Evolution of dimethylselenide from soils.

A J Francis, J M Duxbury, M Alexander

    Applied Microbiology
    |August 1, 1974
    PubMed
    Summary

    Dimethylselenide production in soil depends on selenium availability and microbial activity. Microbes evolved significant dimethylselenide from glucose and selenite in air, but not without selenite.

    Area of Science:

    • Environmental Chemistry
    • Microbiology
    • Geochemistry

    Background:

    • Soil microbial communities transform elements, influencing biogeochemical cycles.
    • Selenium methylation is a key process in selenium biogeochemistry.
    • Understanding microbial selenium metabolism is crucial for environmental remediation.

    Purpose of the Study:

    • To investigate the microbial production of dimethylselenide in soils.
    • To determine the influence of glucose, selenite, and oxygen on dimethylselenide evolution.
    • To identify soil properties affecting selenium methylation.

    Main Methods:

    • Incubation of glucose-amended soils under argon and air.
    • Addition of selenite to soil samples.
    • Measurement of dimethylselenide evolution using gas chromatography.

    Main Results:

    • Alcohols, carbonyl compounds, and fatty acids were produced in glucose-amended soils under argon.
    • Dimethylselenide was evolved under argon only from a selenium-rich clay soil amended with selenite and glucose.
    • Substantial dimethylselenide was released from four soils incubated with glucose and selenite in air.
    • No dimethylselenide was produced in the selenium-rich clay soil in air without selenite.

    Conclusions:

    • Microbial methylation of selenium to dimethylselenide is dependent on both selenite availability and oxygen.
    • Soil microbial communities can produce volatile selenium compounds under specific environmental conditions.
    • The presence of selenite is essential for dimethylselenide production in these soils.
