GEANS paper on detection of macrobenthos species with metabarcoding: bulk DNA vs. eDNA from samples in ethanol preservative

16 November 2021 - Published by Nele Jacobs
DNA metabarcoding can be applied as a quick screening of the bentic biodiversity in a large number of samples. Certain protocol choices could however influence the detection success.


DNA extraction of the mixed sample still yields better results than just using the ethanol in which the sample was stored. The accurate identification of a species is dependent on its size and the presence of chitine or CaCO3. The choice of primer set also had a huge impact on the result. Read the full article in Frontiers in Marine Science.
