Figure 3From: Feasibility study of an alkaline-based chemical treatment for the purification of polyhydroxybutyrate produced by a mixed enriched culture Fraction of degradation products, HB (solid round) and CA (empty diamond), over total initial PHB (equations 3 and 4 ). The experiment was performed with fresh biomass at 30°C for 1 hour in duplicate. Initial PHB content was 68%.Back to article page
