Respiration by soil bacteria and fungi is one of the largest fluxes of carbon (C) from the land surface. Although this flux is a direct product of microbial metabolism, controls over metabolism and their responses to global change are a major uncertainty
Microbial carbon use efficiency promotes global soil carbon storage 微生物碳利用效率促进全球土壤碳储存 土壤比其他陆地生态系统都储存了更多的碳。土壤有机碳是如何形成和持续的仍然不确定,这使得了解它将如何应对气候变化具有挑战性。研究表明土壤微生物在土壤有机碳形成、固存和损失过程中扮演着重要角色。尽管微生...
Microbial carbon use efficiency (CUE) is a critical regulator of soil organic matter dynamics and terrestrial carbon fluxes, with strong implications for soil biogeochemistry models. While ecologists increasingly appreciate the importance of CUE, its core concepts remain ambiguous: terminology is inconsisten...
15 N-labelled maize (C/N of 25.5) and Rhodes grass (C/N of 57.8) leaf litter on microbial carbon use efficiency (CUE) and priming effects in a moderate alkaline soil at two different temperatures (15 and 25掳C). CUE values were calculated from the isotopic composition of the particulate...
Empirical evidence for the response of soil carbon cycling to the combined effects of warming, drought and diversity loss is scarce. Microbial carbon use efficiency (CUE) plays a central role in regulating the flow of carbon through soil, yet how biotic
2.6. Bacterial and fungal carbon use efficiency (CUE) Bacterial and fungal CUE of SOM and glucose were calculated from respiration rates of SOM and glucose, and the incorporation of glucose derived 13C and D2O derived D into biomarker PLFAs. Fungal and bacterial biomass C production supported by...
Responses of soil microbial carbon use efficiency to warming: Review and prospects Qiufang Zhang, Wenkuan Qin, Jiguang Feng, Biao Zhu 2022, https://doi.org/10.1007/s42832-022-0137-3 Microfluidic hotspots in bacteria research:...
Empirical evidence for the response of soil carbon cycling to the combined effects of warming, drought and diversity loss is scarce. Microbial carbon use efficiency (CUE) plays a central role in regulating the flow of carbon through soil, yet how biotic and abiotic factors interact to drive it...
Microbial carbon use efficiency (CUE) was significantly related to the variations in SOC along this national scale transect. Furthermore, the effect of climatic and edaphic factors on SOC was mainly via their regulation on microbial physiological properties (CUE and MBC). We also found that ...
Carbon (C) metabolism is at the core of ecosystem function. Decomposers play a critical role in this metabolism as they drive soil C cycle by mineralizing organic matter to CO2. Their growth depends on the carbon-use efficiency (CUE), defined as the ratio of growth over C uptake. By defin...
