<jats:title>ABSTRACT</jats:title>
<jats:p>
Recent studies have indicated that chemoautotrophic
<jats:italic>Epsilonproteobacteria</jats:italic>
might play an important role, especially as anaerobic or microaerophilic dark CO
<jats:sub>2</jats:sub>
-fixing organisms, in marine pelagic redoxclines. However, knowledge of their distribution and abundance as actively CO
<jats:sub>2</jats:sub>
-fixing microorganisms in pelagic redoxclines is still deficient. We determined the contribution of
<jats:italic>Epsilonproteobacteria</jats:italic>
to dark CO
<jats:sub>2</jats:sub>
fixation in the sulfidic areas of central Baltic Sea and Black Sea redoxclines by combining catalyzed reporter deposition-fluorescence in situ hybridization with microautoradiography using [
<jats:sup>14</jats:sup>
C]bicarbonate and compared it to the total prokaryotic chemoautotrophic activity. In absolute numbers, up to 3 × 10
<jats:sup>5</jats:sup>
<jats:sup>14</jats:sup>
CO
<jats:sub>2</jats:sub>
-fixing prokaryotic cells ml
<jats:sup>−1</jats:sup>
were enumerated in the redoxcline of the central Baltic Sea and up to 9 × 10
<jats:sup>4</jats:sup>
<jats:sup>14</jats:sup>
CO
<jats:sub>2</jats:sub>
-fixing cells ml
<jats:sup>−1</jats:sup>
were enumerated in the Black Sea redoxcline, corresponding to 29% and 12%, respectively, of total cell abundance.
<jats:sup>14</jats:sup>
CO
<jats:sub>2</jats:sub>
-incorporating cells belonged exclusively to the domain
<jats:italic>Bacteria</jats:italic>
. Among these, members of the
<jats:italic>Epsilonproteobacteria</jats:italic>
were approximately 70% of the cells in the central Baltic Sea and up to 100% in the Black Sea. For the Baltic Sea, the
<jats:italic>Sulfurimonas</jats:italic>
subgroup GD17, previously assumed to be involved in autotrophic denitrification, was the most dominant CO
<jats:sub>2</jats:sub>
-fixing group. In conclusion,
<jats:italic>Epsilonproteobacteria</jats:italic>
were found to be mainly responsible for chemoautotrophic activity in the dark CO
<jats:sub>2</jats:sub>
fixation maxima of the Black Sea and central Baltic Sea redoxclines. These
<jats:italic>Epsilonproteobacteria</jats:italic>
might be relevant in similar habitats of the world's oceans, where high dark CO
<jats:sub>2</jats:sub>
fixation rates have been measured.
