High Biofilm Conductivity Maintained Despite Anode Potential Changes in a <i>Geobacter</i>‐Enriched Biofilm
Bibliographic record
Abstract
Abstract This study systematically assessed intracellular electron transfer (IET) and extracellular electron transfer (EET) kinetics with respect to anode potential ( E anode ) in a mixed‐culture biofilm anode enriched with Geobacter spp. High biofilm conductivity (0.96–1.24 mS cm −1 ) was maintained during E anode changes from −0.2 to +0.2 V versus the standard hydrogen electrode (SHE), although the steady‐state current density significantly decreased from 2.05 to 0.35 A m −2 in a microbial electrochemical cell. Substantial increase of the Treponema population was observed in the biofilm anode at E anode =+0.2 V, which reduced intracellular electron‐transfer kinetics associated with the maximum specific substrate‐utilization rate by a factor of ten. This result suggests that fast EET kinetics can be maintained under dynamic E anode conditions in a highly conductive biofilm anode as a result of shift of main EET players in the biofilm anode, although E anode changes can influence IET kinetics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
