Biodiesel 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 کاملMicrobial Conversion of Waste Glycerol from Biodiesel Production into Value-Added Products
Biodiesel has gained a significant amount of attention over the past decade as an environmentally friendly fuel that is capable of being utilized by a conventional diesel engine. However, the biodiesel production process generates glycerol-containing waste streams which have become a disposal issue for biodiesel plants and generated a surplus of glycerol. A value-added opportunity is needed in ...
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 کاملHigh production of 2,3-butanediol from biodiesel-derived crude glycerol by metabolically engineered Klebsiella oxytoca M1
BACKGROUND 2,3-Butanediol (2,3-BDO) is a promising bio-based chemical because of its wide industrial applications. Previous studies on microbial production of 2,3-BDO has focused on sugar fermentation. Alternatively, biodiesel-derived crude glycerol can be used as a cheap resource for 2,3-BDO production; however, a considerable formation of 1,3-propanediol (1,3-PDO) and low concentration, produ...
متن کاملGlycerol production by microbial fermentation: a review.
Microbial production of glycerol has been known for 150 years, and glycerol was produced commercially during World War I. Glycerol production by microbial synthesis subsequently declined since it was unable to compete with chemical synthesis from petrochemical feedstocks due to the low glycerol yields and the difficulty with extraction and purification of glycerol from broth. As the cost of pro...
