Volatile Compounds Produced in Sterile Fish Muscle ( Sebastes melanops ) by Pseudomonas putrefaciens, Pseudomonas fluorescens , and an Achromobacter Species

Volatile compounds produced byPseudomonas putrefaciens, P. fluorescens , and anAchromobacter species in sterile fish muscle (Sebastes melanops ) were identified by combined gas-liquid chromatography and mass spectrometry. Compounds produced byP. putrefaciens included methyl mercaptan, dimethyl disulfide, dimethyl trisulfide, 3-methyl-1-butanol, and trimethylamine. With the exception of dimethyl trisulfide, the same compounds were produced by anAchromobacter species. Methyl mercaptan and dimethyl disulfide were the major sulfur-containing compounds produced byP. fluorescens .
