Identification of microbial groups and functional genes associated with greenhouse gas emissions in prawn farms.

ABSTRACT: Understanding microbial associations with greenhouse gas (GHG) emissions is essential for promoting climate-friendly prawn production, yet it remains largely unexplored. To examine microbial-GHG relationships, this study analysed CO₂, CH₄, and N₂O emissions, characterised microbial communities, and measured the abundances of key functional genes (mcrA, pmoA, amoA, and nosZ) in water and sediment from Bangladeshi prawn farms. Results showed that microbial richness was positively correlated with CO₂ and N₂O emissions but negatively with CH₄ emissions. Methanogenic archaea, most abundant in high-salinity farms, were positively associated with CH₄ flux; however, their negative relationship with CO₂ emission
