An ESV is an Exact Sequence Variant. The sequence represented by an ESV is generated from a denoising algorithm. Whereas OTUs are clusters of similar sequences, ESVs are generated by examining the most abundant sequences and then removing sequences that have random differences in them as opposed to consistent differences. Those with consistent differences, even just one base difference, become their own ESV instead of being lumped together.
