Chemical ecology of endophytic fungi: origins of secondary metabolites.
Endophytes constitute a remarkably multifarious group of microorganisms ubiquitous in plants and maintain an imperceptible association with their hosts for at least a part of their life cycle. TheirExpand

An endophytic fungus from Camptotheca acuminata that produces camptothecin and analogues.
The pentacyclic quinoline alkaloid camptothecin (1) is a potent antineoplastic agent. Two of its analogues, 9-methoxycamptothecin (2) and 10-hydroxycamptothecin (3), exhibit similar potency but doExpand

Fate of sulfadiazine administered to pigs and its quantitative effect on the dynamics of bacterial resistance genes in manure and manured soil
Abstract The veterinary antibiotic sulfadiazine (SDZ), labelled by 14 C, was administered to pigs to follow the fate of the drug and its metabolites in manure and manure-amended soil, and toExpand
