오골계 난백 lysozyme의 용균활성은 Bacillus sp. TA-11를 50℃에서 18시간 정치배양한 대수기 후기의 세포에 대하여 가장 높았고, lysozyme의 농도는 0.25%가 최적이었다. 또한 lysozyme의 최적반은 pH와 온도는 각각 4.5와 35℃였다. 일반 난백 lysozyme의 용균활성은 시험균주를 24시간 배양한 정지기의 세포에 대하여 가장 높았고 lysozyme의 최적 농도는 0.5%였으며 반응 최적 pH와 온도는 각각 5.5과 40℃이었다.
Lytic activities of the egg white lysozyme from Korea-native Ogol fowl and a fowl against the alkalophilic and thermophilic Bacillus sp. TA-11 were investigated and compared. Lytic actinity of the Ogol fowl lysozyme for Bacillus sp. TA-11 was the highest for the cell of post-logatithm phase and optimum concentration of the lysozyme was 0.25%. Optimum reaction pH and temperature were 4.5 and 35℃, respectively. Lytic activity of egg white lysozyme from fowl for Bacillus sp. TA-11 was the highest for the cell of stationary phase and optimum concentraion of the lysozyme was 0.5%. Optimum reaction pH and temperature were 5.5 and 40℃, respectively.
