1. Fengycin sythesis genes: fengycin is an antibiotic produced by Bacillus subtilus. It was synthesis by polypeptide synthesis.
2. Isolation and application of thermophilic bacteria from hot spring of Taiwan. We found several novel species including Pseudoxanthomonas taiwanensis, Meiothermus taiwanensis, Rubrobacter taiwanensis .
3. Biofilm formation and quorum sensing of thermphilic bacteria. While we are working with thermophilic bacteria, we found some of them with the ability to form biofilm. Different strains isolated from the same spot will be found in the same biofilm architecture. It is suggested that they will communicate with each other by quorum-sensing molecules.
4. Gene regulation of IAA metabolism in Acinetobacter baumannii
5. Gene regulation of tert-butyl hydroperoixied resistance genes in Acinetobacter baumannii
6. Gene regulation of Ethanol metabolism.
7. Two-component system for gene regulation.
