| Outline of Final Research Achievements |
Microbial loop which is driven by bacterial (secondary) production based on dissolved organic matter plays an important role in lake ecosystems. This study evaluated the sources of dissolved organic matter flowing into microbial loop and bacterial community utilizing the dissolved organic matter in Lake Inba, Chiba prefecture. The results suggest that Burkholderiales are likely to contribute to microbial loop in Lake Inba in different seasons. One of the possible sources of dissolved organic matter supporting bacterial production in Inba lake is inflowing river.
