Abstract
In present study, we are intrested in establishing a biological removal method by microorganism against the cyanobacterial hepatotoxin microcystion. A native microcystin-degrading bacterium was isolated from a shallow hypertrophic lake, and the biodegradation effect was detected by the LC-MS method. The 16S rDNA gene sequence analysis result indicated that the isolated strain T11 was belonged to the genus Arthrobacter sp., with a highest sequence similarity (98%) with Arthrobacter sp. C6 strain. LC-MS result showed that the Arthrobacter sp. T11 was able to effectively degrade, at a highest concentration of MC (MC-LR ~ 15 g·L-1; MC-RR ~ 20 g·L-1) in batch experiments using sterilized lake water conditions, with complete removal observed within 10 days.
