Potential of phosphate solubilising Pseudomonas as biofungicide
2011
Subhashini, D. V. | Padmaja, K.
Beneficial effects of phosphate solublising Pseudomonas isolates were studied. Out of 30 cultures of bacteria and fungi, 25 cultures solubilised 8–70% P on solid and 9–73 μg ml⁻¹ in liquid medium. These were tested for antifungal activity against Aspergillus niger, Sclerotium rolfsii, Rhizoctonia solani, Fusarium oxysporum and Pythium aphanidermatum. The cultures of Pf-1, Pf-6, Pf-8, Pf-11, T-9 and T-10 did not inhibit any of the fungi tested, whereas Pf-9 was inhibitory to all. On the basis of P-solubilisation and antifungal activity Pf-9 and T-4 were finally selected for subsequent studies and were identified as Pseudomonas spp.
