In situ bioremediation: Use of microbial metabolism and metabolic byproducts for degradation of toxic chemicals, metals and radionuclides, and mitigation of propagation of these contaminants.
Biological filtration: Improving the efficacy of biological water treatment systems for reducing humic acids and toxic heavy metals.
Recombinant DNA technique for biofilm formation mechanisms: The recombinant DNA fused with the reporter gene is used to investigate the biofilm formation mechanism at a molecular level. The mechanism study has been performed as a part of the new project to develop a novel material that prevents biofilm formation.
Metabolic pathway control: Nano-scale investigation of metabolic pathways in fermentation reactions in order to selectively increase the reaction yield of a target byproduct.
Biopolymer property control: Studying biopolymer gelation mechanisms and kinetics to determine more efficient methods for establishing a stable biologically active zone in in situ bioremediation and biological filtration, and to control biofilms in industrial and medical systems.
