Mechanisms of pressure-mediated cell death and injury in Escherichia coli: From fundamentals to food applications
Download2015
High hydrostatic pressure is commercially applied to extend the shelf life of foods, and to improve food safety. Current applications operate at ambient temperature and 600 MPa or less. However, bacteria that may resist this pressure level include the pathogens Staphylococcus aureus and strains...

Follador, Rainer, Gänzle, Michael G.
Oligosaccharides, compounds that are composed of 2–10 monosaccharide residues, are major carbohydrate sources in habitats populated by lactobacilli. Moreover, oligosaccharide metabolism is essential for ecological fitness of lactobacilli. Disaccharide metabolism by lactobacilli is well...

Ripari, Valery, Bai, Yunpeng, Gänzle, Michael G.
This work aimed to study the phenolic acid metabolism of sourdough lactic acid bacteria (LAB) in laboratory media, and in sourdough fermentation with single cultures and in co-fermentations. Lactobacilli were selected from isolates obtained from 35 sourdough samples. Isolates (114 strains) were...

Novel two-component regulatory systems play a role in biofilm formation of Lactobacillus reuteri rodent isolate 100-23
Download2014-01-01
Su, Marcia Shu-Wei, Gänzle, Michael G.
his study characterized the two-component regulatory systems encoded by bfrKRT and cemAKR, and assessed their influence on biofilm formation by Lactobacillus reuteri 100-23. A method for deletion of multiple genes was employed to disrupt the genetic loci of two-component systems. The operons...

Prebiotics, FODMAPs and dietary fiber - conflicting concepts in development of functional food products?
Download2018-01-01
Yan, Ya Lu, Hu, Ying, Gänzle, Michael G.
The term prebiotic relates to beneficial modulation of intestinal microbiota by dietary carbohydrates, however, uncertainties of the differentiation of the term 'prebiotics' from dietary fiber as well as FODMAPs impede development of functional foods containing prebiotics. This communication...

This study aimed to develop an enzymatic method for conversion of chitin from fungal waste mycelia to chitooligosaccharides. The recombinant chitinase LlChi18A from Lactococcus lactis was over-expressed by Escherichia coli BL21 (DE3) and purified by affinity chromatography. The enzymatic...

Protein Recommendation to Increase Muscle (PRIMe): Study protocol for a randomized controlled pilot trial investigating the feasibility of a high protein diet to halt loss of muscle mass in patients with colorectal cancer
Download2021-02-01
Ford, Katherine L., Sawyer, Michael B., Trottier, Claire F., Ghosh, Sunita, Deutz, Nicolaas E. P., Siervo, Mario, Porter Starr, Kathryn N., Bales, Connie W., Disi, Ilana Roitman, Prado, Carla M.
Background Severe muscle mass (MM) loss is a defining feature of cancer observed across all types and stages of disease and is an independent predictor of poor clinical outcomes including higher incidences of chemotherapy toxicity and decreased survival. Protein is essential to build MM, yet the...

S., Sokol, Harry, Spector, Tim D., Surette, Michael G., Tannock, Gerald W., Walker, Alan W., Yassour, Moran, Walter, Jens
Whether the human fetus and the prenatal intrauterine environment (amniotic fluid and placenta) are stably colonized by microbial communities in a healthy pregnancy remains a subject of debate. Here we evaluate recent studies that characterized microbial populations in human fetuses from the...

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...

Zhao, Xin, Le, Minh H. A., Yang, Yan, Gänzle, Michael G., Zijlstra, Ruurd
Lactobacillus reuteri is used as probiotic culture in food and feed applications; however, strain specific properties of L. reuteri that mediate probiotic activity remain unknown. This study aimed to determine effects of feed fermentation with exopolysaccharide and reutericyclin producing L....
