Antifungal properties of prodigiosin producing rhizospheric Serratia sp.

In the study, a pigment producing strain of Serratia sp. isolated from the rhizosphere of Bacopa monnieri (L.) was analyzed in detail for its antifungal properties and pigment production. Culture extract from the organism was found to have antifungal activity against various phytopathogens. Various cultural conditions were identified to influence the pigment production in the selected organism. Structural characterization of the pigment has confirmed it as prodigiosin. Prodigiosin producing Serratia sp. isolated in the study can be considered to have highly promising antifungal mechanisms.
