a
The percentages of 14CO2-positive Epsilonproteobacteria with respect to total epsilonproteobacterial cell numbers and the percentages of 14CO2-positive GD17 cells with respect to total GD17 abundance are also given. Results are based, respectively, on CARD-FISH and MICRO-CARD-FISH analyses. EUB, Bacteria; EPS, Epsilonproteobacteria; —, below detection limit.
