To investigate the methyl source, (CD3)-C-13-labelled L-methionine was added to the growth medium. After one month sodium borohydride reduction of media samples produced dimethylstibine and trimethylstibine. The methylstibines were separated on a packed GC column and obtained as gaseous fractions. Analysis of the methylstibines, in the gaseous fractions, by CGC-MS (lion-trap) established (CD3)-C-13 incorporation in both the trimethyl-and dimethyl-antimony compounds.
