Microbial necromass analogues reshape composting humification pathways

Bioresource Technology
Microbial necromass is increasingly recognized as a key driver of soil carbon stabilization, yet its mechanistic role in compost humification remains elusive. Here, by integrating metagenomics, quantitative necromass tracing, and partial least squares structural equation modeling (PLS-SEM), the regulatory effects of two microbial necromass analogues-N ...

Stability of microbial necromass in soil is controlled by necromass chemical composition

Reversing the trend of decreasing soil carbon stocks is important to help mitigate current environmental challenges. Improving knowledge on the mechanisms that control the stabilisation and persistence of soil organic carbon will provide a foundation to tackle the issue.

Microbial Biomass and Necromass in Austrian Soils

Soil organic carbon (SOC) is a key indicator of healthy soils. Among the sources contributing to the SOC pool, the role of microbial biomass and especially necromass is often overlooked. Microbial necromass sometimes reaches 40 times of the microbial biomass, emphasizing the role of soil microorganisms in carbon sequestration.

Microbial necromass decomposition and stabilization in soilBai

Evidence is emerging that microbial production and residues (necromass) contribute greatly to stable soil organic matter (SOM), which calls for the necessity of separating the microbial necromass from other SOM pools in models. However, the understanding on how microbial necromass stabilizes in soil, especially the mineral protection mechanisms, is ...

Microbial Complexity and Diversity Enhance Microbial Necromass Nitrogen Sequestration Along a Latitudinal Gradient

Environmental Science & Technology
Human activities have led to nitrogen enrichments in aquatic environments, facilitating microbial nitrogen turnover and microbial necromass nitrogen (MNN) formation. The extent to which abiotic and biotic factors mediate MNN sequestration in estuarine and coastal wetlands, however, remains poorly understood.

Aligning earthworm activity and microbial necromass formation in mineral soil

2022
<p>Microbial necromass is regarded as a central pool of soil organic carbon, whose management is critical in efforts to reduce atmospheric CO<sub>2</sub> concentrations and mitigate climate change. However, recent concepts on soil organic matter formation have ignored one of the most important factors for the ...

Microbial community composition, but not diversity, influence microbial necromass mineralization

Abstract Soil harbours a wide diversity of microbes responsible for essential functions, such as depolymerizing the C and N in organic matter through the production of exoenzymes. Some of these exoenzymes are universal, whereas others are specific to certain microbes.

Patterns and controlling factors of soil microbial necromass carbon in global ecosystems

Journal of Environmental Management
Microbial necromass is a critical source of soil organic carbon (SOC) in terrestrial ecosystems, and the quantity and quality of microbial necromass carbon (MNC) can influence long-term soil carbon sequestration. However, few studies have explored the distribution of soil MNC and its contribution to SOC along the soil profiles across different ...

Rhizosphere as a hotspot for microbial necromass deposition into the soil carbon pool

Journal of Ecology
Abstract Microbial leftovers, known as necromass, are key players in storing carbon in the soil around plant roots (i.e. rhizosphere), a zone characterized by high‐efficiency microbial anabolism.
