Hydrothermal humification of lignocellulosic components: Who is …
NettetRecognizable lignin is present mostly in humic acid as opposed to fulvic acid fractions. This lignin component represents a source-specific and process-dependent tracer that can … NettetThe majority of these new aliphatic molecules were chemically different from aliphatic molecules already existent in the lignin precursor extract and in the P. chrysosporium biomass. Our results strongly suggest that humification by white-rot fungi in soil transforms lignin to humic substances with a predominant aliphatic character. NettetDecomposition of dead plant material causes complex organic compounds to be slowly oxidized (lignin-like humus) or to decompose into simpler forms (sugars and amino sugars, and aliphatic and phenolic organic acids), which are further transformed into microbial biomass (microbial humus) or reorganized, and further oxidized, into humic ... palliative care conference terrigal
