Description
Summary:Composting of hydrolytic lignin by a microbial association changed its molecular-weight composition, acid-base properties, and supramolecular structure. Specifically, by the end of the third month of composting, an increase was observed in its exchange capacity and the amount of negative charges, as well as in the content of phenyl, hydroxyl, and carboxyl groups. The use of this compost as a fertilizer for barley growth demonstrated that the changes increased the biological activity of hydrolytic lignin.[PUBLICATION ABSTRACT]
