Abstract:The relative contributions to n-hexadecane mineralization by soil bacteria and fungi were assessed using the streptomycin-cycloheximide inhibition technique. In a sandy loam with no history of hydrocarbon pollution 82% n-hexadecane mineralization was attributable to bacteria and only 13% to fungi. In the same soil, glucose mineralization was shared evenly between the bacterial and fungal segments of the soil microbial community.
