Identification of the S-containing volatile from M. hyalina
To identify the main S-containing volatile produced by M. hyalina , the compound needed to be enriched for further analysis. For that, M. hyalina was cultured in liquid PDA media for two weeks at 23 °C in the dark without shaking. The fungus mats produced on the surface of the media were collected (total FW ≈ 180 g), rinsed twice with tap water and cut into pieces. The fungus material was subjected to hydro-destillation to obtain the essential oil which was further analyzed by NMR and GC-MS.
