Won et al. investigated the recovery of Pt from inductivelycoupled plasma (ICP) wastewater using E. coli, a byproduct ofL-phenylalanine production.163 The ICP wastewater was collectedand tested without modification. Analysis showed that itcontained 1554 ppm Pt along with a mixture of other inorganicelements. After some modification the E. coli achievedPt adsorption capacities of 108 mg g−1.
