Headline number from abstract: "maximum power density of 121.57 mW m⁻² (anodic volume)". Anchors the algae-sub-regime power ceiling — pairs with Salgado-Hernández 2021 current_areal anchor (1.2 A/m²) on the same Rint / CE / OCV branch parameters. | 122 mW/m² | 154 mW/m² | +26.3% | amber |

The DB extraction (120 mA/m², paperId cmcv8hx95049h1yhihhtf3819, confidence 0.5) was off by 10× due to a mA/cm² → mA/m² unit-conversion error — corrected in Wave 1.5 (codex P1). | MDC | Current density 3-chamber MDC with Chlorella vulgaris biocathode (algae-driven ORR via dissolved O2 from photosynthesis), Geobacter sulfurreducens anode, ~15 g/L NaCl desalination chamber, 31-h cycle.

CE ≈ 9% is low (vs ~60% MFC ferricyanide ceiling) because the algae-cathode ORR is rate-limited by dissolved-O₂ supply and a fraction of anode current flows to crossover / dark-phase respiration sinks. Anchors the biocathode-CE regime against Yousif 2021 aqueous CE (5.94%) and Cao 2009 ferricyanide CE (~60%). | 9.00 % | 10.9 % | +21.1% | green |
