Burkholderia sp. Yu-4 was cultured to produce PHAs by using glucose (as the first carbon source) and organic salts (sodium propionate or sodium valerate as the second carbon source) in a nitrogen-limited medium. A one-time-one-factor method was used to explore the effects of types of nitrogen and carbon sources, organic salts and their concentrations on PHBV biosynthesis and to search for optimal conditions for batch fermentation. From the results of one-time-one-factor experiments using various carbon sources (based on the same amount of carbon in glucose) and ammonium sulfate as the nitrogen source in a flask culture, glucose was the best carbon source, and yields of biomass and PHB reached 4.53 and 1.96 g/L, respectively. When Burkholderia sp. Yu-4 was cultured in various nitrogen sources (based on the same amount of nitrogen in ammonium sulfate) and glucose (as the carbon source), ammonium sulfate was the best nitrogen source to yield the highest biomass (4.90 g/L) and PHB (1.63 g/L). If sodium valerate was added as the second carbon source, the best timing was at 6 h to add this salt. For sodium propionate, the biomass and PHBV production reached 6.02 and 2.38 g/L (HB 2.33 g/L and HV 0.05 g/L), respectively. For sodium valerate, the biomass and PHBV production reached 3.95 and 1.76 g/L (HB 1.52 g/L and HV 0.24 g/L), respectively. When the concentration of organic salt was considered as a factor, the results show that the most appropriate concentration for sodium propionate was 1 g/L, and the biomass and PHBV reached 4.95 and 2.09 g/L (HB 1.95 g/L and HV 0.14 g/L), respectively. For sodium valerate, the most appropriate concentration was 4 g/L, the biomass, and PHBV were 4.93 and 1.98 g/L (HB 1.57 g/L and HV 0.41 g/L), respectively. If no organic salt was added, the optimal PHB production reached 3.95 g/L, and the biomass was 6.47 g/L in a batch fermenter.

In this study, sodium valerate was added in a nitrogen-limited medium as the second carbon source (glucose as the primary carbon source) to cultivate strain Yu-3 to produce PHBV (poly-hydroxybutyrate-co-valerate). A preliminary study was performed, one-factor-at-a-time, to investigate the effects of cultivating conditions on the biosynthesis of PHBV. The cultivating conditions included the glucose concentration, timing of adding sodium valerate, and sodium valerate concentration. The results obtained in the method of one-factor-at-a-time were then used in a central composite design to search for an overall optimal condition to produce PHBV. First of all, strain Yu-3 was cultivated with various glucose concentrations(10, 20, 30, 40, 50 g/L). The glucose concentration, 20 g/L, is the best case in which the biomass, PHB and PHV reached 4.29, 0.84 and 0.25 g/L, respectively, and PHB/biomass being 19.58%. When strain Yu-3 was cultivated using sodium valerate as the second carbon source, the best timing of adding sodium valerate was 12 h. The biomass, PHB and PHV reached 6.25, 1.56 and 0.47 g/L, respectively, and the ratio of PHB/biomass was 24.96%. When strain DYU Yu-3 was cultivated with various sodium valerate concentrations (1, 2, 3, 4, 5 g/L), the sodium valerate concentrations, 5 g/L, is the best case in which the biomass, PHB and PHV reached 4.84, 0.29 and 0.76 g/L, respectively, and PHB/biomass being 5.99%. The best result obtained from the one-factor-at-a-time experiments was further examined and used as the center point in a central composite design. Finally, the optimal condition was composed of 19.78 g/L glucose, 7.97 g/L sodium valerate, and the timing of adding sodium valerate at 16.5 h. To validate the above result from the central composite design, an experiment was repeated at the optimal condition. The biomass, PHB and PHV reached 5.22, 0.35 and 0.93 g/L, respectively, and the ratio of PHV/biomass was 17.81% which was in the range of the anticipated interval (18.30±2.93%). The optimal condition was further tested in a batch fermenter. The biomass, PHB and PHV reached 7.31, 0.43 and 2.36 g/L, respectively, and the ratio of PHV/biomass was 32.28%. These results surpass the ones obtained in the flask culture.
