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...

Resistance of biofilm- and pellicle-embedded strains of Escherichia coli encoding the transmissible locus of stress tolerance (tLST) to oxidative sanitation chemicals
Download2021-12-02
Xu, Zhaohui S., Yang, Xianqin, Gänzle, Michael G.
Biofilm formation in food processing plants reduces the efficacy of sanitation. The presence of transmissible locus of stress tolerance (tLST) also enhances resistance of planktonic cells of Escherichia coli to sanitation chemicals but the role of tLST in resistance of biofilm-embedded cells...

Effect of temperature on production of oligosaccharides and dextran by Weissella cibaria 10 M
Download2018-01-01
The formation of HoPS and oligosaccharides in sourdough fermentation improves bread quality but is dependent on the expression of glycansucrases by lactic acid bacteria. Data on the expression of dextransucrases by Weissella spp., however, are limited. This study therefore aimed to assess...

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...

Ketabi, Ali, Baracos, Vickie E., Field, Catherine J., Lin, Xiaoxi, Xue, Hongyu, Bibova, Ilona, Gänzle, Michael G., Dieleman, Levinus A., Sawyer, Michael B.
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...

Antimicrobial activity of bioactive starch packaging films against Listeria monocytogenes and reconstituted meat microbiota on ham
Download2019-01-01
Zhao, Yujia, Teixeira, Januana S., Saldaña, Marleny D.A., Gänzle, Michael G.
Contamination with spoilage organisms and Listeria monocytogenes are major concerns for quality and safety of cooked ready-to-eat (RTE) meat products. Thus, the objective of this study was to investigate the use of antimicrobial starch packaging films to control competitive microbiota and L....

Comparative genomics of Lactobacillus reuteri from sourdough reveals adaptation of an intestinal symbiont to food fermentations
Download2015
Zhao, Xin, Gänzle, Michael G., Lin, Xiaoxi B., Zheng, Jinshui
Lactobacillus reuteri is a dominant member of intestinal microbiota of vertebrates, and occurs in food fermentations. The stable presence of L. reuteri in sourdough provides the opportunity to study the adaptation of vertebrate symbionts to an extra-intestinal habitat. This study evaluated this...

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...
