برای بررسی امکان کنترل بیولوژیکی Fusarium oxysporum f. sp melonis عامل پژمردگی فوزاریومی خربزه سه گونه Trichoderma و دو سویه باکتری Bacillus sp. در شرایط آزمایشگاه و گلخانه مورد ارزیابی قرار گرفتتند. در آزمون کشت متقابل هم زمان جدایهT. harzianum 6 با قارچ عامل بیماری...
Bacillus sp. FJAT-27238 is a Gram-positive, spore-forming, and aerobic bacterium. Here, we report the draft genome sequence of Bacillus sp. FJAT-27238, with 6,134,829 bp, which will provide useful information for setting up phylogenomic analysis of the genomic taxonomy of Bacillus-like bacteria as well as for the functional gene mining and application of strain FJAT-27238. The genomic DNA G+C c...
Bacillus sp. PS3 produces a glycosylated flagellin. In this study, a number of the glycosylated residues of the flagellin protein were found to be located in the central variable region of this protein. We also report that the motility defect of the Bacillus subtilis flagellin mutant was complemented by Bacillus sp. PS3 flagellin variants without glycosylation, which contained amino acid substi...
Fibrinolytic enzymes have wide applications in clinical and waste treatment. Bacterial isolates were screened for fibrinolytic enzyme producing ability by skimmed milk agar plate using bromocresol green dye, fibrin plate method, zymography analysis, and goat blood clot lysis. After these sequential screenings, Bacillus sp. IND12 was selected for fibrinolytic enzyme production. Bacillus sp. IND1...
The American foulbrood disease is widely distributed all over the world and causes a serious problem for the honeybee industry. Different infected larvae were collected from different apiaries, ground in phosphate saline buffer (PSB) and bacterial isolation was carried out on nutrient agar medium. Different colonies were observed and were characterized biologically. Two bacterial isolates (SH11...
Bioaccumulation of Cd(2+) in soil bacteria might represent an important route of metal transfer to associated mycorrhizal fungi and plants and may have potential as a tool to accelerate Cd(2+) extraction in the bioremediation of contaminated soils. The present study examined the bioaccumulation of Cd(2+) in 15 bacterial strains representing three phyla (Firmicutes, Proteobacteria, and Bacteroid...
فیتیک اسید، ماده ای ضد تغذیه ای است که در دانه غلات و حبوبات یافت می شود. این ماده از جذب عناصر معدنی و پروتئین ها در روده جلوگیری کرده و ارزش غذایی ماده مصرف شده را به شدت کاهش می دهد. بنابراین استفاده از روش هایی برای کاهش و حذف این ماده راهی در جهت احیای ارزش غذایی حبوبات وغلات به شمار می آید. آنزیم فیتاز با هیدرولیز فیتیک اسید این کار را به نحوی انجام می دهد که کمترین اثر نامطلوب بر روی ماد...
Three hundred and sixty-eight strains of aerobic, endospore-forming bacteria which included type and reference cultures of Bacillus and environmental isolates were studied. Overall similarities of these strains for 118 unit characters were determined by the SSM, SJ and DP coefficients and clustering achieved using the UPGMA algorithm. Test error was within acceptable limits. Six cluster-groups ...
Plant growth promoting rhizobacteria (PGPR) are known to confer disease resistance to plants. Bacillus sp. JS demonstrated antifungal activities against five fungal pathogens in in vitro assays. To verify whether the volatiles of Bacillus sp. JS confer disease resistance, tobacco leaves pre-treated with the volatiles were damaged by the fungal pathogen, Rhizoctonia solani and oomycete Phytophth...
AIMS The aim of this study was to investigate the role of proteases in Bacillus spp. of rhizobacteria in suppressing nematode populations and to understand their mechanism of action. METHODS AND RESULTS Rhizobacteria with nematicidal activity were isolated from soil samples of five root knot nematode-infested farms. Among these strains, nematotoxicities of Bacillus strains were intensively an...
