Evaluation Of Jatropha Oil For The Production Of Polysydroxyalkanoates (PHAs) By Cupriavidus Necator H16

Jatropha oil, a non-edible vegetable oil, could serve as an alternative substrate to food grade oils for polyhydroxyalkanoates (PHAs) production. Jatropha oil contains oleic acid (42%), linoleic acid (35%) and palmitic acid (17%) as the major fatty acid constituents. Cupriavidus necator H16 accumula...
