Abstract :

Water diffusible pigment producing rhizospheric bacteria was isolated and identified as Serratia nematodiphila 213C through phenotypic characters, FAME and 16S rDNA analysis. In glycerol - peptone media at 28 OC, 72 h and 180 rpm; dark red colored pigment was biosynthesized, which showed UV – Visible absorbance at λ535 and Rf of 0.9 on TLC (10 M ethyl acetate: methanol- 6:4), suggesting close similarity toward prodigiosin type of pigment. Insecticidal performance of isolated pigment on Helicoverpa armigera and Spodoptera litura showed 70 and 100 % larval mortality at 20 and 30 mgml-1 concentrations.
