Abstract
The growth inhibitions of each strain on tryptic soy broth containing various concentration of 75% ethanol extract of Sinomenium acutum(Thunb.) Rehd. et wils and Glycyrrhiza glabra L. var. glandulifera Regel were compared which were exhibited comparatively strong growth inhibition on Listeria monocytogenes ATCC 19111, 19112, 19113, 19114 and 15313 at previous screening test by disk method. The Sinomenium acutum(Thunb.) Rehd. et wils extract showed partly effect by its concentration in broth to L. monocytogenes ATCC 19111 and 19114. The Glycyrrhiza glabra L. var. glandulifera Regel extract inhibited the growth of all test strains and even 100 ppm of the extract in the broth inhibited the growth of all test strains of L. monocytogenes for 12 to 48 hours. The extract stopped the growth totally of all strains in 500 ppm addition level. L. monocytogenes ATCC 19113 was more sensitive than other strains.
Disk method에 의한 예비 실험 결과 Listeria monocytogenes ATCC 19111, 19112, 19113, 19114 및 15313에 대하여 성장억제 효과가 있었던 방기 및 감초의 75% ethanol 추출물을 농도별로 tryptic soy broth에 첨가하고 각 균주를 증식, 그 저해 정도를 비교하였다. 방기는 실험대상 균주 중 L. monocytogenes ATCC 19111 및 19114에 부분적으로 효과가 있었고 첨가 농도에 따라 그 증식 저해 정도는 비례하였다. 감초 추출물은 실험 대상 5균주 모두에 강한 항균성을 보였으며 대부분 100ppm 첨가에서도
