Bioremediation of Cyanotoxins

Cyanobacteria are a diverse group of mainly aquatic microorganisms which occur global y. Eutrophication (nutrient enrichment) of water bodies, often as a result of human activities, results in prolific grow of cyanobacteria I hat develop into a thick scum or bloom. Many of these blooms are toxic due to the production of hepato-toxins (microcystins and cylindrospermopsin) and/or neurotoxins (saxitoxins and anatoxins) posing a serious health hazard to humans and animals. The presence of these cyanotoxins is of particular concern in drinking water supplies where conventional water treatment often fails to eliminate them. Hence, there is significant interest in water treatment strategies that ensure the removal of cyanotoxins, with the exploitation of microbes being on such possible approach.
