Research Abstract

Metagenomic studies using environment sequences reveals that huge numbers of unknown species, including completely new phylogenetic groups, existed in the eukaryotic microorganisms. On the other hand, some of taxonomically described species might be recognized as unknown organisms because their sequences data have not been accumulated. In this study, we performed trial investigations to make a comprehensive and efficient bio-profiling method for unknown, hardly culturable, or high speed swimming eukaryotic microorganisms.
