Polyhydroxyalkanoates (PHAs) are biocompatible and biodegradable
polyesters that exhibit physical–chemical, thermal and
mechanical properties very similar to those of conventional
plastics (Akaraonye et al., 2010). Low cost oil-containing wastes/
byproducts have been proposed as carbon sources for PHA production,
since they exhibit high product to substrate yield (up to
0.8 g g1) (Akaraonye et al., 2010; Obruca et al., 2010).
