Background; Feather waste is generated in large amounts as a by-product of commercial poultry processing. The main component of feather is keratin. The main purpose of this study was to identify Bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. Methods; Bacillus spp. Were isolated from the waste of poultries located in Miyaneh city. The bact...

Salinity causes disturbance in symbiotic performance of plants, and increases susceptibility of plants to soil-borne pathogens. Endophytic bacteria are an essential determinant of cross-tolerance to biotic and abiotic stresses in plants. The aim of this study was to isolate non-rhizobial endophytic bacteria from the root nodules of chickpea (Cicer arietinum L.), and to assess their ability to i...

root-lesion disease, which is caused by pratylenchus loosi , is one of the most important diseases currently impacting iran tea plantations. this disease causes great economic crop impacts. northern provinces, which supply much of iran’s tea production, have been especially hard impact by root-lesion disease.the purpose of this study was to biological control the nematodes as one of the main se...

Salmonella continues to be a major public health burden worldwide. Poultry are known to be one of the main reservoirs for this zoonotic pathogen. It has previously been shown that a single dose of Bacillus subtilis reduces fecal shedding of Salmonella enterica serovar Enteritidis, whereas no effect on long-term colonization of the cecum has been observed. Here we report experiments that were un...

The applications of zerovalent iron nanoparticles in environmental remediation have led to the development of green methods in their synthesis. This study for the first time reports on the green synthesis of zerovalent iron nanoparticles using Thuja orientalis extract as the reducing and capping agent at room temperature. The synthesized nanoparticles were characterized with different tec...

BACKGROUND Sublancin is a novel and distinct antimicrobial glycopeptide that can be used as an alternative to conventional antibiotics. The reported production of sublancin by Bacillus subtilis 168 is poor because transcriptional regulatory circuit of sunA, a gene that encodes presublancin, is complex and difficult to control. RESULTS A strong inducible and easy to control vegetative σA promo...

Background: The appearance of multi-drug resistant microorganisms is becoming a global problem. Already several strategies have been employed to overcome antibiotic resistance issue. Developing new antimicrobial compounds from microbial sources could be a beneficial solution. Hence screening programs in order to discover new antibiotics from microbial entities are interesting. Because of high c...

bruchidius fulvus allard is a biological control agent of camelthorn weed (alhagi camelorum fisch.) in birjand region. efficiency of b. fulvus for biological control of camelthorn weed was studied by separate experiments in laboratory and natural conditions based on crd in 2009. so in average, 35±1.15 and 48±1.04% of the seeds in the legumes destroyed in the spring sampling (early of may) and i...
