Abstract
Worldwide usage of platinum group metals is increasing, prompting new recovery technologies. Resting cells of Desulfovibrio desulfuricans reduced soluble Pd2+ to elemental, cell-bound Pd0 supported by pyruvate, formate, or H2 as the electron donor without biochemical cofactors. Pd reduction was O2 insensitive, opening the way for recycling and recovery of Pd under oxic conditions.
摘要
全球铂族金属的使用量正在增加，这促使人们研发新的回收技术。脱硫脱硫弧菌的静止细胞能将可溶性Pd2+还原为元素态、细胞结合态的Pd0，以丙酮酸、甲酸或H2作为电子供体，无需生化辅助因子。钯的还原对氧气不敏感，这为在有氧条件下回收和再利用钯开辟了道路。
