Five bacterial strains identified in soil samples collected at three dismissed industrial sites contaminated by heavy metals and metalloids such as lead, arsenic, and selenium were analysed for their capability to reduce the toxic oxyanion selenite (SeO32-) to the non-toxic zerovalent selenium. All isolates resulted taxonomically related to the Stenotrophomonas maltophilia species and capable of forming Senanopaticles (SeNPs).

Abstract
Five bacterial strains identified in soil samples collected at three dismissed industrial sites contaminated by heavy metals and metalloids such as lead, arsenic, and selenium were analysed for their capability to reduce the toxic oxyanion selenite (SeO32-) to the non-toxic zerovalent selenium. All isolates resulted taxonomically related to the Stenotrophomonas maltophilia species and capable of forming Senanopaticles (SeNPs).
