Plant grown inhibitors of low molecular weight and high molecular weight were detected in water extract of sawdust of American hemlock. During maturation of compost containing sawdust of American hemlock, these inhibitors disappeared. Five microorganisms isolated from the compost were able to grow on minimal agar plate containing the inhibitors as the sole carbon source. These microorganisms decomposed the plant growth inhibitors of high molecular weight in sawdust of American hemlock as well as the extracted inhibitors.
