Fungi　have　been　found　to　exist　in　activated　sludge　treating　saline　wastewater,　but　their　role　in　removing　pollution　has　been　neglected.　This　study　explored　the　aerobic　removal　of　total　inorganic　nitrogen　(TIN)　from　saline　wastewater　under　static　magnetic　fields　(SMFs)　with　several　strengths.　Compared　to　the　control,　the　aerobic　removal　of　TIN　was　significantly　increased　by　1.47　times　in　50　mT　SMF,　due　to　the　increased　dissimilation　nitrogen　removal　by　fungi　and　bacteria.　Under　SMF,　fungal　nitrogen　dissimilation　removal　was　significantly　increased　by　3.65　times.　The　fungal　population　size　decreased,　and　its　community　composition　changed　significantly　under　SMF.　In　contrast,　bacterial　community　composition　and　population　remained　relatively　stable.　Under　SMFs,　heterotrophic　nitrification　-　aerobic　denitrification　bacteria　Paracoccus　and　the　fungi　denitrifying　Candida　formed　a　synergistic　interaction.　This　study　elucidates　the　fungal　role　in　aerobic　TIN　removal　and　provides　an　efficient　solution　to　improve　TIN　removal　from　saline　wastewater　by　SMF.　©　2023　Elsevier　Ltd
