Twigs (young and old) from Nothapodytes foetida growing in the Jammu and Mahabaleshwar regions in India were used for the isolation of 52 strains of endophytic fungi and were tested for their ability to produce the anticancer alkaloid camptothecin. One of the isolates from the inner bark tissue of the N. foetida plant growing in the Jammu region of J&K state, India, was found to produce detectable quantities of camptothecin and its derivatives when grown in a semi-synthetic liquid medium. Camptothecin was identified by physicochemical analysis and further confirmed by spectroscopic studies. No camptothecin was detected in zero time cultures or in uninoculated culture broth. The maximum yield of camptothecin was 0.575 ± 0.031 mg/100 g of dry cell mass in 96 h in shake flasks, whereas 4.96 ± 0.73 mg/100 g of dry mass was recorded in 48 h in a bioreactor.Key words: endophytes, camptothecin, anticancer drug, Nothapodytes foetida, Entrophospora infrequens, bioreactor, scale-up.
