Brevibacillus laterosporus OSY-I1 is a Gram-positive spore-forming bacterium isolated from soil. The bacterium produces brevibacillin, an antimicrobial lipopeptide effective against several drug-resistant Gram-positive bacteria. Here, we present the draft genome sequence of the strain OSY-I1 and the gene cluster responsible for the biosynthesis of brevibacillin.
This study was carried out to evaluate the antimicrobial and antioxidant activities of different extracts from aerial parts of six Salvia species including Salvia ceratophylla, Salvia chorassanica, Salvia leriifolia, Salvia macrosiphon, Salvia chloroleuca and Salvia virgata. The effect of the extracts against 3 Gram positive and 3 Gram negative bacteria was tested by the micro dilution method. ...
Phylogenetic composition of bacterial community in soil of a karst forest was analyzed by culture-independent molecular approach. The bacterial 16S rRNA gene was amplified directly from soil DNA and cloned to generate a library. After screening the clone library by RFLP, 16S rRNA genes of representative clones were sequenced and the bacterial community was analyzed phylogenetically. The 16S rRN...
Background and purpose: Measurement of DPPH free radical scavenging is a valid, accurate, and easy method with high repeatability in evaluating the in vitro antioxidant activity of plant extracts. A positive correlation is reported between antioxidant activity and antimicrobial activity. The aim of this study was to evaluate the correlation between antioxidant and antimicrobial activity of medi...
Accounting for the effect of rebar depth variation is one of the most important and challenging tasks to accurately assess the condition of reinforced concrete elements using ground penetrating radar (GPR) technique. In current practices, this task is performed on the individual basis, as for each bridge deck a unique depth correction model is derived from the GPR data collected on it. It is fo...
In 2008 a stream flow created a sinkhole near Park City, Utah, creating an irregular-shaped depression in the alluvium about 22 m long, 10 m wide and 6 m deep. The entire discharge of a nearby creek flowed into the sinkhole increasing the size of the sinkhole. A total of 10 GPR and 4 seismic refraction profiles were conducted to find lateral and vertical extensions of this sinkhole. Interpretat...
in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...
We previously reported distinct differences in the murine in vivo Ig polysaccharide (PS)-specific responses to intact Streptococcus pneumoniae compared with responses to Neisseria meningitidis and that in each case, the bacterial subcapsular domain markedly influences the Ig response to the associated PS. In light of potentially unique contributions of biochemically distinct capsular PS and/or ...
urinary stones are prevalent and corynebacterium urealyticum, a urease-positive bacteria, is a frequent urinary tract pathogen. however, the association of this organism with urinary stones is not sufficiently studied in iran. this study was carried out to determine the prevalence of c. urealyticum in patients with urinary stones referred to the urology sections of tehran university of medical ...
BAY 12-8039 is a new 8-methoxyquinolone with antibacterial activity against gram-positive bacteria which is significantly better than those of sparfloxacin or ciprofloxacin. The minimal inhibitory concentrations (MICs) for 90% of methicillin-susceptible Staphylococcus aureus and Staphylococcus epidermidis were 0.062 and 2 mg/l, respectively. The MIC90s for ciprofloxacin-resistant, methicillin-s...
