Abstract Trophic interactions are crucial for carbon cycling in food webs. Traditionally, eukaryotic micropredators considered the major of bacteria soils, although like myxobacteria and Bdellovibrio also known bacterivores. Until recently, it was impossible to assess abundance prokaryotes eukaryotes soil webs simultaneously. Using metatranscriptomic three-domain community profiling we identified pro- 11 European mineral organic soils from different climes. Myxobacteria comprised 1.5–9.7%...
Cold-water corals in the Hola area off coast of Vesterålen (N. Norway), thrive on a substrate made methane-derived carbonate and are closely associated with microbial mats. High resolution seafloor imagery sediment samples collected during EMAN7 expedition June 2022 allowed us to reconstruct spatial relationships between methane seepage habitats gain insights into subsurface biogeochemical processes directly influencing benthic ecosystems. Here, we present fine-scale orthomosaics...
Abstract Cold seeps and cold‐water corals (CWCs) coexist on Northern Norway's continental shelf at the Hola trough between Lofoten Vesterålen. Here, cold release methane from seabed, yet none reaches sea surface. Instead, dissolves disperses in ocean where it is ultimately consumed by methane‐oxidizing microorganisms. These microorganisms metabolize carbon dioxide dissolved organic matter (DOM), which may impact biogeochemical habitat of CWCs close vicinity seeps. We investigated...
The methane-cycling microbiomes in Arctic permafrost-affected soils play crucial roles the production and consumption of this important greenhouse gas. However, little is known about distributions methanogens methanotrophs across regional scale along vertical soil profile, as well their responses to widespread permafrost thaw. Using a unique sample set from nine different locations pan-Arctic, we identified methanogen methanotroph phylotypes 729 datasets 16S rRNA gene amplicons.In 621...
The green and environmentally friendly synthesis of highly valuable organic substances is one possibility for the utilization laccases (EC 1.10.3.2). As reactants herein described syntheses, different o-substituted arylamines or arylthiols 2,5-dihydroxybenzoic acid its derivatives were used. In this way, formation phenothiazines, phenoxazines, phenazines was achieved in aqueous solution mediated by laccase Pycnoporus cinnabarinus presence oxygen. Two types phenothiazines (3-hydroxy-...
Nannochloropsis gaditana is a promising microalga for biotechnology. One of the strategies to stimulate its full potential in metabolite production exposure flashing lights. Here, we report how N. adapts different light regimes (5, 50, and 500 Hz) by changing cellular physiology relative expression genes related critical functions. We analyzed differential mRNA abundance photosynthesis, nitrogen assimilation biosynthesis chlorophyll, carotenoids, lipids, fatty acids starch. Analysis...
Abstract Trophic interactions in the microbial food web of soils are crucial for nutrient and carbon cycling. Traditionally, protozoa considered major micropredators bacteria soil. However, some prokaryotes, such as Myxobacteria Bdellovibrio also famous bacterivorous life style. Until recently, it was impossible to assess abundance pro- eukaryotic simultaneously. Using a metatranscriptomic three-domain profiling small subunit ribosomal RNA we investigated bacterivores 28 datasets from eleven...
Abstract In temperate regions, climate warming alters temperature and precipitation regimes. During winter, a decline in insulating snow cover changes the soil environment, where especially frost exposure can have severe implications for microorganisms subsequently nutrient dynamics. Here, we investigated winter change responses European beech forests microbiome. Nine study sites with each three treatments (snow exclusion, insolation, ambient) were investigated. Long‐term adaptation to...
A harmful algal bloom occurred in late spring 2019 across multiple, interconnected fjords and bays northern Norway. The event was caused by the haptophyte Chrysochromulina leadbeateri led to severe fish mortality at several salmon aquaculture facilities. This study reports on spatial temporal succession dynamics of holistic marine microbiome associated with this relating all detectable 18S 16S rRNA gene amplicon sequence variants relative abundance
Abstract Marine microalgae are a promising innovation platform for carbon capture and utilization (CCU) biotechnologies to mitigate industrial greenhouse gas emissions. However, industrial-scale cultivation of algal mono-cultures is challenging often unscalable. Non-axenic in large semi-open photobioreactors lead the co-cultivation diverse microbial communities. There limited knowledge about “bioreactor ecology” involving interacting with microbiome its subsequent impact on process stability...
Cold seeps and cold water corals (CWCs) coexist on Northern Norway's continental shelf at the Hola trough between Lofoten Vesterålen. Here, release methane from seabed, yet only a limited amount reaches atmosphere. The remaining dissolves disperses in nearby seeps. Methane is unreactive for most microorganisms column, it unique energy carbon source methane-oxidizing bacteria (MOB). MOBs metabolize dioxide as end product of oxidation. Increasing may constrain pH-sensitive CWCs...

The cruise mainly focused on two areas in the Hola Trough: at node 7 where methane seeps have been mapped, and further north (node 1) are located cold coral reefs. aim of was to characterize seafloor local biology, bubbles characteristics, water column chemistry dynamic. We also performed corals transplant study adaptation installed Piezometers temperature probes for fluid flow calculation.
