Outline of Final Research Achievements

Metagenomics analyses on a eutrophic lake sediment sampled from 3 stations, of which anammox activity was varied, were conducted to elucidate relationship between anammox and other functions responsible for N cycle. Abundance of anammox population linearly correlated with its activity, suggesting the population size may affect its in situ activity. On the other hand, negative correlation was found between abundance of denitrifiers and their activities. Abundance of denitrifiers in KU3, where anammox activity was highest, was significantly lower than other stations. Notably, NO reduction potential in KU3 seemed especially lower and could limit the denitrification. Relevance of this unique metabolism was discussed with respect to anammox.
