The number of viable Escherichia coli in a young, actively growing culture is decreased approximately 99.9 per cent by a 30 second exposure to 25 phig. streptomycin/ml. The injury induced by the antibiotic is only potentially lethal, however, and may be reversed by subculture within 5 minutes into fresh culture medium, NH(4)NO(3), NH(4)Cl, (NH(4))(2)HPO(4), NH(4) citrate, and NH(4) tartrate. Su...
Rhizosphere microbial communities are important for phytoremediation, plant nutrition, health and metabolism. Many factors, including plant species, pH and nutritional factors influence rhizosphere micro- biology. In this study, we analysed the effects of different forms of nitrogen on the structures of rhizosphere microbial communities of E. crassipes. Using a conventional culture method wit...
Ingestion of dietary (inorganic) nitrate elevates circulating and tissue levels of nitrite via bioconversion in the entero-salivary circulation. In addition, nitrite is a potent vasodilator in humans, an effect thought to underlie the blood pressure-lowering effects of dietary nitrate (in the form of beetroot juice) ingestion. Whether inorganic nitrate underlies these effects and whether the ef...
به منظور بررسی اثر اسمو‌پرایمینگ بر مؤلفه‌های جوانه‌زنی گندم (Triticum aestivum L.) رقم آذر 2 تحت شرایط عصاره آللوپاتیک علف هرز دم روباهی (Setaria viridis L.) آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار در آزمایشگاه بیوتکنولوژی اداره کل فنی و حرفه ای استان کرمانشاه در سال 1394 اجرا گردید. فاکتورهای تحقیق شامل محلول‌های اسمزی به عنوان فاکتور ...
Abstract Corrosion behaviour of stainless steel 347 was investigated in a molten nitrate salt (60 wt% NaNO 3 + 40 KNO ) immersion at 565 °C for up to 3000 h. A growth stratified oxide layers consisting NaFeO 2 , Fe O and 4 observed on the surface with constant gravimetric corrosion rate ~ 0.4 µm/year. The feasibility using Ni Al coatings deposited by means air plasma spray suppression investiga...
