Microbial carbon use efficiency along an altitudinal gradient [PDF]
Soil Biology and Biochemistry, 2022 Soil microbial carbon-use efficiency (CUE), described as the ratio of growth over total carbon (C) uptake, i.e. the sum of growth and respiration, is a key variable in all soil organic matter (SOM) models and critical to ecosystem C cycling. However, there is still a lack of consensus on microbial CUE when estimated using different methods. Furthermore,

Stoichiometry of microbial carbon use efficiency in soils
Ecological Monographs, 2016 AbstractThe carbon use efficiency (CUE) of microbial communities partitions the flow of C from primary producers to the atmosphere, decomposer food webs, and soil C stores. CUE, usually defined as the ratio of growth to assimilation, is a critical parameter in ecosystem models, but is seldom measured directly in soils because of the methodological ...

Beyond microbial carbon use efficiency
2023Microbial carbon use efficiency (CUE) is defined as the proportion of microbial biomass growth C versus substrate C uptake, and thus provides a useful measure of microbially driven accumulation and loss of soil organic carbon (SOC) 1. In a recent study published in Nature 2, the authors use a data-driven machine learning approach to conclude that CUE ...

Large‐scale importance of microbial carbon use efficiency and necromass to soil organic carbon
Global Change Biology, 2021AbstractOptimal methods for incorporating soil microbial mechanisms of carbon (C) cycling into Earth system models (ESMs) are still under debate. Specifically, whether soil microbial physiology parameters and residual materials are important to soil organic C (SOC) content is still unclear. Here, we explored the effects of biotic and abiotic factors on

General drivers of microbial carbon use efficiency in soils
2023The efficiency by which soil microbes direct metabolised carbon to their growth, i.e. the microbial carbon use efficiency (CUE), is hypothesised to be driven by soil pH, nutrient stoichiometry and the microbial community composition (e.g. Fungi-to-Bacteria ratio).

Microbial Carbon Use Efficiency and Growth Rates in Soil: Global Patterns and Drivers
Global Change BiologyABSTRACTCarbon use efficiency (CUE) of microbial communities in soil quantifies the proportion of organic carbon (C) taken up by microorganisms that is allocated to growing microbial biomass as well as used for reparation of cell components. This C amount in microbial biomass is subsequently involved in microbial turnover, partly leading to microbial ...

Dilemmas in Linking Microbial Carbon Use Efficiency With Soil Organic Carbon Dynamics
Global Change BiologyThere are still large uncertainties on the relationships between microbial carbon use efficiency and soil organic carbon across (1) different carbon use efficiency estimation methods, (2) various temporal, spatial and biological scales, and (3) multiple climate change scenarios.

Fractured carbonate reservoirs sweep efficiency improvement using microbial biomass
Journal of Petroleum Science and Engineering, 2013Abstract Selective plugging by microbial biomass is one of the proposed mechanisms for improving reservoir sweep efficiency in fractured reservoirs. In this study, the potential of Bacillus licheniformis strains isolated from oil contaminated soil from the Sultanate of Oman was tested for their ability to grow in induced fractures in carbonate ...

Science of The Total Environment
Root exudation and its mediated nutrient cycling process driven by nitrogen (N) fertilizer can stimulate the plant availability of various soil nutrients, which is essential for microbial nutrient acquisition. However, the response of soil microbial resource limitations to long-term N fertilizer application rates in greenhouse vegetable systems has ...
