Competitive nitrogen/phosphorus scarcity triggers multi-pathway nitrogen removal and phosphorus-stress response in microalgae-bacterial symbiosis: poly-metabolic synergy enhancement mechanisms

Key Points

• Microalgae-bacterial symbiosis effectively enhances nitrogen removal under phosphorus stress, driving ecological adaptation.
• Key evidence showed a significant increase in nitrogen removal efficiency when exposed to nutrient-scarce conditions.
• Observational analysis highlights the role of metabolic pathways, particularly nitrogen removal and phosphorus-stress responses.
• Supports the idea that microalgae-bacterial interactions may play a vital role in ecological resilience against nutrient limitations.
