Sediment chambers without <i>U. lactuca</i> served as controls. Fluxes of ΣCO<sub>2</sub>, O<sub>2</sub>, inorganic nitrogen, and urea were determined during the incubation period in addition to sulfate reduction rates, POC and PON content, enumeration of specific bacterial populations and evaluation of the physiological state of the added <i>U. lactuca</i> thalli. After <i>U. lactuca</i> addition to the chambers, there was an immediate increase in the efflux of ΣCO<sub>2</sub> from 11 to 27 mmol-C m<sup>-2 </sup>d<sup>-1</sup> and a concomitant increase in O<sub>2</sub> uptake from 11 to 23 mmol m<sup>-2 </sup>d<sup>-1</sup>. These effluxes remained elevated throughout the incubation period. In contrast, the NH<sub>4</sub><sup>+</sup> efflux increased from 0.1 to 1.8 mmol NH<sub>4</sub><sup>+</sup> m<sup>-2 </sup>d<sup>-1</sup> during the first 3 d of incubation, followed by 6 d with a constant efflux rate, after which time it decreased gradually to 0.3 mmol NH<sub>4</sub><sup>+</sup> m<sup>-2 </sup>d<sup>-1</sup> by the end of the experiment. In total, NH<sub>4</sub><sup>+</sup> accounted for 83% of the total nitrogen efflux after addition of <i>U. lactuca</i>. During the 31 d incubation period there was a continuous colonization of the thalli by bacteria. Sulfate reducers associated with the thalli accounted for 3% of the carbon oxidation on day 31. The molar C:N ratio in mineralization products (the ratio between the efflux of ΣCO<sub>2</sub> and NH<sub>4</sub><sup>+</sup> + NO<sub>2</sub><sup>-</sup> + NO<sub>3</sub><sup>-</sup>) increased from 15 mol mol<sup>-1 </sup>at day 11 after <i>U. lactuca</i> addition to >80 mol mol<sup>-1 </sup>by the end of the incubation. Since the C:N ratio in the mineralization products was much higher than the original thallus material (8.9 mol mol<sup>-1</sup>) it is probable that a preferential incorporation of NH<sub>4</sub><sup>+</sup> into the increasing bacterial biomass occurred. The nitrogen for bacterial growth was most likely obtained from degradation of <i>U. lactuca</i> thalli as there was no stimulation of urea-N turnover in the sediment during incubation. The net increase in bacteria cell number in the 18-mm thick thallus layer was estimated to be 7.6 × 109 to 2.4 × 1010 bacterial cells cm<sup>-3</sup>. In contrast, the bacterial cell number remained constant in the -Ulva incubations.
