Abstract Lichen symbioses are thought to be stabilized by the transfer of fixed carbon from a photosynthesizing symbiont fungus. In other fungal symbioses, carbohydrate subsidies correlate with reductions in plant cell wall-degrading enzymes, but whether this is true lichen symbionts (LFSs) unknown. Here, we predict genes encoding carbohydrate-active enzymes (CAZymes) and sugar transporters 46 genomes Lecanoromycetes , largest extant clade LFSs. All LFSs possess robust CAZyme arsenal...
Production of fish meal and plant-based feed proteins continues to increase meet the growing demand for seafood, leading impacts on marine terrestrial ecosystems. Microbial such as single-cell (SCPs) have been introduced alternatives since they can replace current ingredients, e.g., soybean, which are associated with negative environmental impacts. protein production also enables utilization grain processing side-streams feedstock sources. This study assesses yeast-based SCP using oat...
The Virus-X-Viral Metagenomics for Innovation Value-project was a scientific expedition to explore and exploit uncharted territory of genetic diversity in extreme natural environments such as geothermal hot springs deep-sea ocean ecosystems. Specifically, the project set analyse viral metagenomes with ultimate goal developing new gene products high innovation value applications biotechnology, pharmaceutical, medical, life science sectors. Viral pool analysis is also essential obtain...
Photosymbiodemes are a special case of lichen symbiosis where one lichenized fungus engages in with two different photosynthetic partners, cyanobacterium and green alga, to develop distinctly looking photomorphs. We compared gene expression thallus sectors the photosymbiodeme-forming Peltigera britannica containing cyanobacterial photobionts both algal investigated differential at temperatures representing mild putatively stressful conditions. First, we quantified photobiont-mediated...
Seaweeds (macroalgae) are an attractive resource for diverse microbial- and enzymatic production processes. They abundant, underutilized, cheap, rich in carbohydrates, therefore have the potential to be used as a source of mono- or oligosaccharides, substrates industrial fermentation Many seaweed polysaccharides, including sulfated polysaccharides ulvan fucoidan, however complex heterogenous structure, there currently few enzymes available modify them, understanding their depolymerization...
Werth, S., Reynisdóttir, Guðmundsson, H. & Andrésson, Ó. S. 2016. A fast and inexpensive high-throughput protocol for isolating high molecular weight genomic DNA from lichens. — Herzogia 29: 610–616.Isolating as required library preparations other applications is a challenging task. We optimized glass-fiber column-based, throughput isolation to yield comparatively large quantities of weight, pure DNA; cell lysis based on CTAB buffer was followed by centrifugation remove debris, binding...
Sulfation is gaining increased interest due to the role of sulfate in bioactivity many polysaccharides marine origin. Hence, sulfatases, enzymes that control degree sulfation, are being more extensively researched. In this work, a novel sulfatase (SulA1) encoded by gene sulA1 was characterized. The sulA1-gene located upstream chondroitin lyase encoding genome Arthrobacter strain (MAT3885). produced Escherichia coli. Based on primary sequence, enzyme classified under family 1 and two...

We investigated differential gene expression photosymbiodemes the Peltigera britannica at temperatures representing mild putatively stressful conditions compared thallus sectors containing cyanobacterial photobionts both algal photobionts. Firstly, because known ecological...

Abstract Lichen symbioses are generally thought to be stabilized by the transfer of fixed carbon compounds from a photosynthesizing unicellular symbiont fungus. In other fungal symbioses, carbohydrate subsidies correlate with genomic reductions in number genes for plant cell wall-degrading enzymes (PCWDEs), but whether this is case lichen symbionts (LFSs) unknown. We predicted encoding carbohydrate-active (CAZymes) and sugar transporters 17 existing 29 newly sequenced genomes across class...
