Although this technology has been
widely studied, it has never been previously proposed for the production
of syngas for use in fermentation processes. Moreover, no
studies have yet explored the possibility of applying microwaveinduced
pyrolysis to the biopolymer production process through
syngas fermentation. Once the syngas is fermented by bacteria, PHAcan be recovered by using a solvent extraction; e.g., using chloroform
and methanol [31] or combining surfactant addition to break
down the cell wall followed by solubilization of cell material with
sodium hypochlorite [23]. This stage should be followed by the separation
of the PHA-containing phase from the residual cell material
by sedimentation
