Zinc Uptake by Lactic Acid Bacteria
The study aims to investigate zinc biosorption by strains of lactobacilli and bifidobacteria with a view to exploit them as organic matrixes for zinc dietary supplementation. Sixteen human strains of Lactobacillus and Bifidobacterium were assayed for zinc uptake. The minimum inhibitory concentration of zinc salts differed among the strains, but was never below 15 mmol L(-1). When cultured in MR...
متن کاملAntimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria
Abstract Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens. Meth...
متن کاملExopolysaccharides Production by Lactic Acid Bacteria
Exopolysaccharides (EPSs) are high molecular weight and biodegradable polymers. They are biosynthesized by a wide range of bacteria. Lactic acid bacteria (LAB) are also able to produce EPSs. EPSs can be classified into two groups. These are homopolysaccharides and heteropolysaccharides. Homopolysaccharides are polymers which are composed of one type of monosaccharide. Heteropolysaccharides are ...
متن کاملImmunomodulation by genetically engineered lactic acid bacteria.
The taxonomically diverse lactic acid bacteria (LAB) are unified by their capability to produce lactic acid from carbohydrates by fermentation. The LAB Lactococcus (L.) lactis has been characterized into great detail and is increasingly used as a production host for heterologous proteins. L. lactis is a non-pathogenic and non-colonizing LAB species and can be efficiently engineered to produce p...
متن کاملAcetaldehyde metabolism by wine lactic acid bacteria.
Acetaldehyde is a volatile flavor compound present in many fermented foods and is important in the production of red and white wines. Nine strains of the genera Lactobacillus and Oenococcus were able to metabolize acetaldehyde in a resting cell system, whereas two Pediococcus strains were not. Acetic acid and ethanol were produced from its degradation. A Lactobacillus and an Oenococcus were abl...
