Characterization of the two nonidentical ArgR regulators of Tetragenococcus halophilus and their regulatory effects on arginine metabolism
Download2020-01-01
Lin, Jieting, Luo, Xiaotong, Gänzle, Michael G., Luo, Lixin
The halophilic lactic acid bacterium Tetragenococcus halophilus has been widely used in high-salinity fermentation processes of food. Previous studies have indicated that the catabolism of arginine may contribute to the osmotic stress adaptation of T. halophilus. Unusually, in the chromosome of...

Extracellular glycosyl hydrolases are uncommon in lactobacilli and include amylases and fructosidases mediating starch and fructan utilization, respectively. Extracellular arabinanases have not been described in lactobacilli. This study is aimed at identifying the function of an arabinan...

Characterization of α-Galactooligosaccharides formed via Heterologous Expression of α- 2 Galactosidases from Lactobacillus reuteri in Lactococcus lactis
Download2014-01-01
Wang, Yvonne, Black, Brenna A., Curtis, Jonathan M., Gänzle, Michael G.
α-Galacto-oligosaccharides (α-GOS) are produced by transgalactosylation reactions of α-galactosidase (α-Gal) or by conversion of raffinose family oligosaccharides by levansucrase. Similarly to β-GOS, α-GOS have the potential to mimic glycan receptors on eukaryotic cells and act as molecular...

Chemically defined diet alters the protective properties of fructo-oligosaccharides and isomalto-oligosaccharides in HLA-B27 transgenic rats

Koleva, Petya, Ketabi, Ali, Dieleman, Levinus A., Gänzle, Michael G., Valcheva, Rosica
Non-digestible oligosaccharides (NDO) were shown to reduce inflammation in experimental colitis, but it remains unclear whether microbiota changes mediate their colitis-modulating effects. This study assessed intestinal microbiota and intestinal inflammation after feeding chemically defined...

Comparative assessment of qPCR enumeration methods that discriminate between live and dead Escherichia coli O157:H7 on beef
Download2018-01-01
Laidlaw, Anna M., Gänzle, Michael G., Yang, Xianqin
Quantitative Polymerase Chain Reaction (qPCR) is a molecular method commonly used to detect and quantify bacterial DNA on food but is limited by its inability to distinguish between live and dead cell DNA. To overcome this obstacle, propidium monoazide (PMA) alone or with deoxycholate (DC) was...

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...

Composition and activity of antifungal lipopeptides produced by Bacillus spp. in daqu fermentation
Download2023-05-01
Li, Zhen, Fernandez, Kleinberg X., Vederas, John C., Gänzle, Michael G.
Daqu is a solid-state fermentation and saccharification starter for the Chinese liquor baijou. During the daqu stage, amylolytic and proteolytic enzymes are produced by Bacillus and fungi. Bacillus spp. also produce lipopeptides with a broad spectrum of antimicrobial activities but direct...

Ripari, Valery, Gänzle, Michael G.
Sourdough has traditionally been used as leavening agent in artisanal baking. The production of baked and steamed cereal products increasingly employs sourdough as baking improver to achieve improved bread quality, or to obtain “clean label” products. Sourdoughs are maintained in bakeries by...

Contribution of glutaminases to glutamine metabolism and acid resistance in Lactobacillus reuteri and other vertebrate host adapted lactobacilli
Download2020-04-01
Li, Qing, Tao, QianYing, Teixeira, Juanana S., Shu-Wei Su, Marcia, Gänzle, Michael G.
The bacterial conversion of glutamine to glutamate is catalyzed by glutamine-amidotransferases or glutaminases. Glutamine deamination contributes to the formation of the bioactive metabolites glutamate, γ-aminobutyrate (GABA) and γ-glutamyl peptides, and to acid resistance. This study aimed to...

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...
