提出了一种利用金属离子还原菌希瓦氏藻沉积纳米铂的环保方法。当乳酸盐作为电子供体时，S. algae的静息细胞能够在室温和中性pH条件下，在60 min内将水溶液中的PtCl(6)（2-）离子还原为元素铂。约5 nm的生物源铂纳米颗粒位于周质中，这是一个较好的、易于回收生物源铂纳米颗粒的细胞表面位置。(c) 2006 Elsevier B.V.版权所有
An environmentally friendly method using the metal ion-reducing bacterium Shewanella algae was proposed to deposit platinum nanoparticles. Resting cells of S. algae were able to reduce aqueous PtCl(6)(2-) ions into elemental platinum at room temperature and neutral pH within 60 min when lactate was provided as the electron donor. Biogenic platinum nanoparticles of about 5 nm were located in the periplasm - a preferable, cell surface location for easy recovery of biogenic nanoparticles. (c) 2006 Elsevier B.V.
