The electrohydraulic (EH) treatment of water-plant heterodisperse systems leads to the partial degradation of the main components of the plant materials: lignin, cellulose, and carbohydrates. The presence of p-hydroxyphenyl and guaiacyl structures has been established on the basis of the results of the GLC analysis of the ether-extracted phenolic products of plant materials subjected to EH treatment. It has been shown that part of the carbohydrates passes into the aqueous phase in the form of free monosaccharides: pentoses and hexoses.Institute of Chemistry of Plant Substances of Uzbekistan Academy of Sciences, Tashkent.

The pathways of the transformation of some aromatic compounds by rhe basidiomycetesPhanerochaete sanguinea andCoriolus villosus have been studied. It has been shown that the degradation of these compounds has an oxidative nature and depends on the type of substituents in the benzene ring and the propane chain. A difference has been found in the mechanisms of the reactions of the two fungi that is a consequence of the different compositions of their enzyme complexes.Wood Chemistry Division, Institute of Organic Chemistry, Siberian Division of the Russian Academy of Sciences, Irkutsk.
