3-Hydroxypropionaldehyde production from crude glycerol by Lactobacillus diolivorans with enhanced glycerol uptake
Background In their quest for sustainable development and effective management of greenhouse gas emissions, our societies pursue a shift away from fossil-based resources towards renewable resources. With 95% of our current transportation energy being petroleum based, the application of alternative, carbon-neutral products-among them biodiesel-is inevitable. In order to enhance the cost structur...
متن کاملMicrobial Production of 3-Hydroxypropionaldehyde from Glycerol Bioconversion
3-Hydroxypropionaldehyde (3-HPA) is of high industrial interest as a new platform intermediate from bioconversion of renewable materials because it can be converted into a number of large scale commodity chemicals. In this work we studied the production of 3-HPA from bioconversion of glycerol in a two-stage process. In the first stage active biomass is produced. The active biomass is then used ...
متن کاملGlycerol metabolism in Lactobacillus collinoides: production of 3-hydroxypropionaldehyde, a precursor of acrolein.
Lactobacillus collinoides is a lactic acid bacterium commonly found in fermenting apple juice. Although this bacterium is not particularly involved in malolactic conversion, the presence of L. collinoides in cider may have serious consequences on the product. L. collinoides is indeed considered to be responsible for the transformation of glycerol to 3-hydroxypropionaldehyde (3-HPA), a precursor...
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 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...
