RESUMO
A new variety of Chainia olivacea was isolated from marine sediment off Gulf of Mannar. The morphological, cultural, physiological and biochemical characters were studied, compared to known species and identified as a new variety of Chainia olivacea. Antibiotic activity of the strain was tested against both Gram positive and Gram negative bacteria as well as fungi and yeasts. Sodium chloride tolerance was also tested.

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.
