Due　to　the　extensive　application　of　chromate　in　industry,　chromium-contaminated　water　has　emerged　as　a　significant　hidden　danger　that　threatens　human　health　and　the　safety　of　the　ecological　environment.　The　reduction　of　Cr(VI)　to　Cr(III)　through　microbial　processes　has　become　one　of　the　most　notable　methods　for　remediating　water　polluted　by　chromium　due　to　its　economic　efficiency　and　environmentally　friendly　nature.　However,　several　issues　persist　in　its　practical　application,　such　as　low　reduction　rates,　the　need　for　additional　nutrients,　and　challenges　in　solid-liquid　separation.　Therefore,　there　is　a　growing　focus　on　seeking　enhanced　methods　for　Cr(VI)　microbial　reduction,　which　has　become　a　key　area　of　research.　This　review　represents　the　initial　effort　to　systematically　classify　and　summarize　the　means　of　enhancing　Cr(VI)　microbial　reduction.　It　categorizes　the　enhancement　methods　into　two　main　approaches:　microbial-based　and　multi-method　combined　enhancement,　offering　detailed　explanations　for　their　mechanisms.　This　research　provides　both　inspiration　and　theoretical　support　for　the　practical　implementation　of　the　Cr(VI)　microbial　reduction　method.　©　2024
