Background Polyhydroxybutyrate ( PHB ), an important member of the family of polyhydroxyalkanoates ( PHAs ), is a biodegradable thermoplastic synthesized by numerous microorganisms under different cultivation conditions . Results A simple dynamic model for producing PHB in a fed‐batch reactor is presented. The kinetic model accuracy is quantified by the specific error measures. The dynamic manipulation scheme with prescribed stepwise changes is used to improve PHB productivity. A multi‐objective optimization algorithm is used to determine the optimal feeding strategy . Conclusion Reduced kinetic models in a mixed culture cultivation process for PHB production are successfully verified. An optimization‐based feeding strategy with stepwise changes has been derived and successfully validated. © 2013 Society of Chemical Industry
