Identification and typing of spoilage and pathogenic microorganisms have become major objectives over the past decade in microbiology. In food, strain typing is necessary to ensure food safety and for linking cases of foodborne infections to suspected items. Recent advances in molecular biology have resulted in the development of numerous DNA-based methods for discrimination among bacterial str...

Background: Pseudomonas aeruginosa has an important role in nosocomial infections. Objective: To evaluate biological activity of the detoxified LPS (D-LPS) entrapped into Poly lactic-co-glycolic acid (PLGA) nanoparticles. Materials: LPS was extracted and detoxified from the P. aeruginosa strain PAO1. The D-LPS, conjugated to t...

Colibacillosis is known as a fatal bacterial disease resulting in a high level of commercial loss worldwide. This study amid to elucidate the sequence, genetic characteristics, and phylogeny of the bor gene in Escherichia coli (E. coli) strain c1378 (O78:K80) isolated from avian colibacillosis in Iran and develop a rapid and optimal polymerase chain reaction (PCR) mol...

In this study, Zinc Oxide nanoparticles (ZnONPs) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of Staphylococcus aureus was studied. The Zinc Oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen S.aureus. The nanoparticles size and shapes were characterized by trans...

Endosulfan contamination is one of the major concerns of soil ecosystem, which causes detrimental effects not only to humans but also to animals and plants. Therefore, the aim of this study was to isolate and identify a novel bacterial strain capable of degrading endosulfan in agriculture contaminated soils. A novel bacterial strain was isolated from the sugarcane field contaminated with endosu...

In this study, a strain of lactic acid bacteria Streptococcus salivarius was studied for its capacity to remove hexavalent chromium (Cr (VI)) from a liquid medium and to form biofilm. Both properties are useful for using the strain in bioremediation of metal-contaminated effluents. For biofilm formation capacity, three methods were used: the tube method (TM), the Congo red agar method (CRA) and...

Interactions between yeasts and lactic acid bacteria are strain specific, and their outcome is expected to change in simultaneous alcoholic--malolactic fermentations from the pattern observed in successive fermentations. One Oenococcus oeni strain Lalvin VP41™ was inoculated with two Saccharomyces cerevisiae strains either simultaneously, three days after the yeast inoculation, or when alcoholi...
