Summary of actinobacterial olefin producing genera. A simplified tree of the Gram-positive order Micrococcales within the Actinobacteria phylum is shown on the left. Genera are marked in red if they include species and strains from which olefins have been successfully extracted. Genera with only a positive in silico screening result for oleABCD are marked in blue. On the right, a representative average of the olefin profiles (chain lengths and isomers) of the olefin-synthesizing genera is shown, as well as the produced amounts. Abbreviations: isoiso, iso-branched at both ends; isoai, iso-branched at one end and anteiso-branched at the other end; aiai, anteiso-branched at both ends; isosc, iso-branched at one end and no branching at the other end; aisc, anteiso-branched at one end and no branching at the other end; scsc, no branching at both ends [15]
