N2 - Seventy-eight isolates of actinomycetes were isolated from the soil samples collected from alpine zones of Pindari glacier region in Indian Himalaya. Following a plate based rapid screening using two test fungi, five efficient isolates (nos. HA1, HA2, HA6, HA40, and HA142) were selected for further characterization with special reference to their antagonistic properties. Based on phenotypic and genotypic characters, the isolates were identified up to species level. All the isolates belonged to the genus Streptomyces. The isolate nos. HA1 and HA2 were S. sampsonii and HA6, HA40 and HA142 were S. griseobrunneus, S. aurantiacus, and S. griseoluteus, respectively. The isolates showed strong antifungal properties against phytopathogenic test fungi in plate assays. All the isolates hydrolyzed glycol-chitin as a substrate in denaturing conditions showing variable amount of different isoforms.
