There　has　been　a　trend　towards　the　use　of　microorganisms　to　recover　metals　from　industrial　wastewater,　for　which　various　methods　have　been　reported　to　be　used　to　improve　microorganism　adsorption　characteristics　such　as　absorption　capacity,　tolerance　and　reusability.　In　present　study,　chlorine　dioxide(ClO2),　a　high-efficiency,　low　toxicity　and　environment-benign　disinfectant,　was　first　reported　to　be　used　for　microorganism　surface　modification.　The　chlorine　dioxide　modified　cells　demonstrated　a　10.1%　higher　uranium　adsorption　capacity　than　control　ones.　FTIR　analysis　indicated　that　several　cell　surface　groups　are　involved　in　the　uranium　adsorption　and　cell　surface　modification.　The　modified　cells　were　further　immobilized　on　a　carboxymethylcellulose(CMC)　matrix　to　improve　their　reusability.　The　cell-immobilized　adsorbent　could　be　employed　either　in　a　high　concentration　system　to　move　vast　UO22+　ions　or　in　a　low　concentration　system　to　purify　UO22+　contaminated　water　thoroughly,　and　could　be　repeatedly　used　in　multiple　adsorption-desorption　cycles　with　about　90%　adsorption　capacity　maintained　after　seven　cycles.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
