Toward glycerol biorefinery: metabolic engineering for the production of biofuels and chemicals from glycerol
As an inevitable by-product of the biofuel industry, glycerol is becoming an attractive feedstock for biorefinery due to its abundance, low price and high degree of reduction. Converting crude glycerol into value-added products is important to increase the economic viability of the biofuel industry. Metabolic engineering of industrial strains to improve its performance and to enlarge the produc...
متن کاملThermogravimetric kinetics of crude glycerol.
The pyrolysis of the crude glycerol from a biodiesel production plant was investigated by thermogravimetry coupled with Fourier transform infrared spectroscopy. The main gaseous products are discussed, and the thermogravimetric kinetics derived. There were four distinct phases in the pyrolysis process of the crude glycerol. The presence of water and methanol in the crude glycerol and responsibl...
متن کاملBiodiesel biorefinery: opportunities and challenges for microbial production of fuels and chemicals from glycerol waste
The considerable increase in biodiesel production worldwide in the last 5 years resulted in a stoichiometric increased coproduction of crude glycerol. As an excess of crude glycerol has been produced, its value on market was reduced and it is becoming a "waste-stream" instead of a valuable "coproduct". The development of biorefineries, i.e. production of chemicals and power integrated with conv...
متن کاملCRUDE GLYCEROL AS SUBSTRATE FOR SULFATE-REDUCING BACTERIA FROM A MATURE OIL FIELD AND ITS POTENTIAL IMPACT ON SOURING
Crude glycerol (CG) is an abundantly available and cheap by-product from biodiesel production. Value-added applications for CG are highly wanted by industry and several processes such as the use of CG for enhanced oil recovery have been proposed. The aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (SRB) indigenous to oil reservoirs using CG as substrate. Th...
متن کاملGlycerol Kinase: Substrate Specificityl
Glycerol kinase (8.C. 2.7.1.30, ATP: glycerol-3-phosphotransferase) catalyzes the phosphorylation of 28 nitrogen, sulfur, and alkyl-substituted analogues of glycerol. A survey of 66 analogues has defined qualitatively the structural characteristics nffissary for acceptability as a substrate by this enzyme. This survey was conducted using an assay based on 3lP NMR spectroscopy which detected pro...
