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.
