Soil Multi-Meta-Omics: Unraveling microbial regulation at three post-genomic levels
(2024-04-19)Soil functions are key in all ecosystems globally. Specifically soils play a pivotal role in ecosystem biogeochemical cycles, sequestering but also mineralizing carbon (C), and in this context releasing nutrients from ... -
Functions of root mucilage for plant and soil: Quantifying its exudation, characterizing its composition, and assessing its influence on plant water and nitrogen uptake and rhizosphere microorganisms
(2022-12-06)Plants modify the chemical, biological, and physical properties of the soil around their roots by releasing a set of substances called rhizodeposits. Mucilage, a viscoelastic high-molecular-weight substance exuded by ... -
Biogeochemical mechanisms of P and C cycling in rice-paddy systems driven by enzymatic reactions and the Fe(III)-Fe(II) redox wheel
(2022-11-16)Rice (Oryza sativa L.) is one of the predominant food sources and is mainly cultivated on flooded paddy soils. However, finite and dwindling phosphate rock, the main source of phosphorus (P) fertilizer, becomes increasingly ... -
Biotic and abiotic controls on microbial activity, functionality and processes in soil hotspots
(2021-08-23)When a carbon (C) source is added to a soil volume and causes microorganisms to thrive, a microbial hotspot is formed — a microsite with much higher process rates than the surrounding bulk soil. The formation, size, and ... -
Mycorrhization and Warming Modulate Soil Organic Matter Stability
(2021-06-24)Soil organic matter (SOM) is the primary source of plant-available nutrients, as well as a substantial carbon (C) reservoir in terrestrial ecosystems. Maintenance of SOM levels is therefore critical for ecosystem sustainability. ... -
Potential Impact of Increasing Ammonia Concentrations upon Microbial Population Dynamics in Anaerobic Meso- and Thermophilic driven Fermenters
(2020-02-06)Anaerobic digestion is the process of decomposition of organic matter by a microbial consortium in an oxygen-free environment. The produced biogas from this process is composed of methane, carbon dioxide, nitrogen, oxygen, ... -
Carbon Turnover in Subsoil Hotspots: Are Biopores more than Voids?
(2019-03-21)The soil below the ploughed horizon of cropland, i.e. the subsoil, could be a large sink for carbon (C) and a valuable source of mineral-bound nutrients. C dynamics in subsoils need to be thoroughly understood to enable ... -
Unfavorable environmental conditions: Consequences for microbial metabolism and C stabilization in soil
(2017-11-21)Soil microorganisms are primary drivers of biogeochemical cycles, making them an important link between pedosphere and atmosphere. Soil microbes control the carbon (C) transfer from terrestrial ecosystem to the atmosphere ...
