Down-regulation of the bacterial protein biosynthesis machinery in response to weeks, years, and decades of soil warming
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-25)How soil microorganisms respond to global warming is key to infer future soil-climate feedbacks, yet poorly understood. Here, we applied metatranscriptomics to investigate microbial physiological responses to mediumterm (8 years) and long-term (>50 years) subarctic grassland soil warming of +6°C. Besides indications for a community-wide up-regulation of centralmetabolic pathways and cell replication, ... -
Holistic Assessment of Rumen Microbiome Dynamics through Quantitative Metatranscriptomics Reveals Multifunctional Redundancy during Key Steps of Anaerobic Feed Degradation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-07)Ruminant livestock is a major source of the potent greenhouse gas methane. The complex rumen microbiome, consisting of bacteria, archaea, and microbial eukaryotes, facilitates anaerobic plant biomass degradation in the cow rumen, leading to methane emissions. Using an integrated approach combining multidomain quantitative metatranscriptomics with gas and volatile fatty acid (VFA) profiling, we ... -
Long-term warming-induced trophic downgrading in the soil microbial food web
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-01)Climatic warming has been hypothesized to accelerate organic matter decomposition by soil microorganisms and thereby enhance carbon (C) release to the atmosphere. However, the long-term consequences of soil warming on belowground biota interactions are poorly understood. Here we investigate how geothermal warming by 6 °C for more than 50 years affects soil microbiota. Using metatranscriptomics we ... -
Phylogenetic and genomic analysis of Methanomassiliicoccales in wetlands and animal intestinal tracts reveals clade-specific habitat preferences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-27)Methanogenic Thermoplasmata of the novel order Methanomassiliicoccales were recently discovered in human and animal gastro-intestinal tracts (GITs). However, their distribution in other methanogenic environments has not been addressed systematically. Here, we surveyed Methanomassiliicoccales presence in wetland soils, a globally important source of methane emissions to the atmosphere, and in the ... -
The soil microbial food web revisited: Predatory myxobacteria as keystone taxa?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-21)Trophic interactions are crucial for carbon cycling in food webs. Traditionally, eukaryotic micropredators are considered the major micropredators of bacteria in soils, although bacteria like myxobacteria and Bdellovibrio are also known bacterivores. Until recently, it was impossible to assess the abundance of prokaryotes and eukaryotes in soil food webs simultaneously. Using metatranscriptomic ... -
Thermal acclimation of methanotrophs from the genus Methylobacter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-18)Methanotrophs oxidize most of the methane (CH<sub>4</sub>) produced in natural and anthropogenic ecosystems. Often living close to soil surfaces, these microorganisms must frequently adjust to temperature change. While many environmental studies have addressed temperature effects on CH<sub>4</sub> oxidation and methanotrophic communities, there is little knowledge about the physiological adjustments ...
