Antibacterial Substances from Marine Algae: Successive Extraction Using Benzene, Chloroform and Methanol

Abstract

Three different solvents viz. benzene, chloroform, and methanol have been used successively to obtain crude extracts from five different algae. These extracts were tested against both gram-positive and gram-negative bacterial strains for their antibacterial activity. The chloroform extract exhibited the greatest antibacterial activity
