This stage elucidate the changes in the microbial society (especially Streptomyces microorganisms) at the saline lands (rhizospheric and non-rhizospheric), and by means of what the presence of native plants, halophytes e.g., attract few new species of Streptomyces microorganisms by conducting few important biochemical and organic tests. Plants are part of a rich environment including many and diverse microorganisms in the soil. It has existed long recognized that few of these microbes, in the way that mycorrhizal fungi or nitrogen fixing cooperative bacteria, play main roles in plant act by improving not organic nutrition. The organic activities acted by plants and microorganisms in dry and saline soil play an main role in making them blossom in these extreme environmental environments. Therefore, in this place research, four halophyte plants namely: Caroxylon imbricatum, Sporobolus ioclados, Tamarix aphylla, and Tetraena qatarensis, were preferred to investigate the features, characteristics, and projects of Streptomyces isolates in these habitats. The synthetic and physical features of soil at the study area (Al Ghariya Sabkha) told that pH levels are almost uniform and homogenous across the Sabkha; grazing between 7.7-7.9, and salinity levels were very extreme at non-rhizospheric soil as compared to the rhizospheric soils, so, all elements at the rhizospheres of the intentional plants have lower concentrations than those at the non-rhizospheric soils. Numerous types of isolates accompanying unique community characteristics and characteristics were found in the rhizospheric soil of halophytes. These judgments suggest that a abundant number of strains of Streptomyces bacteria have grew in these miniature habitats inside the canopy of these plants. The current study told a limited number of variety of this type in the non-rhizospheric soils, only four isolates at this mini-residence of the halophytes under investigation were acknowledged, these isolates showed restricted characteristics of community features that included: flying mycelium color, soluble color, reverse color, and the form of the whole community. The enzyme ventures of the isolates that have been intentional in the rhizospheric and non-rhizospheric soils have shown more changing isolates in the rhizosphere of the plants under investigation than those of non-rhizospheric soils. The adulthood of the Streptomyces isolates at these mini-residences shown a forceful antibacterial effect against the strains that were checked, including Grandam-positive (B. subtilis, S. aureus, and S. epidermidis) and Grandam-negative (E. coli). Overall, the results of this research showed that the features and characteristics of Streptomyces microorganisms explaining their biodiversity were extreme in rhizospheric soils of halophytes as compared to non-rhizospheric soils.
