1,2-propanediol metabolism by heterofermentative lactobacilli in sourdough

International Journal of Food Microbiology
The conversion of lactate to 1,2-propanediol and 1,2-propanediol to propionate sustains viability and metabolic activity of stationaryphase cells of lactobacilli over weeks or even months. The pathway was described only in few lactobacilli, and factors regulating its expression remain poorly understood. This study investigated the metabolic pathways of

Contribution of the Cpx envelope stress system to metabolism and virulence regulation in Salmonella enterica serovar Typhimurium.

PLoS ONE, 2019
The Cpx-envelope stress system regulates the expression of virulence factors in many Gram-negative pathogens. In Salmonella enterica serovar Typhimurium deletion of the sensor kinase CpxA but not of the response regulator CpxR results in the down ...
