Summary. A total of 173 actinomycetes colonies were isolated from near shore marine environment and mangrove ecosystem at 8 different locations of Kerala, West Coast of India. Among them, 64 isolates were morphologically distinct on the basis of spore mass colour, reverse side colour, aerial and substrate mycelia formation and production of diffusible pigment. The majority (47%; n=30) of these isolates were assigned to the genus Streptomyces. Antimicrobial activities of isolates were also tested against various bacterial and fungal pathogens. Of 64 isolates, 21 isolates had antimicrobial activity, with 2 isolates showing broad spectrum of antimicrobial effect.

IZOLACIJA I KARAKTERIZACIJA POMORSKIH ANATAGONISTIČKIH AKTINOMICETA SA ZAPADNE OBALE INDIJE
Kratak sadržaj: Izolovano je ukupno 173 kolonija aktinomiceta sa obližnje morske obale i ekosistema mangrova na 8 različitih lokcija Kerale, na zapadnoj obali Indije. Medju njima, 64 izolata se morfološki razlikovalo prema boji spora, boji naličja, formaciji vazdušnih i micelija podloge i produkciji difuznog pigmenta. Većina (47%; n=30) izolata je pripisano rodu Streptomyces. Antimikrobna aktivnost izolata je takodje testirana na razne bakterijske i gljivične patogene. Od 64 izolata, 21 je pokazao antimikrobnu aktivnost, od kojih je 2 izolata pokazalo širok spektar antimikrobnih efekata.
