جهت کنترل بیولوژیکی بیماری پژمردگی آوندی میخک، ناشی از قارچ fusarium oxysporum f.sp . dianthi، اثر آنتاگونیستی 141 باکتری جدا شده از فراریشه (ریزوسفر) میخک علیه قارچ بیمارگر به روش کشت متقابل مورد بررسی قرار گرفت. از این تعداد، 16 استرین دارای خاصیت آنتاگونیستی بودند که 7 استرین با بیشترین هاله بازدارندگی برای آزمون های بعدی انتخاب شدند. بر اساس آزمون های بیوشیمیایی، فیزیولوژیکی و مرفولوژیکی اس...

گونه phaseolus vulgaris که با نام لوبیای معمولی شناخته می شود به علت محتوای بالای پروتئین (22 درصد از وزن دانه) به عنوان یکی از مهمترین لگوم ها در جهان محسوب می‏شود که مکمل غلات بوده و منبع کربوهیدرات-هاست. لوبیا به وسیله ی تعدادی از قارچ های بیماریزای گیاهی از جمله sclerotium rolfsii، عامل مرگ گیاهچه و پوسیدگی ریشه، sclerotinia sclerotiorum عامل کپک سفید ساقه و colletotrichum lindemuthianum عا...

The current study aimed to improve riboflavin production by native bacterial isolates and medium components. Bacterial species Bacillus subtilis ASU8 (KU559874) and Bacillus tequilensis ASU9 (KU559876) showed high potentiality for riboflavin production. The optimal growth and riboflavin production were achieved after 48 h. The impact of glycine addation to the basal medium was explored by apply...

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...
