| Abstract | ||
| In present study, some physical and chemical parameters are measured for the raw water of Al-Harthah drinking water station at Basrah city during July 2010. temperature was at 29ºC, pH value on alkaline side 8.3 , electrical conductivity was 1592 μmos /cm and dissolved oxygen at 6.7 mg /L , generally results showed close similarity to the Iraqi waters characteristics. At the biological side, Four species of cyanobacteria were identified in this study : Anabaena affinis, Microcystis aeruginosa , Nostoc linkia, and oscillatoria tenuis are classified as a toxic cyanobacteria in the world, two of them , M. aeruginosa and O. tenuis , were isolated in laboratory as axenic cultures and detected for producing the toxins by extracted by gel filtration and then detected by TLC technique that showed these species can producing two types of hepatotoxins called Microcystins: MC-LR and MC-YR. In addition, this paper confirm a highly efficiency of activated carbon to remove of microcystins from the aqueous extracted of present isolates by two methods, direct filtration through activated carbon and store with it for one day. | ||
