Global pattern and controls of soil microbial metabolic quotient

Ecological Monographs, 2017
AbstractThe microbial metabolic quotient (MMQ), microbial respiration per unit of biomass, is a fundamental factor controlling heterotrophic respiration, the largest carbon flux in soils. The magnitude and controls of MMQ at regional scale remain uncertain.

A metabolic quotient for methanogenic Archaea

Water Science and Technology, 2012
Biogas production from renewable resources is an alternative to generate energy and concomitantly save fossil fuels and mitigate greenhouse gas emissions. As methanogenesis is a major bottleneck in the biogas process, the determination of the specific activity of methanogenic Archaea can be a good indicator of the process state.

Microbial activity and metabolic quotient of microbes in soils amended with biochar and contaminated with atrazine and paraquat

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
The study was conducted to determine how biochar as a soil amendment maintained the microbial community in pesticide contaminated soils. Alfisol (Adenta series – Typic Kandiustalf) and Vertisol (Akuse series – Typic Calciustert) were amended with biochar

The stoichiometry of soil microbial biomass determines metabolic quotient of nitrogen mineralization

Environmental Research Letters, 2020
Soil nitrogen (N) mineralization is crucial for the sustainability of available soil N and hence ecosystem productivity and functioning. Metabolic quotient of N mineralization ( Q _min ), which is defined as net soil N mineralization per unit of soil ...

Effect of forestry practices on the biological characteristics of soils (Case study: Beech Forest of Asalem) [PDF]

مدل‌سازی و مدیریت آب و خاک, 2022
Introduction In forest management, it is essential to maintain soil performance. Forest soils control and support many forest ecosystem services and tree growth. So, maintaining soil health is critical to sustainable forest management.

Temperature legacies predict microbial metabolic quotient across forest biomes

Global Ecology and Biogeography, 2022
AbstractAimPalaeoclimate legacies have been reported to influence microbial communities and carbon (C) stocks even after thousands of years. However, the direct and indirect influences of climate legacies on microbial C processes remain poorly understood and thus limit our capacity to predict how climate legacies regulate C cycling.

Film Mulching with Low Phosphorus Application Improves Soil Organic Carbon and Its Decomposability in a Semiarid Agroecosystem

Agriculture, 2022
Soil organic carbon (SOC) storage and decomposability are crucial for soil quality. Film mulching and phosphorus (P) application are important agricultural practices on the semiarid Loess Plateau. This study analyzed the combined effects of film mulching

Probabilistic quotient’s work and pharmacokinetics’ contribution: countering size effect in metabolic time series measurements [PDF]

BMC Bioinformatics, 2022
Abstract Metabolomic time course analyses of biofluids are highly relevant for clinical diagnostics. However, many sampling methods suffer from unknown sample sizes, commonly known as size effects. This prevents absolute quantification of biomarkers.

Resting Metabolic Rate and Respiratory Quotient in Human Longevity [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2005
Significant changes in body composition, body fat distribution, and resting metabolic rate (RMR) occur with aging. Interestingly, studies on human longevity pointed out that long-lived subjects are less prone to the anthropometrics and metabolic derangement normally observed in the elderly.

Drivers of the microbial metabolic quotient across global grasslands

Global Ecology and Biogeography, 2023
AbstractAimThe microbial metabolic quotient (MMQ; mg CO2‐C/mg MBC/h), defined as the amount of microbial CO2 respired (MR; mg CO2‐C/kg soil/h) per unit of microbial biomass C (MBC; mg C/kg soil), is a key parameter for understanding the microbial regulation of the carbon (C) cycle, including soil C sequestration.
