Fermentative Polyhydroxybutyrate Production from a Novel Feedstock Derived from Bakery Waste

Figure 1

Fermentative PHB production. Profile of glucose (closed circle), fructose (open square), free amino nitrogen (FAN, open triangle), and biomass (closed triangle) concentrations as well as weight specific PHB content (open circle) during fermentation of Halomonas boliviensis on bakery waste hydrolysate ((a) and (b)). Fermentations were initially performed as batch cultures and later changed to fed-batch cultures. Start of feeding is indicated by an arrow.
