Different Methods for Isolation and Preliminary Identification of Azotobacter
Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various director indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, byusing and comparing three different methods. The screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...
متن کاملTechnique for isolating phage for Azotobacter vinelandii.
An enrichment technique was developed whereby azotophage could readily be isolated after inoculation of soil sites with Azotobacter vinelandii.
متن کاملAzotobacter genomes: the genome of Azotobacter chroococcum NCIMB
The genome of the soil-dwelling heterotrophic N2-fixing Gram-negative bacterium Azotobacter chroococcum NCIMB 8003 (ATCC 4412) (Ac-8003) has been determined. It consists of 7 circular replicons totalling 5,192,291 bp comprising a circular chromosome of 4,591,803 bp and six plasmids pAcX50a, b, c, d, e, f of 10,435 bp, 13,852, 62,783, 69,713, 132,724, and 311,724 bp respectively. The chromosome ...
متن کاملOptimal conditions for transformation of Azotobacter vinelandii.
Optimal transformation of Azotobacter vinelandii OP required a 20-min incubation of the competent cells with deoxyribonucleic acid at 30 degrees C in buffer (pH 6.0 to 8.0) containing 8 mM magnesium sulfate. Nitrogen-fixing transformants of nitrogen fixation-deficient recipients could be plated immediately on selective medium, but transformants acquiring rifampin and streptomycin resistance req...
متن کاملGenes in Azotobacter vinelandii
Azotobacter vinelandii contains a heterodimeric, membrane-bound [NiFelhydrogenase capable of catalyzing the reversible oxidation of H2. The 13 and at subunits of the enzyme are encoded by the structural genes hoxK and hoxG, respectively, which appear to form part of an operon that contains at least one further potential gene (open reading frame 3 1ORF3]). In this study, determination of the nuc...
