Isolation, Identification and Characterization of Melanin Pigment Production in Streptomyces from Megamalai Forest Soil
Six strains among 25 streptomyces isolates produce a diffusible dark brown pigment on both peptone-yeast extract agar and streptomyces isolation agar. They also show the +ve reaction to L-tyrosine substrates. The pigment has been referred to be dark brown water soluble pigment, as melanin. The different carbon and N2 sources, which influence the pigment production in the streptomyces isolates, were also investigated. The melanin formation in the streptomyces sp is the key feature for the classification of the streptomyces group.
