Biomass conversion: fermentation chemicals and fuels.

R W Detroy, G St Julian

    Critical Reviews in Microbiology
    |January 1, 1983
    PubMed
    Summary

    Petroleum is unreliable, so researchers are exploring plant biomass, especially lignocellulose, as a renewable alternative for producing fuels and chemicals through microbial conversion.
