Abstract

The change in microbial flora has been studied through dwelling house composting by the composter with double layer walls. The results are summarized as followes. 1. Mesophilic bacteria increased and decreased mildly, thermophilic bacteria showed a tendency to decrease except for spring, and the number of mesophilic bacteria and thermophilic bacteria had a tendency to increase and decrease simultaneously. 2. The number of mesophilic actinomycetes were increased at the early stage of compositing in winter, mildly decreased in spring and slightly decreased in summer, and the number of thermophilic actinomycetes were decreased at the early stage of composting. 3. The decrease in the number of mesophilic fungi was observed at the middle stage in summer, but the mild increase was observed in spring and winter. The number of thermophilic fungi was generally decreased. 4. Ammonia oxidizer and nitrite oxidizer were observed in this field composting much more than in the other composting experiments.

이중벽의 퇴비화 용기를 사용하여 가정 생활쓰레기의 현장에서의 미생물상의 변동을 조사하였다. 그 결과는 다음과 같다. 1. 중온성 세균은 다소 완만한 변화를 보였다. 고온성 세균은 봄철을 제외하면 감소하는 경향을 보였고 중온균과 고온성 세균의 동시 증감도 관찰되었다. 2. 중온성 방선균은 겨울철 퇴비화 초기 증가하였고 봄철 퇴비화에서는 완만하게 감소하였으나 여름철에서는 다소 감소하였다. 고온성 방선균도 퇴비화 초기에 감소하였다. 3. 중온성 사상균은 퇴비화 중기 여름철에는 감소하였으나, 봄과 겨울철에는 완만한 증가를 보였고, 고온성 사상균은 전체적으로 감소하였다. 4. 암모늄 산화세균, 아질산 산화세균은 다른 보고에서보다 상당히 많이 관찰되었다.
