In this study, the picocyanobacterial species composition of Lake Miyagase was examined by analyzing the 16S rRNA gene in a clone library and by amplicon sequencing using a benchtop next-generation sequencer. Five separate samples were analyzed from different days over a ten-month period. In the picocyanobacterial lineage, 9 and 12 OTUs were identified from a clone library and by amplicon sequencing, respectively. Both analyses suggested that a picocyanobacterium related to Synechococcus sp. MW6B4 was dominant in Lake Miyagase. Our findings suggest that 16S rRNA gene amplicon sequencing enables detailed evaluation of picocyanobacteria composition. One OTU identified was found to be a novel cluster that does not group with any of the known freshwater picocyanobacteria.
