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 ...

Mycelial biomass estimation and metabolic quotient of Lentinula edodes using species-specific qPCR. [PDF]

PLoS One, 2020
Lentinula edodes, commonly known as shiitake, is an edible mushroom that is cultivated and consumed around the globe, especially in Asia. Monitoring mycelial growth inside a woody substrate is difficult, but it is essential for effective management of mushroom cultivation.

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.

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.

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.

Metabolic Quotients of the Gravid Uterus of the Chronically Catheterized Guinea Pig [PDF]

Pediatric Research, 1985
The uptake of substrates by the pregnant uterus defines the "diet" of the uterus and conceptus. In order to determine the uterine substrate uptake, catheters were placed in the femoral artery and uterine veins of guinea pigs at 40-49 days gestation.

Instability of Metabolic Quotients Obtained from Tissue Cultures.

Experimental Biology and Medicine, 1960
SummaryMaximal growth of Earle's Strain L cells is obtained by using 15-20% horse serum with a medium containing 0.5% lactalbumin hydrolysate. Rate of lactate formation decreases as pH decreases but remains constant if the suspension is adequately buffered with bicarbonate.
