New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

Respiring Pseudomonas spp. in milk were quantified within 6 h by fluorescence in situ hybridization (FISH) with vital staining. FISH with an oligonucleotide probe based on 16S rRNA sequences was used for the specific detection of Pseudomonas spp. at the single cell level. 5-cyano-2,3-ditolyl tetrazolium chloride (CTC) was used to estimate bacterial respiratory activity. The numbers of respiring...
برخی از باکتری های بیماری زای قسمت های هوایی گیاهان، قابلیت عمل کردن به عنوان هسته یخ در دماهای 5/1 تا 9 درجه زیر صفر (5/1- تا 9-) را داشته و هر ساله خسارت های زیادی را در اثر یخ زدگی، به مزارع و باغات اکثر کشورهای دنیا وارد می سازند. تحقیق اخیر به منظور شناسایی ژن مسئول بیوسنتز پروتئین عامل یخ زدگی (ژن ice) در جدایه هایی از باکتری غالب در مرکبات و تعداد دیگری از میزبان ها در فصول خنک سال در ما...
to evaluate the effect of different application methods of different strains of pgpr on sorghum forage production, a field experiment was conducted in research farm of college of agriculture of university of tehran in karaj during 2009. the treatments were arranged factorially and the data was analyzed based on a complete block design with three replications. the treatments comprised of three p...
The main intention of this study to understand the microbial consortium of Sulphate Reducing Bacteria(SRB) and Sulphure oxidizing bacteria (SOB) on Extra polymeric substance produced by Pseudomonas sp., with combination of E-coli. In stressing the importance of anaerobic corrosion by SRB, corrosive effects of acids produced by microorganisms may be overlooked Sulphur oxidizers chiefly of the ge...
is the major bacterial disease in tomato, Background: Ralstonia solanacearum which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. R. produces several toxins helping it to invade the plant’s natural solanacearum defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used as...
Proline dehydrogenase (ProDH; 1.5.99.8) belongs to superfamily of amino acid dehydrogenase, which plays a significant role in the metabolic pathway from proline to glutamate. The goal of this research was gene cloning and characterization of ProDH enzyme from Pseudomonas fluorescens pf-5 strain. The gene encoding ProDH was isolated by means of PCR amplification and cloned in an IPTG inducible T...
Pseudomonas aeruginosa produces a number of proteases that are associated with virulence and disease progression. A substrate able to detect P. aeruginosa-specific proteolytic activity could help to rapidly alert clinicians to the virulence potential of individual P. aeruginosa strains. For this purpose we designed a set of P. aeruginosa-specific fluorogenic substrates, comprising fluorescence ...
