抄録/ポイント： 研究室規模の回転式微生物接触器(RBC)を利用し,廃水マトリックスに混入した酸化銅(CuO)ナノ粒子の拡散挙動や安定な廃水処理用生物膜の微生物活性に及ぼす潜在的影響を実測した。廃水試料に混入したCuOナノ粒子は質量濃度に依存して有意に凝集し,菌体外高分子物質(EPS)に吸着した銅は生物膜内に蓄積した銅全体の大部分に相当した。微小電極で濃度分布を実測し,50mg/lのCuOに1回だけパルス曝露すると,CuOナノ粒子が混入した生物膜は混入しない膜に比べ酸素が深部に拡散した。酸素消費量が最大の部位は生物膜内の深部にシフトし,生物膜の上部に生息する細菌の呼吸活性はCuOナノ粒子が有意に阻害すると示唆した。CuOナノ粒子が混入する生物膜はストレスに応答し,多量の菌体外高分子物質を排泄し,その際に多糖類に比べ蛋白質を多量に産出した。Copyright 2016 Elsevier B.V., Amsterdam.
