Characterization of bacterial biome of Rice rhizosphere

Abstract

The Twelve rhizospheric bacterial isolates were obtained from soil samples collected from various regions of eastern Uttar Pradesh (Sitapur, Hardoiand Barabanki). All the isolated bacterial isolates were purified further on Nutrient agar media. The isolates were characterized on the basis of antagonism against Rhizoctonia solani indole acetic acid production, ammonia production and phosphate solubilization. The single best isolate was selected on the basis of qualitative screening of plant growth-promoting abilities. The molecular characterization of the isolated rhizobacterial strain was done by SDS-PAGE and 16s rDNA and identified as Brevibacillus strain DZQ7.
