conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

The effects of plant growth promoting rhizobacteria (PGPR) on the rooting and root growth of semi-hardwood and hardwood kiwifruit stem cuttings were investigated. The PGPR used were Bacillus RC23, Paenibacillus polymyxa RC05, Bacillus subtilis OSU142, Bacillus RC03, Comamonas acidovorans RC41, Bacillus megaterium RC01 and Bacillus simplex RC19. All the bacteria showed indole-3-acetic acid (IAA)...

The normal flora of laboratory mice at The Rockefeller Institute, fed on a bread and milk diet, was determined. Bacillus acidophilus and Bacillus bifidus outnumber the Bacillus coli, Bacillus acidi lactici, and Bacillus coli communior group about twenty-five to one. White and yellow cocci which may or may not liquefy gelatin are occasionally noted; spirochetal and vibrio forms and yeasts are us...

A novel bacterial strain DCY53(T) was isolated from a soil sample from a ginseng field and was characterized using a polyphasic approach. Cells were Gram-reaction-positive, rod-shaped, endospore-forming and motile with flagella. The strain was aerobic, catalase- and oxidase-positive, optimum growth temperature and pH were 30-37 °C and 6.0-7.5, respectively. On the basis of 16S rRNA gene sequenc...

an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...

background and objectives: research on xylanase has markedly increased due to its potential applications in pulping and bleaching processes using cellulose free preparations, textile processes, the enzymatic saccharification of lignocellulosic materials and waste treatment. the present study was aimed at isolation and characterization of xylan degrading strain of bacillus cereus from soil for p...

Bacillus Sp. was isolated near the mining area and was studied for biosorption U and Th. This study presents uptake of uranium (U) and thorium (Th) by live and dead cells of Bacillus Sp. Increasing concentration of U and Th showed decrease in absorption by Bacillus Sp. Dead cells of Bacillus Sp. exhibited same or more uptake of U and Th than living cells. Increasing temperature promotes uptake ...

Aiming to develop a DNA marker specific for Bacillus anthracis and able to discriminate this species from Bacillus cereus, Bacillus thuringiensis, and Bacillus mycoides, we applied the randomly amplified polymorphic DNA (RAPD) fingerprinting technique to a collection of 101 strains of the genus Bacillus, including 61 strains of the B. cereus group. An 838-bp RAPD marker (SG-850) specific for B....

The nucleotide sequences of the 3' end of the 16S rDNA and the 16S-23S internal transcribed spacer (ITS) of 40 Bacillaceae species were determined. These included 21 Bacillus, 9 Paenibacillus, 6 Brevibacillus, 2 Geobacillus, 1 Marinibacillus and 1 Virgibacillus species. Comparative sequence analysis of a 220 bp region covering a highly conserved 150 bp sequence located at the 3' end of the 16S ...

Microbial culturomics, which investigates microbial diversity by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA identification, allowed to identify five new species within the Bacillus genus. Bacillus massiliglaciei strain Marseille-P2600T, Bacillus mediterraneensis strain Marseille-P2384T, Bacillus massilinige...
