Which genus is characterized by these traits: gram-negative, straight or slightly curved rod, polar flagella. Among 42 isolates, 7 were single cocci, 7 coccidal chain and 4 were cocci in clumps. Azotobacter is a genus of usually motile, oval or spherical bacteria that form thick-walled cysts and may produce large quantities of capsular slime. To analyze amino acid concentration data, targeted metabolomics was implemented under supervised analysis according to fungal-bacteria interaction and time. Values of Qo2 may under favorable conditionsreach2,000inA.chroococcum (45) and even4,000 in A. tinelandii (34), the highest ob-served in anykindof lvingmatter.

Many are downloadable. These signals were similar to those given by other nitrogenase Fe proteins, as were the changes in their line shape that occurred in the presence of MgATP or MgADP. Purification and properties of the Fe protein. These strains are both academically interesting and have the potential for development as plant inoculants (4, 5) for saline soils. Zbl. Hormone production IAA All Azotobacter isolates tested were able to produce the IAA with different concentration levels. Recently, sodium-dependent A. chroococcum strains have been described (21). Azotobacter as isolated by a Dutch Scientist Beizerinchia in 1901. Azotobacter isolates ability to produce IAA marked with a color change to pink. Azotobacter chroococcum is an aerobic, free-living bacterium capable of synthesizing various plant growth-promoting substances and is useful in crop improvement for biological nitrogen-fixing activity. The Azotobacter chroococcum strain (MTCC 25045) and Trichoderma viride strain (ITCC 2211) were obtained from the germplasm of the Division of Microbiology, ICAR–Indian Agricultural Research Institute (IARI), New Delhi, and Indian Type Culture Collection (ITCC), Division of Plant Pathology, ICAR–IARI, New Delhi, India, respectively.

Azotobacter chroococcum is a bacterium discovered in 1901 by Martinus Beijerinck, noted for his discovery of an infectious agent smaller than a bacterium which is responsible for tobacco mosaic disease, as well as his role in founding the field of virology.It has the ability to fix atmospheric nitrogen, and was the first aerobic, free-living nitrogen fixer discovered. They are aerobic, free-living soil microbes which play an important role in the nitrogen cycle in nature, binding atmospheric nitrogen, which is inaccessible to plants, and releasing it in the form of ammonium ions into the soil. The genus Azotobacter is comprised of bacteria that require the presence of oxygen to grow and reproduce, and which are inhabitants of the soil. The vanadium nitrogenase of Azotobacter chroococcum. The results of gram reaction test showed that all isolates are Gram negative. The unique property of the silver nanoparticles having the antimicrobial activity drags the major attention towards the present nanotechnology. needs.
