Background: Dihydrogen (H₂) natural gas is a clean and renewable energy source of significant interest in the transition to sustainable energy. Unlike conventional petroleum-based fuels, H₂ releases only water vapor upon combustion, making it a promising alternative for reducing carbon footprints in the future. However, the microbial impact on H₂ dynamics in H-emitting zones remains unclear, as does the origin of H - whether it is produced at greater depths or within shallow soil layers.

- - Biological nitrogen fixation (BNF) is crucial for providing nitrogen in tropical savannas, especially in Brazil's Cerrado, which has a conservative nitrogen cycle.
- - A long-term study explored how seasonal rainfall and nutrient additions (control, liming, nitrogen, nitrogen + phosphorus, phosphorus) affected the abundance of N-fixing bacteria related to Bradyrhizobium.
- - Results showed that as the seasons changed from rainy to dry, the amount of nitrogen-fixing genes decreased, particularly in the liming treatment, indicating that various factors influence nitrogen-fixation in these nutrient-poor and seasonally dry areas.
