Abstract
By using the cyclic liquid-liquid extraction method the lignin biodegradated derivatives can be effectively extracted from the effluent liquors in ligninolytic enzymes treated kraft pulps. More than forty compounds were identified from the extractives by gas chromatography-mass spectrometry analysis. The result showed that lignin is treated with different ligninolytic enzymes, and the composition and content of the extractives differ obviously. These results suggest that the cyclic liquid-liquid extraction method can be used effectively as one new technique for the study of lignin biodegradation mechanisms.
