EXCRETION OF S- AND O-METHYL ESTERS AND OTHER VOLATILE COMPOUNDS BY OCHROMONAS DANICA

Article abstract of DOI:10.1016/0031-9422(82)85174-1

The formation of volatile excretion was studied in axenic cultures of Ochromonas danica.Under microaerobic conditions in the light, an accumulation of O- and S-methyl esters, alcohols, dimethyldisulphide was observed in the medium.Most of the compounds are structurally derived from the amino acids methionine, valine , leucine and isoleucine.The excreted volatile compounds, particularly the methyl thioesters, were rapidly metabolized in the dark.Key Word Index - Ochromonas danica; metabolism; volatile excretion products; O-esters; S-esters; microaerobiosis.
