Abstract

En 中文

• A novel light-electricity-nitrogen coupling model elucidates the core microbial mechanism. • Transcriptomic analysis reveals light-induced upregulation of nitrogen transport and key metabolic genes. • Optimal light intensity (2000–5000 Lux) enables synergistic nitrogen removal (49 %) and current generation (21.05 mA/m2).
