Using of Desulfovibrio desulfuricans in comparison with other bacterial strains
has been also demonstrated: Redwood et al. ( 2008 ) reported comparison of catalytic
efficiency of and Rhodobacter sphaeroides in dehalogenation of PCBs and penta-
CP. Gram negative (G−) and Gram positive (G+) bacterial strains D. desulfuricans
and Bacillus sphaericus took place as Pd(II) reducing agent for catalysis of itaconic
(methylene succinic) acid (Creamer et al. 2007 ). Remarkably, the same research
group published experiments in non-aqueous solvents (methanol). Specifically,
experiments leading to hydrogenations of 4-azidoaniline hydrochloride and
3-nitrostyrene, and hydrogenolysis (reductive debromination) of 1-bromo-2-ni-
trobenzene were conducted (Creamer et al. 2008 ).
Another type of G− bacteria, Shewanella oneidensis , was also used for biofabri-
cation of Pd(0) catalyst (with H 2 , formate, lactate, pyruvate or ethanol as electron
donors) for dehalogenation purpose (De Windt et al. 2005 ). The obtained bioPd(0)
NPs had the ability to reductively dehalogenate (PCB) congeners in aqueous and
sediment matrices from anonymous industrial plant. Moreover, the aforementioned
paper offers a comparison with commercially available palladium powders. Further
studies of S. oneidensis show differences between catalytic reactivity of Pd(0)
crystals formed on viable or non-viable biomass. The relatively large and densely
covering Pd(0) crystals (non-viable biomass) exhibited high catalytic reactivity
towards hydrophobic molecules such as polychlorinated biphenyls. In contrast, the
smaller and more dispersed nanocrystals on a viable bacterial carrier were catalytically
active towards anionic pollutant perchlorate (De Windt et al. 2006 ).
