Abstract

Soil microbial necromass is an important contributor to soil organic matter (>50%) and it is largely composed of microbial residues. In soils, fragmented cell wall residues are mostly found in their polysaccharide forms of fungal chitin and bacterial peptidoglycan. Microbial necromass biomarkers, particularly amino sugars (AS) such as glucosamine (GlcN) and muramic acid (MurA) have been used to trace fungal and bacterial residues in soils, and to distinguish carbon (C) found in microbial residues from non-microbial organic C. Neutral sugars (NS), particularly the hexose/pentose ratio, have also been proposed as tracers of plant polysaccharides in soils. In our study, we extended the range of biomarkers to include AS and NS compounds in the biomass of 120 species belonging to archaea, bacteria, fungi, or plants. ...
