초록

영어
In this study, we aimed to isolate agarase using chromatographic method from the fermentation broth of bacteria, GNUM-0812-2, which was isolated and selected from several sites along the coastal regions of Tongyeong and Jindong located at South Korea. After 4-day culture of this strain, crude enzyme extracts were obtained from supernatant by ammonium sulfate precipitation followed by membrane dialysis. A anion exchange resins, DEAE sepharoseTM(Amersham Biosciences, Sweden) were packed into column and then adsorption and elution conditions of enzyme were optimized in batch-type experiments. Adsorptions of enzyme were investigated at different equilibrium pH and pH 7.2 was found to be suitable. The ratios between resin and amount of loaded enzyme were also optimized. The elution performances of bind
enzyme were compared at different concentrations of NaCl in elution buffer. Enzyme activity was monitored quickly by high throughput screening system developed by our group. Protein concentration was measured using commercial Assay kit (PIERCE). SDS-PAGE and Zymographies [1] were used for identifying the purified agarase
