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. Their… Expand
Sorption and desorption of sulfadiazine in soil and soil-manure systems.
Sulfadiazine is a widely used veterinary medicine that has high potential to enter the environment, especially the soil compartment by the application of manure on agricultural land and grass land or… Expand

A fungal endophytic isolate, camptothecin, has been isolated from the inner bark of the plant Nothapodytes foetidafrom the Western coast of India. The fungus, which belongs to the family… Expand
Fusarium species and mycotoxin profiles on commercial maize hybrids in Germany
High year-to-year variability in the incidence of Fusarium spp. and mycotoxin contamination was observed in a two-year survey investigating the impact of maize ear rot in 84 field samples from… Expand

Leaf-cutting ants cultivate the fungus Leucoagaricus gongylophorus, which serves as a major food source. This symbiosis is threatened by microbial pathogens that can severely infect L. gongylophorus.… Expand
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 do… Expand
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 to… Expand
Photolysis of 14C-sulfadiazine in water and manure.
Photolysis of 14C-sulfadiazine in aqueous solution under simulated sunlight followed first-order kinetics. The impact of H2O2, humic acid, fulvic acid and acetone to enhance the photodegradation of… Expand
