Microbiological selenate to selenite conversion for selenium removal
Selenate can be reduced to selenite mainly for respiratory processes for sustaining metabolic activity, e.g. by strain SES-3 (Oremland et al., 1994).However, in mixed cultures such as in open bioreactors, elemental selenium is the common end product of selenate reduction, with volatile methylated selenium or selenide as side products (Lenz et al., 2008b; Zehr and …

Optimized methods for detecting
Selenite F broth was our preferred option, due to a lack of availability of selenite cystine, with little difference in performance between the two being evident. The toxicity of selenite‐based media is a disadvantage, both in its powder form for inhalation and the danger it poses to aquatic life and environments.
Selenite broth: Composition, Preparation Uses
After the inoculation of the sample, selenite broth is incubated for 12-18 hours at 35°C -37°C and then subculture is done in selective agar (e.g., bismuth sulfite or desoxycholate citrate agar). Rappaport-Vassiliadis (RV) medium is now being recommended as an alternative of Selenite Broth/Tetrathionate broth for the selective enrichment of ...
