Fig. 5: Cell-specific power requirement of AOA in marine oxic sediements.
From: Ammonia-oxidizing archaea have similar power requirements in diverse marine oxic sediments
Cell-specific power requirement of AOA are plotted as a function of sediment depth (A) and of the relative depth in the oxic zone (B). Error bars represent the 95% of confidence level, derived from the AOA cell abundance estimation as presented in Fig. 4A. The cross symbol (×) in (A) represents the values calculated for bulk cells that were assumed to catalyze the aerobic degradation of POC in core SPG_U1370 [11]. In both panels, the gray box represents the cell-specific power requirement range calculated for AOA strained grown in the laboratory based on the cell-specific data reported in [29, 51, 52] (see “Materials and methods” for details). The vertical dashed line refers to the value of marine ammonia-oxidizing bacterium Nitrosomonas marina calculated by [10, 53] based on the chemostat experiment data reported in [54].
