| Research Abstract |
The aim of this study is construction of enrichment culture of marine anammox bacteria for the development of novel nitrogen removal technology which is robust to fluctuation of environmental condition such as temperature or salinity. We succeeded the enrichment cultivation of marine anammox bacteria by using the sediment of a sea-based municipal waste disposal site as the inoculum. The enrichment culture performed stable nitrogen removal ability even under the condition of 5% salinity and less than 25℃ temperature. From bacterial community analysis, marine anammox bacteria closely related to Canidatus Scalindua and other bacteria such as sulfar-oxidizers were detected in the culture.
