Optimization of the nitrogen source in the polyhydroxyalkanoate (PHA) production medium. (a) Cell growth and PHA production were compared in the presence of various nitrogen sources. Effect of the concentration of the yeast extract on (b) PHA production and (c) PHA mole fraction were obtained. Statistical analysis was carried out by applying ANOVA with the level of significance at 5%. 3HB, 3-hydroxybutyrate; 3HV, 3-hydroxyvalerate; DCW, dry cell weight; HHx, 3-hydroxyhexanoate; OD, optical density.
