Biotransformation of Artemisinin by using a Novel Soil Isolated Microorganism

Artemisinin is a potential antimalarial drug effective against the multidrug resistant forms of Malarial Parasites. The current production of artemisinin is insufficient to meet the global demand. In the present study microbial biotransformation of arteannuin B, a biogenetic precursor of artemisinin to the later has been investigated. Screening studies carried out on several soil borne microorganisms have yielded one novel species with the bioconversion ability. Crude cell free extract of 72h old culture of the isolate had shown the bioconversion activity. On incubation with the substrate arteannuin B, crude cell free extract of the isolate had shown a bioconversion of 18.54% to artemisinin on molar basis with a specific activity of 0.18 units/mg.
