Abstract

Three kinds of microoganisms were isolated and identified from the ginseng and ginseng products to research the properties of the molds which spoil the ginseng and ginseng products. The results obtained were as follows: (1) The predominant strains on ginseng products were Aspergillus sp., Penicillium sp.-A and Penicillium sp.-B. These predominant fungi deteriorated ginseng products exclusively, (2) Aspergillus sp. showed the greatest mycelial growth at $40^{\circ}C$ and its optimum pH was 5, meanwhile Pencillium sp. showed the greatest mycelial growth at $30^{\circ}C$ and its optimum pH was 3. (3) The growth of the isolated strains was stimulated with the increase in the concentration of saponin at the lower concentration, meanwhile it was inhibited at 1.0% concentration of saponin.
