Fifty cyanobacterial strains from different habitats(symbioses, soil, fresh and marine waters) belongingto the genus Nostoc were cultured and tested forbioactivity. Thirty-seven strains were isolated in ourlaboratory, the remaining were supplied by officialculture collections. All the organisms were grownunder controlled laboratory conditions. The biomasseswere lyophilised and extracted with ethanol:water toobtain a hydrophilic extract and then withdichloromethane:isopropanol to obtain a… CONTINUE READING
