Effect of sodium chloride and chitosan on the inactivation of heat resistant or Shiga-toxin producing Escherichia coli during grilling of burger patties
Download2019-01-01
Hu, Ziyi, Rohde, Alina, McMullen, Lynn, Gänzle, Michael G.
Cattle are a reservoir for enterohemorrhagic Escherichia coli (EHEC), and ground beef is a major vehicle for human infection with EHEC. Heat resistance of E. coli, including EHEC, is impacted by NaCl and other additives. This study aimed to evaluate the effect of NaCl and other additives on the...

Effect of starter cultures on taste-active amino acids and survival of pathogenic Escherichia coli in dry fermented beef sausages
Download2018-08-01
Tang, Kai Xing, Shi, Tiange, Gänzle, Michael G.
The accumulation of taste-active compounds during ripening determines the taste of fermented meats; however, the contribution of defined starter cultures to glutamate during sausage ripening remains unknown. This study investigated the role of lactic acid bacteria and Staphylococcus carnosus on...

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...

The pressure resistance of Shiga-toxin producing Escherichia coli (STEC) depends on food matrix. This study compared the resistance of two five-strain E. coli cocktails, as well as the pressure resistant strain E. coli AW1.7, to hydrostatic pressure application in bruschetta, tzatziki, yoghurt...

Effects of high-pressure carbon dioxide on microbial quality and germination of cereal grains and beans
Download2021-09-01
Fang, Yuan, Franke, Claudia, Manthei, Alina, McMullen, Lynn, Temelli, Feral, Gänzle, Michael G.
Decontamination of low aw foods without impairing the food quality is challenging, particularly for sprouting seeds. This study aimed to explore the lethality of high pressure carbon dioxide (HPCD) to Salmonella enterica, E. coli AW1.7, A. niger, P. roquforti, and Fusarium on beans, cereal...

Environmental particulate matter induces murine intestinal inflammatory responses and alters the gut microbiome
Download2013-01-01
Thiesen, Aducio, Rioux, Kevin P., Tso, Robert, Kish, Lisa, Barkema, Herman W., Madsen, Karen L., Vincent, Renaud, Wine, Eytan, Kaplan, Gilaad G., Hotte, Naomi, Gänzle, Michael G.
Background Particulate matter (PM) is a key pollutant in ambient air that has been associated with negative health conditions in urban environments. The aim of this study was to examine the effects of orally administered PM on the gut microbiome and immune function under normal and inflammatory...

A standard level of sugar addition to bread is 2% (flour base) but sweet baked goods including hamburger buns, hot dog buns and some sandwich bread contain more than 10% sucrose. This study aimed to provide an integrated assessment of different strategies for sugar-reduced bread by using...

Evolution of sourdough microbiota in spontaneous sourdoughs started with different plant materials
Download2016-01-01
Ripari, Valery, Gänzle, Michael G., Berardi, Enrico
The preparation of sourdough in bakeries may include the use of inocula, e.g. fruits, flowers or rumen cuts to accelerate the process of selection of suitable microorganisms. The aim of this work was to investigate the effect of these inocula on the microbial evolution in sourdoughs. First, the...

Exploiting synergies of sourdough and antifungal organic acids to delay fungal spoilage of bread
Download2018-01-01
Quattrini, Mattia, Liang, Nuanyi, Fortina, Maria Grazia, Xiang, Sheng, Curtis, Jonathan M., Gänzle, Michael G.
Fungal spoilage of bread remains an unsolved issue in bread making. This work aims to identify alternative strategies to conventional preservatives in order to prevent or delay fungal spoilage of bread. The minimum inhibitory concentration (MIC) of bacterial metabolites and chemical preservatives...
