Jr. Lloyd et al., ENZYMATIC RECOVERY OF ELEMENTAL PALLADIUM BY USING SULFATE-REDUCING BACTERIA, Applied and environmental microbiology (Print), 64(11), 1998, pp. 4607-4609
Worldwide usage of platinum group metals is increasing, prompting new
recovery technologies. Resting cells of Desulfovibrio desulfuricans re
duced soluble Pd2+ to elemental, cell-bound Pd-0 supported by pyruvate
, formate, or H-2 as the electron donor without biochemical cofactors.
Pd reduction was O-2 insensitive, opening the way for recycling and r
ecovery of Pd under oxic conditions.
