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...

Bacillus species in food fermentations: An underappreciated group of organisms for safe use in food fermentations
Download2023-04-01
Li, Zhen, Zheng, Mengzhou, Zheng, Jinshui, Gänzle, Michael G.
Fermented foods are consumed throughout the world and substantially contribute to food security. Many fermented products rely on the participation of Bacillus species, but their contribution to food quality is not well documented. The purpose of this review is to highlight metabolic properties...

Characterization of a Type‐2 Diacylglycerol Acyltransferase from Haematococcus pluvialis Reveals Possible Allostery of the Recombinant Enzyme
Download2019-12-26
Nguyen, Trinh, Xu, Yang, Abdel-Hameed, Mona, Sorensen, John L., Singer, Stacy D., Chen, Guanqun
Haematococcus pluvialis is a green microalga used in the algal biotechnology industry that can accumulate considerable amounts of storage triacylglycerol (TAG) and astaxanthin, which is a high‐value carotenoid with strong antioxidant activity, under stress conditions. Diacylglycerol...

Characterization of isogenic mutants with single or double deletions of four phenolic acid esterases in Lactiplantibacillus plantarum TMW1.460
Download2023-03-02
Gaur, Gautam, Chen, Chen, Gänzle, Michael G.
In plants, hydroxycinnamic and hydroxybenzoic acids occur mainly as esters. This study aimed to determine the contribution of individual phenolic acid esterases in Lp. plantarum TMW1.460, which encodes for four esterases: TanA, Lp0796, Est1092 and a homolog of Lj0536 and Lj1228 that was termed...

Characterization of the diversification of phospholipid:diacylglycerol acyltransferases in the green lineage
Download2020-06-15
Falarz, Lucas J., Xu, Yang, Caldo, Kristian Mark P., Garroway, Colin J., Singer, Stacy D., Chen, Guanqun
Triacylglycerols have important physiological roles in photosynthetic organisms, and are widely used as food, feed and industrial materials in our daily life. Phospholipid:diacylglycerol acyltransferase (PDAT) is the pivotal enzyme catalyzing the acyl‐CoA‐independent biosynthesis of...

Characterization of the two nonidentical ArgR regulators of Tetragenococcus halophilus and their regulatory effects on arginine metabolism
Download2020-01-01
Lin, Jieting, Luo, Xiaotong, Gänzle, Michael G., Luo, Lixin
The halophilic lactic acid bacterium Tetragenococcus halophilus has been widely used in high-salinity fermentation processes of food. Previous studies have indicated that the catabolism of arginine may contribute to the osmotic stress adaptation of T. halophilus. Unusually, in the chromosome of...
