Los medios utilizados fueron rojo congo para el grupo Azospirillium (Rodriguez 1982), Ashby para el grupo Azotobacter

The present study was designed to improve the parent strain of Azotobacter
vinelandii NRRL-14641 for hyper-production of alginate by random mutagenesis.
Enhanced production and partial characterization of an extracellular polysaccharide from newly isolated Azotobacter
Moreover, it is also providing shelter to many pests of crops as well as produces carbon dioxide which can intervene nitrogen fixation by Azotobacter
and Nitrosomonas present adjunct to plants thus, has detrimental effect on the fertility of soil.

Preservation of Azotobacter
chroococcum vegetative cells in dry polymers
Microorganisms belonging to the genera Pseudomonas, Bacillus, Rhizobium, Azotobacter
and Azospirillum, among others, frequently have the ability to solubilize phosphorus (Rodriguez and Fraga, 1999).
Respecto a las BFNA, se ha reportado que Azotobacter

The genus Azotobacter
, which belongs to the family Pseudomonadaceae from the subclass [gamma]-Proteobacteria, comprises seven species: Azotobacter
among others are the primary decomposers and [N.sub.2] fixing bacteria such as Azotobacter
, Rhizobium spp.
Azospirillum and Azotobacter
increase the nodulation process and which ultimately increase the yield of different legumes species [22, 23, 24, 25, 26].
