| 제목 | Production of functional indigo derivative-incoporated polyhydroxybutyrate (IDPs) that can control biodegradability |
| 초록 | In this study, Indigo derivatives incorporating Poly(3-hydroxybutyrate)(IDPs) were produced in one-pot by engineered Escherichia coli. Several indigo derivatives were produced. Biological and physical properties, such as the anti- oxidant activity, biodegradability, melting temperature (Tm), glass transition temperature (Tg), average molecular weight, polydispersity index, hardness, and elasticity of the IDPs were analyzed. As a result of the measurement of Tm value, 5-OH IDP showed the highest Tm value at 181.1℃ among IDPs, and 4-NO2 IDP showed the lowest Tm value at 154.7℃. As a result of measuring the biodegradability of IDPs, 5-OH IDP was not the most biodegradable (2.6%), but 4-NO2 IDP showed the best biodegradability (18.9%). inally, the application of biodegradable PHB was expanded by coating IDPs on cellulose. |
