Background: Actinomycetes have significant biosynthetic potential of secondary metabolites and promising resource for drug industry. These secondary metabolitesare diverse in biological, chemical structures and functions and the most prolific source of antimicrobial compounds. Most of these antimicrobial have beenisolated from soil-derived actinomycetes of the genus Streptomyces. The aim of thi...
Actinomycete strain SA198, isolated from a Saharan soil sample of Algeria, exhibited antimicrobial activity against Gram-positive and Gram-negative bacteria, and phytopathogenic and toxinogenic fungi. The morphological and chemotaxonomic characteristics of the strain were consistent with those of the genus Saccharothrix. Analysis of the 16S rRNA gene sequence of strain SA198 showed a similarity...
Microbial infections outbreak in aquatics are important challenges, and farmers have major difficulties dealing with microbes especially regarding their antibiotic resistance. The purpose of this study was comparative evaluating of antimicrobial activity of silver nanoparticles (Ag NPs) against one gram-positive bacteria (Bacillus spp) and a gram-negative (Vibrio harveyi). In this experimental ...
Introduction: Macromycetes are considered as new resources for medicine with various biological properties. One of the most important medicinal fungi in Iran is Phellinus conchatus. This genus contains 359 species around the world of which 12 species are reported from the north regions of Iran. Phellinus species have anticancer, antioxidant and antibacterial effects. Moreover, they have been us...
AIMS To determine the biodiversity of rhizobial strains nodulating Cicer arietinum L. in representative soils from various areas of Morocco. METHODS AND RESULTS Symbiotic traits, utilization of 49 carbohydrate sources, resistance to antibiotics and heavy metals, tolerance to salinity, to extreme temperatures and pH were studied as phenotypic markers. In addition, restriction fragment length p...
Plants with an established history of medicinal uses were tested against various microorganisms in this study. We compared the antibacterial activity of methanol, ethanol, and water extracts of three plant species, including Origanum syriacum, Thymus vulgaris, and Carica papaya, which commonly grow in open habitats or mountainous areas with well-drained soil. The methanol and ethanol extracts o...
background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...
To characterize the geographical distribution of medicago-nodulating rhizobia in western regions of Iran, 950 Sinorhizobium isolates were trapped from a combination of two local alfalfa populations (Hamedani, Nikshahri) together with a foreign cultivar ( Kodi) and soil samples from eight sites across Kurdestan, Kermanshah, Eastern Azarbayjan and Lorestan provinces. Also, a total of 45 isolates ...
objective: due to the alarming increase the incidence and prevalence of infectious diseases and increasing bacterial resistance to antibiotics need to discover new strong antimicrobial compounds is feeling.methods: in this study, the antimicrobial properties of spider silk pholcus phalangioides produced in sterile conditions against two bacteria, listeria monocytogenes and esherichia coli with ...
