Methylmercury in Antarctic Krill Microbiomes
Listed in NASA Earthdata CMR
The goal of this project was to conduct a preliminary assessment of gut microbiomes in Antarctic krill (Euphasia superba) collected in coastal waters west of the Antarctic Peninsula and identify organisms potentially capable of catalyzing the production of methylmercury.
Description
DNA was extracted from composite krill digestive tracts and eukaryotic DNA removed. Prokaryotic microbial DNA extracted from krill digestive tracts was sequenced and gene libraries were constructed.
Genera of anaerobic microorganisms which are known to support mercury methylation were identified.
