科普專欄–薯不揀單 - 三十秒科學–銅之鍊金細菌

金屬可以說是科技的來源。453Please respect copyright.ＰＥＮＡＮＡ2E6wj0h0aN
以銅為例，它可以製作成為各式各樣的感應器、太陽能電池、防菌薄膜等等。453Please respect copyright.ＰＥＮＡＮＡZef4Hql7RD

(圖2)近日有研究報告指出，在巴西銅礦中發現到有一品種的細菌可以從含銅的液體中提煉出銅金屬。453Please respect copyright.ＰＥＮＡＮＡNeeS6kDGQl

從圖中可見，當細菌養殖在藍綠色的CuSO4液體(含銅的液體)後48小時(攝氏28度)，液體便變成為金屬銅的銅色。453Please respect copyright.ＰＥＮＡＮＡRFNy3JCyPY

利用各種顯微鏡及相關的技術，科學家確認該細菌的確是提煉出銅金屬。453Please respect copyright.ＰＥＮＡＮＡeQCuAE3IOH

(圖3)比較兩種飼養情況，在含銅的情況下，該細菌共表達出145種正常情況下不會表達的蛋白質。453Please respect copyright.ＰＥＮＡＮＡHOHwj1S33l

暫時所假定的機制，相信是由細菌內含鐵的部份再加上檸檬酸鹽的新陳代謝協助，該細菌才得以從含銅液體中提煉出銅金屬。453Please respect copyright.ＰＥＮＡＮＡPxsVNNbdo4

若能將此投入工業化，將會大大減低提煉銅金屬所消耗的能源。453Please respect copyright.ＰＥＮＡＮＡou3lIMEEbk
