A two-layer diffusion-reaction model for quantifying internal carbon loop efficiency in algal-bacterial biofilms
Algal-bacterial biofilms function as stratified microecosystems in which photosynthetic oxygen production and heterotrophic respiration are coupled through counter-diffusive \(\:{\text{O}}_{2}-{\text{C}\text{O}}_{2}\:\) transport. Quantifying this internal carbon loop is critical for designing carbon-neutral and energy...
