Metagenomic fosmid libraries were constructed from hydrothermal chimneys and fluids and screened for hydrogen uptake (hydrogenase) activity by means of an activity-based screen. The hydrogen uptake activity of positively screened clones was determined by means of a spectrophotometric assay and the DNA-sequences of the respective fosmid inserts were determined by PacBio Sequencing. The dataset contain hydrogen-uptake activities of fosmid clones from the Sisters Peak, Nibelungen and Lilliput hydrothermal vent fields.

Metagenomic fosmid libraries were constructed from the environmental sample and screened for hydrogen uptake activity. The hydrogen upake activity of the fosmid clones has been determined as described in the cited publication.
