Bioprocessing aspects of fuels and chemicals from biomass


This review deals with a recent development of biofuels and chemicals from biomass. Some of the grainbased biofuels and chemicals have already been in commercial operation, including fuel ethanol, biodiesel, 1.3-propanediol, polylactic acid (PLA) and polyhydroxy butyric acid/alkanoates (PHB/PHA). The next generation bioproducts will be based on lignocellulosics due to their abundance and to stabilize rising food prices. However, the technologies of handling biomass are yet in their infancy and suffer from low yield, low product titer, and low productivity. This review focuses on bioprocessing technologies for biofuels production: organic raw biomaterials available in Korea; volatile fatty acids platform, multi-stage continuous high cell density culture (MSC-HCDC), enrichment of fermentation broth by forward osmosis; various purification methods of pervaporation of ethanol, solvent extraction on succinic, lactic acids and reactive separation methods.

Won Hi Hong is a professor in the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST). He received his BS from Seoul National University, Dipl.-Ing and Dr.-Ing at Technical University Berlin, Germany. From 1980 to 1984, he worked as a researcher at TU Berlin and then as a senior researcher at KAIST in 1984 before joining as an assistant professor at KAIST. His current professional fields of interest include extraction/purification of organic acid, CO2 absorption, direct methanol fuel cell (DMFC), advanced nanomaterial and microfludic system for biosensor, and synthesis and application of nanostructured carbon nitride. As many as about 160 journal papers, h-index-22(SCI), 32(Google) and 16 patents of his research achievements have been published so far.
