Zheng, Jinshui, Wittouck, Stijn, Salvetti, Elisa, Franz, Charles M.A.P., Harris, Hugh M.B., Mattarelli, Paola, O'Toole, Paul W., Pot, Bruno, Vandamme, Peter, Walter, Jens, Watanabe, Koichi, Wuyts, Sander, Felis, Giovanna E., Gänzle, Michael G., Lebeer, Sarah
The genus Lactobacillus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and genotypic levels. This study evaluated the taxonomy of Lactobacillaceae and Leuconostocaceae on the basis of whole genome sequences. Parameters that were evaluated included core...

Antimicrobial plant secondary metabolites, MDR transporters and antimicrobial resistance in cereal-associated lactobacilli: is there a connection?
Download2022-04-01
Pswarayi, Felicitas, Qiao, Nanzhen, Guar, Guatam, Gänzle, Michael
Cereal-associated lactobacilli resist antimicrobial plant secondary metabolites. This study aimed to identify multi-drug-resistance (MDR) transporters in isolates from mahewu, a Zimbabwean fermented cereal beverage, and to determine whether these MDR-transporters relate to resistance against...

Differences in whole blood gene expression associated with infection time-course and extent of fetal mortality in a reproductive model of type 2 porcine reproductive and respiratory syndrome virus (PRRSV) infection
Download2016
Ladinig, Andrea, Stothard, Paul, Wilkinson, Jamie M., Kommadath, Arun, Plastow, Graham S., Harding, John C. S., Bao, Hua, Lunney, Joan K.
Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnant females causes fetal death and increased piglet mortality, but there is substantial variation in the extent of reproductive pathology between individual dams. This study used RNA-sequencing to characterize the whole...

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...

Food fermentations for improved digestibility of plant foods - an essential ex situ digestion step in agricultural societies?
Download2021-01-05
The fermentation of plant foods detoxifies and eliminates compounds that are inherently present in grains and legumes and have antinutritive properties, including cyanogenic glycosides, vicine and convicine, phytate, phenolic compounds, immune-reactive proteins and fermentable oligosaccharides,...

Functional characterization of sucrose phosphorylase and scrR, a regulator of sucrose metabolism in Lactobacillus reuteri
Download2013-01-01
Teixeira, Januana S., Abdi, Reihaneh, Su, Marcia Shu-Wei, Schwab, Clarissa, Gänzle, Michael G.
Lactobacillus reuteri harbours alternative enzymes for sucrose metabolism, sucrose phosphorylase, fructansucrases, and glucansucrases. Sucrose phosphorylase and fructansucrases additionally contribute to raffinose metabolism. Glucansucrases and fructansucrases produce exopolysaccharides as...

Host-adapted lactobacilli in food fermentations: impact of metabolic traits of host adapted lactobacilli on food quality and human health
Download2020-10-27
Back-slopping of fermentation cultures in food fermentations can ensure stability of fermentation microbiota at the species or even at the strain level over extended periods of time. In contrast to the fermentation organisms in spontaneous food fermentations, which are derived from...

Intravaginal lactic acid bacteria modulated local and systemic immune responses and lowered the incidence of uterine infections in periparturient dairy cows
Download2015
Dunn, Suzanna M., Odhiambo, John F., Farooq, Umar, Ametaj, Burim N., Lam, Tran, Deng, Qilan
The objective of this investigation was to evaluate whether intravaginal infusion of a lactic acid bacteria (LAB) cocktail around parturition could influence the immune response, incidence rate of uterine infections, and the overall health status of periparturient dairy cows. One hundred pregnant...

Lactobacillus reuteri maintains a functional mucosal barrier during DSS treatment despite mucus layer dysfunction
Download2012
Rang, Sara, Roos, Stefan, Phillipson, Mia, Holm, Lena, Dicksved, Johan, Willing, Ben P., Petersson, Joel, Schreiber, Olof
Treatment with the probiotic bacterium Lactobacillus reuteri has been shown to prevent dextran sodium sulfate (DSS)-induced colitis in rats. This is partly due to reduced P-selectin-dependent leukocyte- and platelet-endothelial cell interactions, however, the mechanism behind this protective...

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...
