Abstract: There has been a considerable interest in using low cost carbon substrates for the production of Poly(3-hydroxybutyrate) (PHB). We have shown that saccharified waste potato starch can be used as a viable alternative carbon source in high cell density PHB production. Using Ralstonia eutropha NCIMB 11599 with phosphate limitation, 179 g/l biomass, 94 g/l PHB, Y(biomass/starch) = 0.46 g/g, Y(PHB/starch) = 0.22 g/g, and PHB productivity = 1.47 g/(l*h) were achieved. Residual maltose accumulated in the fed-batch reactor but caused no noticeable inhibition. Performance with saccharified starch was virtually identical to that with glucose.
