Abstract
In the present investigation, a purified compound exhibiting antibacterial activity isolated in 1:1 (v/v) chloroform: methanol of red alga Portieria hornemannii collected along the coast of Pamban, Rameshwaram (Gulf of Mannar), Tamilnadu, India during Feburary 2007 was identified based on the HPLC,IR, NMR(1H &13C) spectral data. This compound is colorless crystalline nature and yield of purified compound was 53.3mg-1 Kg shade dried alga 0.00533% dry alga. The purified compound of 50 μg showed 14.3±0.56mm and 15.5±0.25mm diameter zone of inhibition, whereas 100µg of commercial antibiotic Streptomycin sulphate showed 37.6±0.56mm diameter zone of inhibiton against the test bacterium Xanthomonas axonopodies pv citri and Xanthomonas carnpestris pv malvacearum through agar diffusion technique.
