Identification of heptadecane produced by Anabaena 7120. a GC/MS chromatograph of the volatile metabolites from Anabaena 7120 cultures. A peak at the retention time of 6.31 min (black arrow) found in Anabaena matches the heptadecane standard (c). b, d Mass spectra of the 6.31 min peaks display the fragmentation pattern for the compound in Anabaena and the heptadecane standard, respectively. Five μg mL−1 tetracosane serves as an internal standard (IS, blue arrow)
