Labelling of precipitation by stable isotopes (18O, 2H) over the Jos Plateau and the surrounding plains (north-central Nigeria)

Application of stable isotope labelling

Application of stable isotope labelling methodology to the biosynthesis of the mycotoxin, terretonin, by aspergillus terreus: incorporation of 13C-labelled acetates and methionine, 2H- and 13C, 18O-labelled ethyl 3,5-dimethylorsellinate and oxygen-18 gas

Incorporation of 13C-labelled acetates and methionine, 14C and ZH-labelled ethyl 3,5-dimethylorsellinate into terretonin (5) by cultures of Aspergillus terreus indicated that its biosynthesis proceeds via a mixed polyketide-terpenoid (meroterpenoid) pathway. Incorporation of 1803 gas and ethyl 3,5-d
