Polyhydroxyalkanoates (PHAs), bioprocessing using waste oil

Pseudomonas oleovorans NCIMB 6576 and Ralstonia eutropha 10442 were used for the production of Polyhydroxyalkanoates (PHA) from industrial waste cooking oils, bacteria cultured on tryptone soya broth (TSB) Tryptone agar (TSA). P. NCIMB6576 gave a better percentage PHB yield (8.2%) with PS oil as carbon source compared to 6.45% TS oil. However, very low (0.64%) was recorded when grown TSB without oils source. an appreciable 13.63% 14.80% samples respectively negligible variation in yields. The results obtained across all experiments one another. SEM images generated shows that there is slight difference surface morphologies respect well different experiment.
