Proton NMR spectra of M9 medium, and fungal exudates. (A) M9 spectrum showing peaks corresponding to water and propionate. (B) Full spectrum of exudates of Lyophyllum sp. strain Karsten. (C) Full spectrum of exudates of T. asperellum 302. 3-(trimethylsilyl)-1-propanesulfonic acid sodium salt (DSS) was used as the internal standard (0.0 ppm). Corresponding peaks of compounds in exudates of Lyophyllum sp. strain Karsten (B) and T. asperellum 302 (C) are annotated with their names. Unknown peaks are denoted by (?).
