Natural compounds including essential oils (EOs) are used to inhibit the pathogenic bacterial growth in foods. The objective of this study was to investigate the combined effect of Trachyspermum ammi EO and propolis ethanolic extract (PEE) on some food pathogenic bacteria. In this study, the effect of T. ammi EO and PEE at different concentrations, individually and in combinat...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
Purified and partially purified ornithine decarboxylase (ODC) from rat heart was inhibited by basic polypeptides in vitro. Poly-L-arginine, the most effective, was inhibitory at a concentration as low as 0.1 microgram/ml; protamine and histone clearly inhibited ODC at concentrations higher than 2 micrograms/ml, but poly-L-lysine was less effective. The ability to inhibit ODC appeared to correla...
We investigated the inhibitory effects of antibacterial, biocidal, and antifungal agents against Fusarium spp. Seven Fusarium spp: four F. falciforme (Fusarium solani species complex), one Fusarium spp, one Fusarium spp. (Fusarium incarnatum-equiseti species complex), and one F. napiforme (Gibberella fujikuroi species complex), isolated from eyes with fungal keratitis were used in this study. T...
Background and Purpose: Candidiasis, an important fungal infection, is considered the fourth most common nosocomial blood stream infection. Nowadays, because of increased fungal resistance to antibiotics, the use of herbal medicine has gained particular attention. Cyclamen species are medicinal plants containing triterpenoid saponins, which are shown to have antimicrobial properties. Materi...
Backgrond:Yersinia enterocolitica is zoonotic pathogen and one of important gastroenteritis agents. Some drug-resistant strains of this bacterium were discovered in the world. The use of new antibacterial compounds is one the best ways to deal with it. In this study, inhibitory effects of magnesium oxide nanoparticles, some heterocycles including thiazole, imidazolidine and tetrahydropyrimidin...
The aim of this study was to assay the antibacterial activity of Scenedesmus obtusus on some pathogenic bacteria. Microalgae S. obtusus were obtained from Algae Bank of Iran, and the methanol, ethyl acetate, chloroform and n-hexane extract of the microalgae were prepared using the maceration method. Bacterial strains were cultured in a solid culture medium, and antibacterial activity of the the...
Abstract Background and objectives: "The comb antibiotic sensitivity test" is a quick, reliable and cost effective method to determine the susceptibility of bacteria to different antibiotics. The purpose of this study is to design a plate that is easy and quick to use, and enable to be interpreted easily without the need for measurement of the margins with a ruler. Material and Method...
Background and Aim: There are some rich sources of antifungals in medicinal herbs. They have general acceptance due to their low cost and insignificant side effects. The efficacy of Peganum harmala (P. harmala) extract against Candida species was investigated in this study. Materials and Methods: In this in vitro study, we used the maceration technique to obtain P. harmala aqueous and al...
Sucrose hydrolysis was carried Out by Saccharomyces strains. The effective rate of reaction was examined experimentally for 5 different Saccharomyces strains. Two Strains of Schizosaccharomyces and Saccharomyces Carlsbergensis showed the best invertase activity. These two strains showed Michaelien Kinetics in the sucrose concentration up to 0.2 M and inhibitory effect in the concentration b...
