Microbial Necromass in Soils—Linking Microbes to Soil Processes and Carbon Turnover

Frontiers in Environmental Science, Год журнала: 2021, Номер 9

The organic matter of living plants is the precursor material stored in terrestrial soil ecosystems. Although a great deal knowledge exists on carbon turnover processes plant material, some (SOM) formation, particular from microbial necromass, are still not fully understood. Recent research showed that larger part original converted into biomass, while remaining modified by extracellular enzymes microbes. At end its life, biomass contributes to molecular imprint SOM as necromass with specific properties. Next appropriate environmental conditions, heterotrophic microorganisms require energy-containing substrates C, H, O, N, S, P, and many other elements for growth, which provided nutrients contained SOM. As easily degradable often scarce resources soil, we can hypothesize microbes optimize their energy use. Presumably, able mobilize building blocks (mono oligomers fatty acids, amino sugars, nucleotides) stoichiometry This contrast mobilizing only consuming new synthesis primary metabolites tricarboxylic acid cycle after complete degradation substrates. Microbial thus an important resource SOM, mining could be life strategy contributing priming effects providing growth cycles. Due needs microorganisms, conclude formation through depends flux. However, details variability use decay cycles yet understood linked fields science. Here, summarize current gain, use, decay, relevant processes, e. g. pump, C storage, stabilization. We highlight factors controlling contribution implications efficiency (CUE) identify process-based modelling understanding these various types under different climates.
