Description
Summary:•We monitor changes on molecular composition over the vermicompost process.•The increment of hydrophobic compounds occurs with maturation.•Microorganisms’ persistence was related with vermicompost chemical composition.•Understanding chemical nature makes possible increase vermicompost value and activity. The chemical nature of organic matter during the process of vermicomposting of cattle manure and filter cake from a sugar factory was characterized by thermochemolysis. The pyrolysates were mainly constituted of lignin moieties from propanoic acid units and short-chain (
