Abstract
Pseudomonas oleovorans was grown on 6-methylnonanoic acid (6-MNA), 7-methylnonanoic acid (7-MNA), 8-methylnonanoic acid (8-MNA), 9-methyldecanoic acid (9-MDA), 7-methyldecanoic acid (7-MDA), and 2,6-dimethylhept-5-enoic acid (2,6-DMHA). Poly(β-hydroxyalkanoate)s (PHAs) were obtained when this bacterium was grown on pure 9-MDA, 8-MNA, 7-MNA, and 6-MNA, but not on 7-MDA and 2,6-DMHA. The mixtures of n-nonanoic acid (NA) and either 7-MDA or 2,6-DMHA gave almost pure nonanoic acid homopolymers. For the other branched substrates, 1 H and 13 C NMR studies showed that the polymers obtained contained the type of methyl branching expected from the starting alkanoic acid
