Microbial production of succinic acid using crude and purified glycerol from a Crotalaria juncea based biorefinery
Microbial conversion of crude and purified glycerol obtained in the process of biorefining Crotalaria juncea is carried out to produce succinic acid using Escherichia coli. Batch tests are performed for nine different substrate concentrations of commercial, purified and crude glycerol, in order to observe cell growth and substrate utilization rate. Inhibitory (Halden-Andrew, Aiba-Edward, Tessie...
متن کاملCharacterization of Crude Glycerol from Biodiesel Production from Multiple Feedstocks
Glycerol is the principal by-product of biodiesel production. For each gallon of biodiesel produced, approximately 0.3 kg of crude glycerol accompanies. Such crude glycerol possesses very low value because of the impurities contained. As the demand and production of biodiesel grow exponentially, the utilization of the glycerol becomes an urgent topic. The make-up of crude glycerol varies depend...
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 کاملAnaerobic treatment of crude glycerol from biodiesel production.
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas p...
متن کاملBiotechnological production of 1,3-propanediol from crude glycerol
1,3-Propanediol (1,3-PD) is one of the important products used in chemical industry, in particular for polyesters production (e.g. polyethers and polyurethanes). Using crude glycerol for producing 1,3-PD is a good solution from the economical as well as ecological point of view. Glycerol produced by cleavage of natural fats can be microbially converted to 1.3-propanediol by, among others, Citro...
