in a single genome
Download2020-09-01
He, Li, Simpson, David, Gänzle, Michael G.
Shiga toxin producing E. coli are a problem for food producers. STEC's require a combination of virulence factors to cause disease, so ideally detection techniques should detect the presence of multiple virulence factors in a single cell directly from food. Droplet Digital PCR (ddPCR) is commonly...

Development and validation of a surrogate strain cocktail to evaluate bactericidal effects of pressure on verotoxigenic Escherichia coli
Download2015-01-01
Garcia-Hernandez, Rigoberto, McMullen, Lynn, Gänzle, Michael G.
Many strains of verotoxigenic Escherichia coli (VTEC) are highly resistant to pressure. To facilitate future studies to improve the elimination of VTEC by pressure processing of food, this study developed and validated a cocktail of non-pathogenic strains of E. coli with equal or higher...

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
Download2020-02-11
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...
