“…Plant growth promoting rhizobacterial producing exo polysaccharides are highly important in promoting plant growth due to work as an active signal molecule during beneficial interactions, and provide defense response during infection process [69]. Some plant growth promoting rhizobacterial producing exo polysaccharides can also bind cations, including Na + suggesting a role in mitigation of salinity stress by reducing the content of Na + available for plant uptake [29].…”

“…Despite the fact that iron is the fourth most abundant element on earth, in aerobic soils, iron is not readily assimilated by either bacteria or plants because ferric ion or Fe +3 , which is the predominant form in nature, is only sparingly soluble so that the amount of iron available for assimilation by living organisms is extremely low [28]. Microorganisms have evolved specialized mechanisms for the assimilation of iron, including the production of low molecular weight iron-chelating compounds known as siderophores, which transport this element into their cells [29,30]. Siderophores are divided into three main families depending on the characteristic functional group, i.e.…”

Soil is dynamic living matrix and it is not only a critical resource in agricultural and food security but it is also towards maintenance of all life process. Pathogenic microorganisms affecting plant health are a major and chronic threat to sustainable agriculture and ecosystem stability worldwide. The chemical fertilizers used in the agriculture to increase yields, kill pathogens, pests, and weeds, have a big harmful impact on the ecosystem. Because of current public concerns about the side effects of agrochemicals, there is an increasing interest in improving the understanding of cooperative activities among plants and rhizosphere microbial populations. So, there is an urgent need of biological agents is accepted worldwide. The use of plant growth promoting Rhizobacteria (PGPR) is a better alternative to solve this problem. They play an important role to increase in soil fertility, plant growth promotion, and suppression of phytopathogens for development of ecofriendly sustainable agriculture. This review provides environment friendly approach to increase crop production and health, development of sustainable agriculture and commercialization by using of plant growth promoting rhizobacteria with global applicability.

Biofertilizers are relying on ecofriendly approaches as sustainability and environmental safety of agricultural for crop production. The multiplicity of beneficial effects of microbial inoculants, particularly plant growth promoters (PGP) and N2-fixing bacteria strengthened to use biofertilizers in modern agriculture. Prospection study of Enterobacter cloacae KX034162 as PGPR was carried out in this study. Based on in vivo assays for PGPRs characterization; Exopolysaccharides production (EPS), biofilm formation, Phosphate, Zinc carbonate and zinc oxide solubilization and productivity of indole acetic acid (IAA) E. cloacae KX034162 was used. The synergistic inoculation effect of two microbial on faba bean (Vicia faba L.) growth parameters and productivity were evaluated in two successful winter seasons. The results showed that the dual inoculation of both microbes have a significant positive effect on the estimated parameters compared with the control. E. cloacae KX034162 produced IAA (47.0 mgl-1), polysaccharides (6.4 gl-1) and solubilized Zn. The dual inoculation enhanced nutrients absorption, nodulation, growth parameters, N% (it was 1.42 and 1.44 in the first and second season compared with 0.29 and 0.30 as un-inoculated treatments, respectively) and at the end faba bean production increased.
