Aspergillus을 이용하요 생리적 제성질을 조사하였던 바 다음과 같은 결론을 얻었다. 1) 각 균주들은 각각 그들의 특성을 가지고 있었으며 이로서 균동정의 가능성을 나타내었다. 2)Amilase측정결과에서 보면 비교적 역가가 높은 균주들이 관찰되었으며, 이는 일주문의 경과에 따라 역가가 증가하였으나 protease의 역가는 우수한 균주를 발견키가 어려웠다. 3)Iodine의 착색대와 비착색대의 비율에 의한 역가의 정성적인 측정이 가능하였다.

Relationship of soil properties and seasonal variation on microbilogical population to-continuous culture and first-time culture of ginseng was investigated by bimonthly from May 1976 to January 1977. pH and P contents of 2 years continuous culture of soil were higher than other culture plot of soil, and contraty to the above, 2 years first-time culture of ginseng soil was conplot of soil, and contraty to the above, 2 years first-time culture of ginseng soil was contained more potassium contents than other culture plot of soil. In microbiological fluctuation with seasonr in various soil conditions, the population, trends of Fusarium spp., Erwiniaspp., and flourescent Psedudomonas spp. were increased in May and July in general, but decreased in the other month. It was observed that in all type of soil, Fusarium spp. was distributed in abundance in and on rihizosphere, and decreased the propagules numbers as soil depth increase. The numbers of Erwinia spp. and fluorescent Pseudo-monas spp. were distributed greater in numbers on the surface zone of soil depth decreasing the numbers along the soil layer increase, and also in 2years continuous culture of soil especially, a great numbers of Erwinia spp. and fluorescent Pseudomonas were evenly distributed in surface zone and rhizosphere. Ginseng disease with a high incidence of bacterial disease in continuous culture of 2 and 4 years was seemed to be associated with soil bacteria that was high in numbers of Erwinia spp. and fluorescent Pseudomonas spp. in May and July.
