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...

Gaur, Gautam, Damm, Sandra, Passon, Maike, Lo, Hiu Kwan, Schieber Andreas, Gänzle, Michael G.
The conversion of phenolic compounds by lactobacilli in food fermentations contributes to food quality. The metabolism of phenolics by lactobacilli has been elucidated in the past years but information on the contribution of specific enzymes in food fermentations remains scarce. This study aimed...

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...

Development of gluten-free breads started with chia and flaxseed sourdoughs fermented by selected lactic acid bacteria
Download2020-05-01
Maidana, Stefania Dentice, Finch, Susan, Garro, Marisa, Savoy, Graciela, Gänzle, Michael G., Vignolo, Graciela
Gluten-free baked goods are a challenge for biotechnologists and nutritionists because their low baking characteristics. Lactic acid bacteria (LAB) were identified and characterized from chia flour and spontaneously fermented sourdough. Based on techno-functional and safety properties, Weissella...

Diet and environment shape fecal bacterial microbiota composition and enteric pathogen load of grizzly bears
Download2011-01-01
Northrup, Joseph M., Cristescu, Bogdan, Schwab, Clarissa, Stenhouse, Gordon B., Gänzle, Michael G.
Background Diet and environment impact the composition of mammalian intestinal microbiota; dietary or health disturbances trigger alterations in intestinal microbiota composition and render the host susceptible to enteric pathogens. To date no long term monitoring data exist on the fecal...

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...

Background Dietary changes often accompany management of a cancer diagnosis, but how and why patients with colorectal cancer (CRC) make dietary decisions requires further investigation. Objective To learn about patients’ food-related beliefs and understand whether and why dietary changes were...

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,...
