Abstract
Optimum conditions for immobilization of thermolysin, a metalloendopeptidase catalyzing synthesis of aspartame precursors, were investigated with using Amberlie XAD-7 as carrier and glutaraldehyde as cross-linking agent. Adsorption of thermolysin onto the carrier was rapid at the initial stage and 96% of the enzyme was adsorbed after 24 hours at
아스파탐 전구체의 보다 효율적인 효소적 합성 방법을 개발하기 위하여 thermolysin의 고정화 방법을 확립하고자 고정화 담체로서 다공성 수지인 Amberlite XAD-7을, 가교화제로서 glutaraldehyde를 사용하여 최적 고정화 조건을 조사하고자 하였다. Thermolysin이 Amberlite XAD-7에 흡착되는 속도는 초기에 빠른 것으로 나타났으며,
