Abstract: In nature, many microorganisms show resistance to toxic selenite by reducing selenite to non-soluble and low toxic elemental selenium. Extracellular polymeric substances (EPS), a high-molecular-weight biopolymers originated from microbial metabolism, contain many reducing groups and… read more here.

DOI: 10.3303/cet1976220
Abstract: Selenite (Se(IV)) readily bio-accumulates as compared to elemental selenium (Se(0)) which is considered to be biologically inert and relatively less toxic, therefore its microbial reduction from selenium laden waters is imperative. This study investigated the… read more here.

DOI: 10.3390/molecules27196169
Abstract: A one-pot synthesis of linear and cyclic β-alkoxyselenides is developed through the iodine-mediated three-component reaction of elemental selenium with alkenes (dienes) and alcohols. Selenylation of 1,5-hexadiene gives 2,5-di(methoxymethyl)tetrahydroselenophene and 2-methoxy-6-(methoxymethyl)tetrahydro-2H-selenopyran via the 5-exo-trig and 6-endo-trig… read more here.
