Figure 1. GC-MS chromatogram of the headspace of M. hyalina (black) and the growth medium alone (blue). Identified signals are not present in the headspace of the growth medium. The three strong signals in the chromatogram of the headspace of the growth medium could be identified by MS and RI as benzaldehyde (7.13 min) nonanal (9.44 min), and decanal (11.00 min).
