In order to exploit cheap carbon source for poly(3\u2010hydroxybutyrate) (PHB) production, alligator weed hydrolysates were prepared by acid and enzyme treatment and used for PHB production via\n                    <jats:italic>Cupriavidus necator<\/jats:italic>\n                    . The bacterium utilized alligator weed enzymatic hydrolysate and produced the PHB concentration of 3.8\u2009\u00b1\u20090.2\u2009g\/L at the conditions of pH\u20097.0, 27.5\u00b0C, 1.5\u2009g\/L of nitrogen source, and 25\u2009g\/L of carbon source, this exceeded the value of 2.1\u2009\u00b1\u20090.1\u2009g\/L from acid hydrolysate media at the same conditions. In order to obtain the optimum conditions of PHB production, response surface methodology was employed which improved PHB content. The optimum conditions for PHB production are as follows: carbon source, 34\u2009g\/L; nitrogen source, 2\u2009g\/L; pH, 7; temperature, 28\u00b0C. After 72\u2009hr of incubation, the bacterium produced 8.5\u2009g\/L of dry cell weight and 4.8\u2009g\/L of PHB. The PHB was subjected to Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and Molecular weight analysis and found the melting temperature, number average molecular mass, and polydispersity were 168.20\u00b0C, 185\u2009kDa, and 2.1, respectively.\n
