Biofuels Production from waste organic biomass (ethanol, butanol and biodiesel), Multi-Stage Continuous High Cell Density Culture (MSC-HCDC), High cell density cell culture with High age depth filter system
Volatile fatty acids (VFA: acetic acid, propionic and butyric acids) production using mixed culture technology. MSC-HCDC (multi-stage continuous high cell density culture) system for fuels and chemicals production from various biomass resources such as low cost organic wastes and marine biomass. The fuels refer to mixed alcohols of ethanol, propanol, and butanol; biodiesels, and chemicals are organic acids-derived. Catalytic production of hydrogen from VFAs,
Improving bioreactor productivity about 10 times the fed-batch with equivalent fed-batch titer. Enriching fermentation titer from 3% to 10~15% by membrane technology. Production of extracellular products such as ethanol, lactic acid monoclonal antibodies, and intracellular products such as PHB(polyhydroxy butyric acid), microbial lipids for biodiesel, and intracellular biomedical proteins.
