The Big Picture: Ocean photosynthesis is crucial for Earth’s productivity, but nutrient limitations hinder growth. Traditional solutions using synthetic chelators pose environmental risks.
The Study: Researchers developed a controlled electrochemical nutrient delivery (CEND) method using stainless-steel electrodes to provide iron to microalgae without synthetic chelators.
The Discovery: CEND achieved comparable algae growth to traditional methods without using harmful synthetic chelators.
The Takeaway: This sustainable approach could enhance marine productivity without polluting oceans. It offers a promising solution for boosting ocean health and potentially mitigating climate change.
