Analysis of the volatile metabolite geosmin produced by Microcoleus asticus sp. nov. using SPME GC-MS. Selected ion monitoring chromatogram in gas chromatography-mass spectrometry (GC/MS-SIM) of the ionic current of the selected geosmin ions (m/z = 111; 112; 125 and 126). (a) Geosmin detection in the Microcoleus asticus sp. nov. culture volatile extract; (b) Control analysis: 1- analytical geosmin standard (20 ng.ml−1), 2- no compound control, 3 - Z8 culture media.
