Microorganisms in the rhizosphere mediate the cycling of nutrients, their enhanced mobilisation and facilitate their uptake, leading to increased root growth, biomass and yield of plants. We examined the promise of beneficial cyanobacteria and eubacteria as microbial inoculants, applied singly or in combination as consortia or biofilms, to improve growth and yields of okra. Interrelationships a...

An experiment was carried out during two subsequent years, i.e., 2009-10 and 2010-11 to study the influence of Azotobacter, vermicompost on growth, flowering, yield and quality of strawberry cv. Chandler. There were nine treatments comprising two levels each of Azotobacter (6 and 7 kg/ha) and vermicompost (20 and 30 t/ ha) and their combinations along with one control, replicated thrice in rand...

We report the complete genome sequences of Azotobacter vinelandii mutant strain CA6 and its parent wild-type strain, CA. When fixing nitrogen, strain CA6 displays slow growth and impaired molybdate uptake, tolerance to tungstates, and production of hydrogen gas, compared to results for strain CA. Comparing these genome sequences may provide a genetic basis for these mutant phenotypes.

In 1923 a 20-year experiment was begun in an effort to gain information on the following points: (1) The factors that influence the longevity of Azotobacter when introduced into a soil from which it is normally absent; (2) the effect of introducing and maintaining an Azotobacter flora in such a soil upon the crop-producing abihty and the nitrogen balance of the soil. The recent comprehensive su...

Aims: To evaluate the effect of different nutrient management practices on growth, yield and attributes wheat.

Az átlátható veremautomata (visibly pushdown automaton) fogalmát R. Alur és P. Madhusudan vezette be 2004-ben [1]. Az „átláthatóság” azt jelenti, hogy az input betűi meghatározzák, hogy olvasásukkal egyidőben milyen veremműveletet hajt végre az automata. Egy bizonyos halmazba tartozó betűk olvasásakor az automata egy szimbólumot helyez a verembe, más betűk olvasásakor kivesz egyet, a többi betű...

The Azotobacter vinelandii is an aerobic, nitrogen-fixing bacterium with the ability to accumulate polyesters such as poly (3-hydroxybutyrate), a particular group of the polyhydroxyalkanoates (pha), when will be cultivated on several carbon sources, including sucrose. Although the capacity of Azotobacter strains to accumulate polyesters is well known, and the genes responsible for their synthes...

Azotobacter vinelandii DJ71, which contains a mutation in the nifV gene, was derepressed for nitrogenase in the presence of homocitrate. When dinitrogenase was isolated from this culture, it was found to be identical to the wild-type dinitrogenase. However, when the same NifV- strain was derepressed in the presence of erythrofluorohomocitrate, a homocitrate analog which produces a nitrogenase w...
