Unlocking Mechanisms for Soil Organic Matter Accumulation: Carbon Use Efficiency and Microbial Necromass as the Keys

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

Published: Jan. 1, 2025

Soil microorganisms transform plant-derived C (carbon) into particulate organic (POC) and mineral-associated (MAOC) pools. While microbial carbon use efficiency (CUE) is widely recognized in current biogeochemical models as a key predictor of soil (SOC) storage, large-scale empirical evidence limited. In this study, we proposed experimentally tested two predictors POC MAOC pool formation: necromass (using amino sugars proxy) CUE (by 18O-H2O approach). sampling (0-10 10-20 cm depth) was conducted along climatic transect 900 km on the Loess Plateau, including cropland, grassland, shrubland, forest ecosystems, to ensure homogeneous parent material. We found highest accumulation occurred zones MAT between 5°C 10°C or MAP 300 500 mm. Microbial more positively related than (p < 0.05), suggesting that residues may improve strongly compared pool. Random linear regression analyses showed increased with fungal C, whereas bacterial drove MAOC. coupled 0.05) but decoupled SOC > 0.05).

Perspective on Lignin Conversion Strategies That Enable Next Generation Biorefineries

ChemSusChem, Journal Year: 2024, Volume and Issue: 17(16)

Published: April 26, 2024

Abstract The valorization of lignin, a currently underutilized component lignocellulosic biomass, has attracted attention to promote stable and circular bioeconomy. Successful approaches including thermochemical, biological, catalytic lignin depolymerization have been demonstrated, enabling opportunities for lignino‐refineries biorefineries. Although significant progress in made, this review describes unexplored chemical biological routes thereby contributes economically environmentally sustainable lignin‐utilizing This also highlights the integration identifies research gaps while recommending future directions scaling processes establish lignino‐chemical industry.

Microbial polyphenol metabolism is part of the thawing permafrost carbon cycle

Nature Microbiology, Journal Year: 2024, Volume and Issue: 9(6), P. 1454 - 1466

Published: May 28, 2024

Abstract With rising global temperatures, permafrost carbon stores are vulnerable to microbial degradation. The enzyme latch theory states that polyphenols should accumulate in saturated peatlands due diminished phenol oxidase activity, inhibiting resident microbes and promoting stabilization. Pairing microbiome geochemical measurements along a thaw-induced saturation gradient Stordalen Mire, model Arctic peatland, we confirmed negative relationship between expression but failed support other trends predicted by the latch. To inventory alternative polyphenol removal strategies, built CAMPER, gene annotation tool leveraging knowledge gleaned across ecosystems. Applying CAMPER genome-resolved metatranscriptomes, identified genes for diverse polyphenol-active enzymes expressed various lineages under range of redox conditions. This shifts paradigm stabilize soils highlights need consider both oxic anoxic metabolisms understand cycling changing
