Studies on Azotobacter Chroococcum Beij.
The study of the metabolism of Azotobacter has been generally approached from the standpoint of the r6le of this organism in the nitrogen cycle in Nature, but the fact that the ability to fix free nitrogen is regulated by the presence or absence of combined nitrogen in the medium has not been given serious attention although it is made plain in the works to be cited. Bejierink and Van Delden (1...

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 کاملThe effect of alkylresorcinol on lipid metabolism in Azotobacter chroococcum.
We studied the effect of exogenous alkylresorcinols on the lipid metabolism of Azotobacter chroococcum. We observed that when 5-n-pentadecylresorcinol was present in the growth medium, the more endogenous alkylresorcinols were synthesized. Concurrently, a drop in the amount of phospholipids was observed. These changes were associated with increasing numbers of dormant cysts, while the number of...
متن کاملInteraction of Piriformospora indica with Azotobacter chroococcum
Microbial communities in rhizosphere interact with each other and form a basis of a cumulative impact on plant growth. Rhizospheric microorganisms like Piriformospora indica and Azotobacter chroococcum are well known for their beneficial interaction with plants. These features make P. indica/A. chroococcum co-inoculation of crops most promising with respect to sustainable agriculture and to und...
