Inactivation of Salmonella spp. in wheat flour by 395 nm pulsed light emitting diode (LED) treatment and the related functional and structural changes of gluten
Download2020-01-01
Du, Lihui, Prasad, Amritha Jaya, Gänzle, Michael G., Roopesh, M.S.
Salmonella spp. is one of the top foodborne pathogens associated with low-moisture foods and they exhibit significant resistance to conventional thermal treatments. UV light pulses emitted from light emitting diode (LED) has shown antimicrobial potential in high-moisture foods and water. However,...

Chen, Yuan Yao, Gänzle, Michael G.
Heat and high pressure resistant strains of Escherichia coli are a challenge to food safety. This study investigated effects of cyclopropane fatty acids (CFAs) on stress tolerance in the heat- and pressure-resistant strain E. coli AW1.7 and the sensitive strain E. coli MG1655. The role of CFAs...

Guatam, Bina, Govindan, Byju N., Gänzle, Michael G., Roopesh, M.S.
Low-moisture foods (LMF with water activity, aw < 0.85) including pet foods and black pepper powder have consistently been associated with foodborne disease caused by Salmonella enterica. Increased heat resistance and prolonged survival at low-moisture conditions, however, remain major challenges...

Koleva, Petya, Dieleman, Levinus, Sun, Xu, Gänzle, Michael G., Valcheva, Rosica
Modulation of intestinal microbiota by non-digestible carbohydrates may reduce inflammation in inflammatory bowel disease (IBD). The aim of the present study was to assess the effects of inulin and fructo-oligosaccharides (FOS) on intestinal microbiota and colitis in HLA-B27 transgenic rats, a...

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...

Lactic metabolism revisited: metabolism of lactic acid bacteria in food fermentations and food spoilage
Download2015-01-01
Sensory properties, shelf life, and safety of a majority of fermented foods are determined by the metabolic activity of food fermenting lactic acid bacteria. This communication reviews major metabolic routes of lactic acid bacteria, and indicates how metabolism is influenced by the environmental...

LC‐MS/MS quantitation of α‐amylase/trypsin inhibitor CM3 and glutathione during wheat sourdough breadmaking
Download2022-07-01
Won, Savanna, Curtis, Jonathan, Gänzle, Michael G.
Aims This study aimed to quantify α‐amylase/trypsin inhibitor (ATI) CM3 and glutathione (GSH) during wheat sourdough breadmaking. Methods and results Breads were made with two wheat cultivars and fermented with Fructilactobacillus sanfranciscensis, F. sanfranciscensis ΔgshR or Latilactobacillus...

Lethality of high-pressure carbon dioxide on Shiga toxin-producing Escherichia coli, Salmonella and surrogate organisms on beef jerky
Download2020-05-16
Schultze, Danielle M., Couto, Ricardo, Temelli, Feral, McMullen, Lynn M., Gänzle, Michael G.
Low water activity (aW) foods permit the survival of low-infectious dose pathogens including Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella enterica increases their heat resistance; therefore, alternative methods are necessary to ensure the safety of low...

Lifestyles of sourdough lactobacilli – Do they matter for microbial ecology and bread quality?
Download2018-01-01
Gänzle, Michael G., Zheng, Jinshui
Sourdough is used in production of (steamed) bread as leavening agent (type I sourdoughs) or as baking improver to enhance flavour, texture, and shelf life of bread (type II sourdoughs). The long-term propagation of sourdoughs eliminates dispersal limitation and consistently leads to sourdough...
