Journal ArticleDOI
Adsorption of rare earth elements onto bacterial cell walls and its implication for REE sorption onto natural microbial mats
TL;DR: In this article, the authors investigated the adsorption of rare earth elements (REE) onto the cell walls of Bacillus subtilis and Escherichia coli (a gram-negative bacterium) at various bacterial concentrations and found that the distribution coefficients of REE between the bacterial cell surface and water showed a pattern with a prominent enrichment of heavy REE (HREE), including a maximum around Sm and Eu, which was attributed to the tetrad effect.
Journal ArticleDOI
Characterization of Iron-Oxides Formed by Oxidation of Ferrous Ions in the Presence of Various Bacterial Species and Inorganic Ligands
Xavier Châtellier,M. Marcia West,Jérôme Rose,Danielle Fortin,Gary G. Leppard,F. Grant Ferris +5 more
TL;DR: In this article, the effect of inorganic ligands (PO4, SO4, or Si(OH)4) in concentrations typical of those in sediment pore waters, and of microorganisms (Escherichia coli K12, Pseudomonas aeruginosa PA01, Bacillus subtilis or Bacillus licheniformis) on the mineralogy, chemical composition, morphology and spatial distribution of the iron-oxides were examined using various complementary techniques, including TEM, XRD, and EXAFS.
Journal ArticleDOI
Effect of the presence of bacterial surfaces during the synthesis of Fe oxides by oxidation of ferrous ions
TL;DR: In this article, the effect of Bacillus subtilis and Escherichia coli on the morphology and mineralogy of Fe oxides was investigated in the presence of bacteria.
Journal ArticleDOI
Erratum to "Adsorption of rare earth elements onto bacterial cell walls and its implication for REE sorption onto natural microbial mats" (Chemical Geology 219 (1-4) (2005) 53-67)
TL;DR: Takahashi et al. as mentioned in this paper investigated the role of rare earth elements on bacterial cell walls and its implication for REE sorption onto natural microbial mats, and showed that the rare earth element can be used for bacterial cell wall adaption.
