Identification of Streptococcus thermophilus CNRZ368 genes involved in defense against superoxide stress.
To better understand the defense mechanism of Streptococcus thermophilus against superoxide stress, molecular analysis of 10 menadione-sensitive mutants, obtained by insertional mutagenesis, was undertaken. This analysis allowed the identification of 10 genes that, with respect to their putative functions, were classified into five categories: (i) those involved in cell wall metabolism, (ii) th...
متن کاملEffects of Some Lamiaceae Species on NO Production and Cell Injury in Hydrogen Peroxide-induced Stress
Nitric oxide (NO) is a key mediator that plays an important role in pathogenesis of various chronic diseases like Alzheimer’s disease and Parkinson’s disease. Additionally, there is a great attitude for finding natural compounds, which could control and inhibit NO production in pathological conditions. Therefore, we were encouraged to investigate the effects of some Lamiaceae species on NO prod...

متن کاملAntibacterial action of lactoperoxidase-thiocyanate-hydrogen peroxide on Streptococcus agalactiae.
Antibacterial activity of lactoperoxidase (LP)-thiocyanate (SCN)-hydrogen peroxide (H2O2) on Streptococcus agalactiae requires that the three reactants must be in contact with the cells simultaneously. Small but assayable amounts of LP adsorb to the cell surface and are not removed by washing. A diffusible antibacterial product of LP-SCN-H2O2 reaction was not found under our experimental condit...
متن کاملStreptococcus thermophilus.
Streptocus tmophilus, as a species designation (Orla-Jensen, 1919), has included those members of the nonhemolytic streptococci that possess the unusual combination of characteristics of extreme salt sensitivity, nonobligate thermophily, a rigorous fermentative pattern with respect to certain sugars (Sherman, 1937), and, based upon attempts to culture on synthetic media, a notoriety for nutriti...
