Abstract
A process for producing polyhydroxyalkanoates (PHA) is provided. The process comprises: providing a waste stream comprising lignocellulosic materials; adding an calcium-containing mineral to the waste stream; heat-treating the waste stream in the presence of the calcium-containing mineral, to obtain a treated waste stream; fermenting at least one strain of PHA-producing microorganism in a culture medium comprising the treated waste stream as a carbon source, to produce the PHA; and extracting the PHA from the PHA-producing microorganism.
