A taxonomic note on the genus Lactobacillus : Description of 23 novel genera, emended description of the genus Lactobacillus Beijerinck 1901, and union of Lactobacillaceae and Leuconostocaceae
Download2020-04-15
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...

Characterization of Mahewu, a Traditional Fermented Cereal Beverage from Zimbabwe, as a Source of Functional Lactobacilli
DownloadSpring 2022
Mahewu is a non-alcoholic fermented maize and finger millet malt beverage produced in Zimbabwe. Africa has a rich tradition of cereal fermentations to produce diverse products including baked goods, non-alcoholic and alcoholic beverages with live microbiota and the widespread use of fermented...

Contribution of glutaminase activity in Lactobacillus reuteri to acid resistance and glutamine metabolism in sourdough
DownloadFall 2016
Sourdough is used as an additive in bread production for proper dough volume (leavening), or for desired dough acidity, or for dough texture and bread flavor improvement, or for bread shelf life extension. Lactobacillus reuteri, an intestinal isolate and a stable member of sourdough, prevails in...

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...

Spring 2016
Sourdough fermentation can generate various peptides and amino acids to improve bread quality, such as taste, flavor and texture. The aim of this PhD dissertation was to investigate the synthesis mechanisms of bioactive and taste active peptides or amino acids during fermentation and their effect...

Degradation of Wheat Germ Agglutinin and Amylase-Trypsin Inhibitors During Sourdough Fermentation
DownloadFall 2020
Non Celiac Wheat Sensitivity (NCWS), an intolerance to the ingestion of wheat products, has increased considerably during the past few years. In sensitive individuals, NCWS manifests by intestinal and extra intestinal symptoms in different ways. Two wheat protein fractions have been linked to...

Dynamics of Enterobacteriaceae and lactobacilli in model sourdoughs are driven by pH and concentrations of sucrose and ferulic acid
Download2019-01-01
Dinardo, Francesca Rita, Minervini, Fabio, De Angelis, Maria, Gobbetti, Marco, Gänzle, Michael G.
This study aimed to assess, in model sourdough fermentations, the relevance of physico-chemical features of flour for the interactions between Enterobacteriaceae and lactobacilli, and for the interactions within the latter microbial group. Initially, model sourdoughs made with white wheat flour,...

Effect of copy number of the spoVA2mob operon, sourdough and reutericyclin on ropy bread spoilage caused by Bacillus spp.
Download2020-10-01
Li, Zhen, Siepmann, Francieli Begnini, Tovar, Luis E. Rojas, Chen, Xiaoyan, Gänzle, Michael G.
Bacillus spp. cause ropy bread spoilage of bread, which is characterized by a rotten fruity odor, followed by discoloration and degradation of the crumb. Bacillus spp. are wheat grain endophytes and form heat resistant endospores, therefore, process hygiene and heating during baking do not...
