The possibility to convert mono-aromatic compounds (BTEX,
styrene) into PHA has been previously reported using P. putida
strains (Ward et al., 2005; Nikodinovic et al., 2008). Berezina
et al. (2015) reported that benzoic acid was found to be a crucial
compound for the bioremediation by Cupriavidus necator, and this
strain transforms benzoic acid to the PHB showed that this bioremediation
process is more suitable for the purification of waste
streams. Koller and Braunegg (2015) reported PHB and poly(3-hy
droxybutyrate-co-3-hydroxyvalerate) (PHBV) production by C.
necator strain DSM 545 using animal-based crude glycerol phase
(CGP) and the saturated biodiesel share (SFAE).
