Methylation of arsenic by anaerobic microbial consortia isolated from lake sediment
Autor: Doug A. Bright, Kenneth J. Reimer, S. Brock, Gary M. Hewitt, J. Jafaar, William R. Cullen
Publikováno v: Applied Organometallic Chemistry. 8:415-422
Anaerobic enrichment cultures, isolated from arsenic–contaminated lake sediment in the Canadian sub–arctic and grown in five selective media, methylated arsenate/arsenite to produce mono−, di− and tri–methyl arsenicals. The extent of methyl

Bioaccumulation and excretion of arsenic compounds by a marine unicellular alga,polyphysa peniculus
Autor: Hao Li, Gary M. Hewitt, Lionel G. Harrison, William R. Cullen
Publikováno v: Applied Organometallic Chemistry. 8:313-324
Polyphysa peniculus was grown in artificial seawater in the presence of arsenate, arsenite, monomethylarsonate and dimethylarsinic acid. The separation and identification of some of the arsenic species produced in the cells as well as in the growth m
