Polyhydroxyalkanoates production by engineered Cupriavidus necator from waste material containing lactose.
Cupriavidus necator DSM 545 is a well-known polyhydroxyalkanoates (PHAs) producer, but unable to grow on lactose. The aim of this study was to construct a recombinant strain of C. necator that can use lactose-containing waste material such as cheese whey, to produce PHAs. One of the intracellular PHA depolymerases (phaZ1) of C. necator was chosen to insert the lacZ, lacI and lacO genes of Esche...
متن کاملPoly(hydroxyalkanoate) Production by Cupriavidus necator from Fatty Waste Can Be Enhanced by phaZ1 Inactivation
Although PHAs are regarded as an effective substitute for conventional plastics for a number of medical and agricultural applications1 and food packaging2, their full-scale manufacturing is hampered by high production costs3. Factors affecting the cost of PHAs include raw materials availability, suitable process design, and downstream processing4,5. Since almost 50 % of the total production cos...
متن کاملFactors Affecting Poly(3-hydroxybutyrate) Production from Oil Palm Frond Juice by Cupriavidus necator (CCUG52238T)
Factors influencing poly(3-hydroxybutyrate) P(3HB) production by Cupriavidus necator CCUG52238(T) utilizing oil palm frond (OPF) juice were clarified in this study. Effects of initial medium pH, agitation speed, and ammonium sulfate (NH(4))(2)SO(4) concentration on the production of P(3HB) were investigated in shake flasks experiments using OPF juice as the sole carbon source. The highest P(3HB...
متن کاملBiodiesel Production From Rapeseed Oil With Waste Frying Oils
Biodiesel or fatty acids alkyl esters (FAAE) of long chain are an alternative fuel produced by a transesterification process. The potential production of biodiesel from rapeseed oil in Chile is associated to the solution of economic, environmental and social problems. Experiences from other countries have demonstrated that biodiesel prices are higher than diesel, due to the high costs of the ra...
متن کاملPolyhydroxyalkanoates production from waste biomass
Polyhydroxyalkanoates (PHAs) is a group of biopolymers that are extensively researched for such purpose due to the biocompatibility with mammal tissue and similar properties with conventional plastic. However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. Thus, cheap and sustainable feedstocks are pref...
