Thirty six sesquiterpene lactones of the guaianolide and germacranolide-type from species of the Tribes Heliantheae and Vernonieae (Asteraceae) were evaluated for their antibacterial action. Thirty of them exhibited selective ...

A general screening for the expression of antibacterial activity and non-flocculating type of yeast strains from must and fermented broth of alcohol distilleries was performed. From 60 strains only Saccharomyces sp. M26 ...

Aim: This study evaluated the effect of light-activation on the antibacterial activity of dentin bonding systems. Methods: Inocula of Streptococcus mutans and Lactobacillus casei cultures were spread on the surface of BHI ...

Control and reduction of microorganism infections in high-risk environments is up to date a challenge. Traditional techniques imply several limitations including development of antibiotics resistance and ecotoxicity. Then, ...

Serum of mud crab, Scylla serrata has been found to possess significant antibacterial activity against some of the resident specific bacteria including Bacillus sp. N1, Bacillus flexus N3, Escherichia coli as well as ...

The mechanisms that lead to phenotypic antibacterial tolerance in bacteria remain poorly understood. We investigate whether changes in NaCl concentration toward physiologically higher values affect antibacterial efficacy ...
