Total thirteen Psychrophillic actinomycetes colonies were isolated from ice point region. Among these twelve are facultative psychrophile and the strain designated RH-2 is obligatory psychrophile. All the isolated Actinomycetes are morphologically distinct on the basis of pigment production, colour of spore, types of mycelium and biochemical properties. Thirteen isolates were assigned in to the genus Micromonspora (4) Streptomyces (5) Microployspora (1) Intrasporangium (1) Dactylsporangium (1) Plaromomospora (1). Among these, 12 isolates are capable to produce both aerial and substrate mycelium where the strain RH2 produce substrate mycelium only.
