Fe (II-III) hydroxysulphate green rust: a source of sulphate for sulphate reducing bacteria

Key Points

• Iron hydroxysulphate green rust may serve as a crucial sulphate source in specific environments, promoting bacterial activity.
• Key evidence indicates that green rust significantly influences sulphate availability, affecting local microbial communities and biogeochemical cycles.
• Analysis of microbial interactions identifies iron hydroxysulphate green rust as an electron donor for sulphate reducing bacteria in diverse ecosystems.
• Highlights the need for further exploration of iron-based compounds to understand their role in sulphate biogeochemistry.
