Diversity of bacteria and archaea from two shallow marine hydrothermal vents from Vulcano Island
TLDR
Sediment and water samples taken from two shallow marine hydrothermal vents with temperatures of 100 °C at Vulcano Island, Italy showed a high abundance of hyperthermophilic archaea and a comparable diverse archaeal community composition in both samples, and the microbial diversity of the enrichment cultures changed significantly.
Towards a sustainable biobased industry - Highlighting the impact of extremophiles.
TLDR
Further application of extremophiles has the potential to improve sustainability of existing biotechnological processes towards a greener biobased industry.
Exploration of extremophiles for high temperature biotechnological processes.
TLDR
Polysaccharide-degrading enzymes, hemicellulases, cellulases, pectinases and chitinases, lipolytic enzymes and proteases from thermophiles have attracted interest due to their potential for versatile applications in pharmaceutical, chemical, food, textile, paper, leather and feed industries as well as in biorefineries.
A model on the regulation of 3alpha-hydroxysteroid dehydrogenase/carbonyl reductase expression in Comamonas testosteroni.
TLDR
Induction of 3alpha-HSD/CR in C. testosteroni by steroids in fact appears to be a de-repression, where the steroidal 'inducer' prevents the binding of the two repressor proteins to the hsdA promoter and mRNA, respectively.
Extremely thermoactive archaeal endoglucanase from a shallow marine hydrothermal vent from Vulcano Island
TLDR
Vul_Cel5A represents a promising novel archaeal endo-β-glucanase for application in biorefineries for an efficient biomass pre-treatment and showed tolerance against various chemical reagents.
The small serine-threonine protein SIP2 interacts with STE12 and is involved in ascospore germination in Sordaria macrospora.
TLDR
The data provide evidence for a regulatory role of the novel fungal protein SIP2 in ascospore germination in a Δsip2/ste12 double knockout strain.
Digitalization in microbiology - Paving the path to sustainable circular bioeconomy.
TLDR
Challenges and opportunities of digitalization including multi-omics approaches in discovering and exploiting the microbial diversity of the planet are presented with the aim to identify robust biocatalysts for application in sustainable bioprocesses as part of the transition from a fossil-based to a bio-based circular economy.
Enrichment of anaerobic heterotrophic thermophiles from four Azorean hot springs revealed different community composition and genera abundances using recalcitrant substrates
TLDR
DGGE analysis combined with a metagenomic approach revealed that heterotrophic thermophilic bacteria are highly abundant in the hydrothermal springs and significant differences in community composition depending on the substrate were observed.
Complete genome sequence of Thermus brockianus GE-1 reveals key enzymes of xylan/xylose metabolism
TLDR
The data indicate that an ancestor of T. brockianus obtained the ability to use xylose as alternative carbon source by horizontal gene transfer and a unique genomic region on megaplasmid pTB1 was identified encoding key enzymes for xylan depolymerization andxylose metabolism.
