Management of sheath blight disease in rice by Pseudomonas aeruginosa MML2212
A total of 671 different isolates of FPs were isolated from rice rhizosphere soils collected from seven districts of Tamil Nadu state, India. Among them, 87 showed inhibitory activity against R. solani with the zone of inhibition ranged from 0.5 cm to 2.8 cm. Further screening was resulted in selecting an isolate, which was designated as MML2212 owing to its superior antagonistic activity against R. solani and later it was identified as Pseudomonas aeruginosa. Application of culture and culture filtrate of P. aeruginosa MML2212 increased the seed germination and other growth parameters in rice. This bacterium did not produce 2,4 diacetylphloroglucinol, pyoluteorin and pyrrolnitrin. Phenazine-1-carboxamide (PCN) was purified from culture filtrate of P. aeruginosa MML2212 and its crystal structure was elucidated.
