Adaptive laboratory evolution in Cupriavidus necator selected strain 890 that reached target cathode coverage in about one day instead of six under oxygen-limited microbial electrosynthesis.
- Why it matters: Oxic microbial electrosynthesis limits stable, electroactive cathodic biofilms due to reactive oxygen species, mass-transfer constraints, and poor stability, leaving no systematic improvement strategy.
- What they did: The team evolved cathode-colonizing populations over five passages under controlled oxygen-limited cathodic conditions, then used resequencing and a microfluidic oMES platform to characterize the dominant isolate.
- The result: Strain 890’s accelerated phenotype is linked to a single novel mutation in a bifunctional diguanylate cyclase/phosphodiesterase locus, enabling a robust biofilm at the progenitor’s steady-state biovolume.
