Environmental stress response limits microbial necromass contributions to soil organic carbon
Soil Biology and Biochemistry, 2015Abstract The majority of dead organic material enters the soil carbon pool following initial incorporation into microbial biomass. The decomposition of microbial necromass carbon (C) is, therefore, an important process governing the balance between terrestrial and atmospheric C pools.

Patterns and controlling factors of soil microbial necromass carbon in global ecosystems
Journal of Environmental ManagementMicrobial 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 ...

Factors driving microbial biomass and necromass relationships display ecosystem‐dependent responses
European Journal of Soil ScienceAbstract Microorganisms help govern soil organic carbon (SOC) turnover and accumulation. Whilst it is increasingly clear that microbial necromass is a precursor of SOC formation, the relationship between living microorganisms, necromass turnover and SOC persistence remains elusive.

Science of The Total Environment
Arbuscular mycorrhizal fungi (AMF) form symbioses with most terrestrial plants and critically modulate soil organic carbon (C) dynamics. Whether AMF promote soil C storage and stability is, however, largely unknown. Since microbial necromass C (MNC) and glomalin-related soil protein (GRSP) are stable microbial-derived C in soils, we therefore evaluated

Differential contributions of microbial necromass to humic acid during composting of organic wastes
Environmental ResearchMicrobial necromass is a crucial source of stable organic matter in composting, yet its role in the humification process remains poorly understood. This study aims to explore the contribution of microbial necromass carbon (MNC) to humic acid (HA) formation during the composting of sewage sludge (SS), kitchen waste (KW), and pig manure (PM), and to ...

Soil viruses reduce greenhouse gas emissions and promote microbial necromass accrual
AbstractViral-induced microbial mortality has been proposed as a major contributor in shaping microbial community structure and function, soil carbon (C) accrual and mobilization of plant available nutrients. Yet, how soil viruses influence soil organic C (SOC) turnover and sequestration remains unknown.Xiaolong Liang +8 more
