| Research Abstract |
Enzymes acting on dibenzothiophene (DBT) and fucoidan were investigated ; DBT was contained in petroleum and fucoidan in algae. Since combustion of petroleum released substances for acid rain, "desulfurization" is a necessary step before combustion. DBT degrading enzymes was applicable to biodesulfurization, and the enzyme was improved by genetic engineering method in this study. Fucoidan is a high-molecular-weight compound with physiological activities such as anticancer one, and decreasing the molecular weight would lead to finding of new activities. Novel fucoidan-degrading microorganisms were isolated, and enzyme activities were detected in this study.
