Isolation and characterisation of bioactive actinomycetes from marine sediments.

Abstract

Actinomycetes (28) were isolated from marine sediments off Madras coast by plating on Starch-Casein Agar medium. After preliminary studies, five isolates which were found to be promising were selected for detailed morphological, cultural, Physiological and biochemical studies. The genera encountered were Streptomycetes. Out of these five isolates, three isolates exhibited very good broad spectrum antibacterial activity. The sodium chloride tolerance of these five isolates was also tested.
