In order to evaluate the Effects of dual inoculation of Azotobacter and Mycorrhiza with Nitrogen and Phosphorus levels on yield and yield components of spring safflower, this study was carried out in field of Farahan university in Markazi province in 2007. A factorial in a randomized complete block design with three replications was used inoculation of Azotobacter (with inoculation and without ...

Although the terminal respiratory chain of Azotobacter has been the subject of several recent studies, the nature of the cytochrome oxidase portion is still somewhat obscure. Repaske (1) partially purified and characterized a soluble succinic dehydrogenase and succinoxidase system from Azotobacter z&elan&i. Wilson and Wilson (2) studied the soluble succinoxidase in Repaske’s preparation and dem...

This study was carried out at the forest nursery of Department of Forestry, Faculty of Agriculture and Regional Research Station, Wadura SKUAST-K, Sopore, Kashmir during 2006 and 2007 to examine the role of live biofertilizers in litter decomposition and nutrient release in Salix fragilis under natural Salix stands. The experiment was laid in completely randomised design with three replications...

During the rabi season of 2021, a field experiment was conducted in North Western plains Uttarakhand at Crop Research Centre, School Agriculture, Uttaranchal University, Dehradun to examine impact integrated nutrient management (INM) on lentil growth, yield, and economics (Lens culinaris Medik.). The laid Randomized Block Design with seven treatments i.e. T1 (Control, 100% RDF (Recommended Dose...

Cultures of Azotobacter chroococcum strain A6 were grown for 14 days in a nitrogen-deficient mineral medium, the supernatant fluid and bacteria extracted and examined by paper partition chromatography with two solvent systems which separate authentic gibberellin (GA 3) and indolyl-3-acetic acid (IAA). Gibberellin-like substances were not detected on the chromatograms examined under ultraviolet ...

We should like to thank Mr D. M. Wallace for his help in diagnosis and in arranging for the collection of specimens. This research was supported by grants to the Royal Cancer Hospital and Chester Beatty Research Institute from the British Empire Cancer Campaign, the Jane Coffin Childs Memorial Fund for Medical Research, the Anna Fuller Fund and the National Cancer Institute of the National Inst...

The 17.7 kDa R2 module from Azotobacter vinelandii mannronan C5-epimerase AlgE6 has been isotopically labeled ((13)C,(15)N) and recombinantly expressed. Here we report the (1)H, (13)C, (15)N resonance assignment of AlgE6R2.

Transformation was used to perform ratio test crosses with mutant strains of Azotobacter vinelandii unable to fix N2. Mutations that simultaneously eliminated both components of nitrogenase (nif-1 and nif-2) were tightly linked. The nif-45 mutation that resulted in the absence of an active molybdenum cofactor was closer to nif-1 and nif-2 than to any of the other nif mutations. Strains that lac...

Micrographs of freeze-cleaved Azotobacter vinelandii cysts reveal that the surface is composed of several overlapping layers. This observation is consistent with the previously proposed structure of the outer cyst coat.

The present investigation the effect of different microbial culture on growth, yield and quality Sponge Gourd (Luffa cylindrica L.) was undertaken at Vegetable Research Farm, Department Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology & Sciences, Prayagraj (UP) during 2022. experiment laid out in a Randomized Block Design with 10 tratment viz.,...
