Several methods have been developed for gold exploration in the past, among which biological base method is known to be the most efficient with least expenses. This method can also be used for latent gold prospects exploration. In the present study, the possibility of applying Bacillus cereus frequency in soil as a biological marker was investigated for the exploration of latent gold prospectin...
This study investigated the bacteriological and physicochemical quality of seawater sediment samples collected from four sampling sites in Gulf Annaba (Northeastern Algeria) over a one-year period. Culture-based techniques were used to quantify assess Fecal Indicator Bacteria (FIB) potentially pathogenic bacteria. Additionally, various parameters including temperature, pH, salinity, dissolved o...
The effects of growth of two strains of lactic acid bacteria on microbial flora of ground beef after packaging in air permeable packs were studied under workshop conditions. The strains isolated from dairy products were added to ground beef at a density of 104 CFU/g after identification and antibiosis test against indicator bacteria (Escherichia coli and Staphylococcus aureus). The two strains ...
PURPOSE Azithromycin (AZI) is a new macrolide antibiotic with a better activity against intracellular gram negative bacteria in comparison with Erythromycin. The purpose of this research was to prepare AZI nanoparticles (NPs) using PLGA polymer and to compare the effectiveness of prepared nanoparticles with untreated AZI solution. METHODS AZI NPs were prepared by Modified Quasi-Emulsion Solve...
