The investigation of microbiological succession and changes in the enzymatic activity, temperature, pH, and phytotoxicity of lignin during its composting showed that the addition of a starter culture (a specially developed association of microorganisms) affects degradational succession in the compost pile. The process of composting can be monitored either microbiologically or biochemically, by measuring the activity of some enzymes. The compost is ready for use when the activity of oxidoreductases (particularly polyphenol oxidases) falls and the activity of invertase stabilizes at a certain level. 相似文献

Composting of hydrolytic lignin by a microbial association changed its molecular-weight composition, acid-based 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. 相似文献

Microbial assemblages were composed for composting hydrolyzed lignin. Data on bioconversion of aromatic compounds with various
types of substitution in die ring were used for this purpose. Composting of hydrolyzed lignin reduced the contents of lignin,
low-hydrolyzable polysaccharides, resins, and low-molecularweight phenols and resulted in accumulation of humic acids. The
resulting compost showed no phytotoxicity. 相似文献
