Abstract

Totally 192 actinomycetes colonies were isolated from 18 marine sediment samples of Palk Strait region of Bay of Bengal, India. Among them, 68 isolates were morphologically distinct on the basis of colour of spore mass, reverse side colour, aerial and substrate mycelia formation, production of diffusible pigment and sporophore morphology. Thirty-nine isolates were assigned to the genus Streptomyces, Actinopolyspora (10), Saccharopolyspora (7), Actinomadura (4), Nocardiopsis (3), Micromonospora (2), Actinomyces (1), Actinoplanes (1) and Microbispora (1). From these, 64 isolates with aerial mycelia, 65 isolates with substrate mycelia and 61 isolates had both aerial and substrate mycelia.
