Round 1: and Author Response The authors tested novel approach to identification of species in cyanobacteria based on 16S rRNA based on identification of barcoding gaps previously used in animals.
Numerous cited taxa (on the generic level) were already controlled and revised by most modern methods, and examples in the manuscript should be used especially and selected from these genera. It is true, that majority of the cited genera were already revised (Microcystis, Planktothrix, Aphanizomenon), but just these taxa are important as examples and should be preferred. From the presented results follows only the confirmation of the present methodological principles and a modern system. This fact should be emphasized.
