text: Microbially mediated phosphine production can be a major source of the gas in engineered systems (e.g., sewage treatment facilities and constructed wastewater treatment wetlands) where organic phosphorus is abundant and reducing conditions are common, suggesting that microbes could also play a role in phosphine formation in natural systems (although the direct enzymatic production of phosphine has not yet been identified).
