facilitating lactic acid production. Together, these findings implied that valuable lactic acid -producing bacteria can be discovered efficiently by screening under the extremely alkaline conditions ...
ABSTRACT Lactic acid bacteria (LAB) are present in foods, the environment and the animal gut, although fermented foods (FFs) are recognized as the primary niche of LAB activity. Several LAB strains ...
to hydrochloric acid (Tucker et al., 2002; Wen et al., 2003). In this report, the rapid response to an acidic environment by lactic acid , acetic acid or hydrochloric acid is termed the ‘ acid shock response ...
organic acids (OA) (acetic, citric, and lactic ) on the pathogenic bacteria is presented in Table 1. The assessment of the antimicrobial activity of the solutions of OA and that of EAS showed an important ...
will also increase. The undissociated form of lactic acid is membrane soluble, and can therefore enter the cytoplasm by simple diffusion [17]. Metabolically active bacteria maintain a pH gradient (ΔpH) where ...
to lactic , acetic, propionic, and butyric acid at several time points after treatment. Our data reveal a complex transcriptional response , with individual WOAs triggering unique gene expression profiles ...
bacteria community has been shown to counteract caries, and caries-free subjects have high levels of urease activity in plaque samples. Some lactic acid bacteria with documented probiotic behavior are urease ...
environments for the complex milieu of microbes that inhabits it, varying from acid conditions in the stomach to an alkaline pH in the small bowel. Microorganisms are also subjected to the influences of bile ...
categories: Bacillus (Gram-positive spore forming bacteria ), lactic acid –producing bacteria (Lactobacillus, Bifidobacterium, Enterococcus), and yeast (Roselli et al., 2005; Stein and Kil, 2006; NRC 2012 ...
