Biodegradation of microcystin-LR by a genetically engineered bacterium

摘要：

Introduction Toxic blooms of cyanobacteria occur worldwide in the eutrophic lakes, ponds and reservoirs. Microcystins (MCs) are the most commonly detected cyanobacterial toxins. Now over 70 structural analogues of MCs have been identified, in which MC-LR is a most toxic type detected frequently in the water bodies occurring toxic blooms of cyanobacteria. Generally, MC-LR is mainly produced by cyanobacterial cells when the temperature is below 25℃ 1.2. MCs are toxic to mammals, fish, plants and invertebrates 3-6. Recent concerns about chronic exposure of humans to MCs in drinking water have led to a recommendation by the World Health Organization, advising that MC-LR concentration in drinking water should not exceed 1.0 μg/L 7, adopted by China in 2006. MCs are known to be chemically stable compounds 8.
