Pietro Buzzini et al.
FEMS yeast research, 5(4-5), 379-385 (2005-02-05)
Thirty-seven basidiomycetous yeasts belonging to 30 species of seven genera were grown on media containing l-cysteine or l-methionine as sole nitrogen sources with the objective of evaluating volatile organic sulfur compound (VOSC) production. The headspace of yeast cultures was analyzed
