Outline of Final Research Achievements |
This study aims to explore the relationships between soil microbes and small animals living in the soil, with hopes of developing novel microbial bioresources derived from soil animals. In this study, five species of oribatid mites (Acari: Oribatida) were used as model soil animals. Bacteria were isolated from these animals, and bacterial community structure was analyzed. Based on the results from meta-16S rRNA gene sequence analysis, I revealed large differences in bacterial diversity among oribatid mite species. In addition, a relatively large number of novel bacterial strains were isolated from Trhypochthonius species samples. Some of the isolates were novel bacterial strains that can only be cultured under a co-culture condition with specific bacterial strains. These novel bacterial strains were deposited into the JCM culture collection and will be used as novel bacterial bioresources.
