Abstract
A method for producing polyhydroxyalkanoate (PHA) comprises the steps of culturing in a culture medium comprising pyrolysis wax obtained from the pyrolysis of polyethylene and optionally a surfactant one or more bacterial strains which are capable of accumulating PHA from pyrolysis wax, and recovering the PHA from the culture medium. Typically, the bacterial strains are selected from the group consisting of: A. calcoaceticus BD413; A. calcoaceticus RR8; B. sepacia RR10; P. aeruginosa 3924; P. aeruginosa GL-1; P. aeruginosa PAO1; P. aeruginosa RR1; and P. olevorans.
