微生物による有害物質の吸着に関する研究は珍しくありませんよ。酵素についてはよく分かりませんが。

Biosorption of uranium by Saccharomyces cerevisiae and surface interactions under culture conditions
http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V24-50G0DYX-9&_user=10&_coverDate=11%2F30%2F2010&_rdoc=1&_fmt=high&_orig=gateway&_origin=gateway&_sort=d&_docanchor=&view=c&_searchStrId=1692799689&_rerunOrigin=google&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=c11bdd9fdae3a152d9aab741d077f83b&searchtype=a

The maximum scavenging efficiency reached 92.4% under 6–10 h culture conditions, and the adsorption quantity of S. cerevisiae increased with initial uranium concentration. Centrifuging and drying after biosorption caused the volume reduction ratio to reach 99%. Scanning electron microscope results demonstrated that uranium interacted with yeast cell surfaces, as well as culture medium, and produced uranium precipitate on cell surfaces. Fourier transformed infrared spectra revealed that cell walls were the major sorption sites, and –Osingle bondH, –Cdouble bond; length as m-dashO and –PO2− contributed to the major binding groups.

Uranium uptake by some locally isolated and some reference bacterial species
