Plant Growth-promoting and Bio-control Activity of Micrococcus luteus Strain AKAD 3-5 Isolated from the Soybean (Glycine max (L.) Merr.) Rhizosphere

Background: Applications of bioinoculants for improving crop productivity may be an eco-friendly alternative to chemical fertilizers. Rhizosphere or soil-inhabiting beneficial microbes can enhance plant growth and through direct indirect mechanisms, i.e. , phosphate solubilization, nutrient acquisition, phytohormone production, etc. Objective: This study is based on the hypothesis that diseases resistant plants act as a source potential have good growth-promoting traits bio-control potential. Methods: In this study, we isolated rhizobacterial strains (AKAD 2-1, AKAD 2-10, 3-5, 3-9) from rhizosphere disease-resistant variety soybean (JS-20-34) ( Glycine max (L.) Merr.). These bacterial were further screened various (phosphate indole acetic acid (IAA), ammonia, biofilm, HCN, Exopolysaccharide (EPS), enzyme production activity (catalase, cellulase, chitinase)). Results: Among four, only strain 3-5 has shown plant-growth-promoting biocontrol (98%) against Fusarium oxysporum . Morphological, biochemical, molecular characterization (16S rRNA) revealed isolate closely resembles Micrococcus luteus (Gene bank accession: MH304279). Conclusion: Here, conclude utilized promote under varied soil stress conditions.
