Abstract
This experiment was carried out to investigate the bacteriolytic action of the egg white lysozyme isolated from Korean native Ogol fowl and to obtain the data for utilization of the enzyme as a food preservative. Staphyococcus aureus phage type 29 and Bacillus subtilis ATCC 6633 among the microorganisms tested were lyzed by the treatment with 0.05% lysozyme, but Staphylococcus aureus phage type 57 in addition to E. coli etc. was found to be a lysozyme- insensitive species. The lysis of S. aureus phage type 29 was maximized when incubated in nutrient broth (pH 7.0) at
오골계 난백 lysozyme의 용균특성을 조사하고, 이를 식품보존료로 이용하기 위한 자료를 얻고자 오골계 난백으로부터 추출 분리한 lysozyme의 각종 미생물에 대한 용균성을 조사하였다. 그 결과, 공시균중 Gram 양성균인 Staphylococcus aureus phage type 29와 Bacillus subtilis ATCC 6633에 대하여는 용균성이 인정되었으나, Gram 음성균인 E. coli를 비롯한 여타의 균종과 Staphylococcus aureus phage type 57은 lysozyme에 대한 용균 감수성이 인정되지 않았다. 분리된 lysozyme은 S. aureus phage type 29를 공시균주로 하여 이를 육즙배지에 접종하고,
