Rhizobium sp. strain ORS571 conducts synergistic, free-living N2 fixation and nicotinate oxidation. Explicitly, ORS571 is able to fix N2 aerobically because 6-OH-nicotinate acts as an intracellular O2 sink. Because 6-OH-nicotinate oxidation is mandatory for aerobic, free-living N2 fixation and because the synergistic processes yield ammonium from substrates (as the nitrogen source for growth), ...

Bacterial strains and growth conditions. Fast-growing soybean Rhizobium strains USDA 191, USDA 192, USDA 193, USDA 194, USDA 201, USDA 205, USDA 206, USDA 208, USDA 214, USDA 217, and USDA 257 were isolated from soil or nodules collected in the PRC (20). Slow-growing soybean rhizobium strains PRC 005, PRC 74, PRC 113-2, PRC121-6, PRC 2031, and PRC B15, were oHtained from T. S. Hu, Institute of ...

in order to study the effect of different n fertilizer on berseem forage in an intercropping with basil, this experiment was conducted in research farm of college of agriculture, university of tehran during growing season 2011. experimental treatments were arranged as split plots based on a randomized complete block design with three replications. different fertilizers consisted of control (no ...

Three strains of aerobic chemoorganotrophic naphthalene-degrading bacteria (designated TSY03b(T), TSY04, and TSW01) isolated from sediment of a polychlorinated-dioxin-transforming microcosm were characterized. These strains had Gram-negative-stained, rod-shaped cells measuring 0.6‒0.9 μm in width and 1.2‒3.0 μm in length and were motile by means of peritrichous flagella. Naphthalene was utilize...

A quantitative method was developed to measure the binding of fluorescent-labeled lentil (Lens esculenta Moench), pea (Pisum sativum L.), broad bean (Vicia faba L.), and jackbean (Canavalia ensiformis L., DC.) lectins to various Rhizobium strains. Lentil lectin bound to three of the five Rhizobium leguminosarum strains tested. The number of lentil lectin molecules bound per R. leguminosarum 128...
