Economic analysis of polyhydroxybutyrate production by Cupriavidus necator using different routes for product recovery

The aim of this study was to conduct an economic assessment of the entire polyhydroxybutyrate (PHB) production process by Cupriavidus necator, using citric molasses as carbon source and employing propylene carbonate as solvent coupled with different extraction pretreatment methods. Four extraction alternatives were assayed. The alternatives that uses high pressure and heat to pretreat the biomass showed equally lower production costs (US$ 4.28...
