The Acidianus bottle-shaped virus, ABV, infects strains of the hyperthermophilic archaeal genus Acidianus and is morphologically distinct from all other known viruses. Its genome consists of linear double-stranded DNA, containing 23,814 bp with a G+C content of 35%, and it exhibits a 590-bp inverted terminal repeat. Of the 57 predicted ORFs, only three produced significant matches in public seq...

A Covid–19-járvány egyik makrogazdasági következménye az, hogy a világgazdaságban robusztusan növekedtek az országok bruttó külső adósságai és ennek részét képező szuverén államadósságok is. E hatás alól eurózóna tagországai sem tudták magukat kivonni. adósságok növekedése egyben azt is jelenti, elméletileg kockázatosabbá vált adósságokat finanszírozó értékpapírok (jellemzően kötvények) vásárlá...

Virus-like particles with five different morphotypes were observed in an enriched environmental sample from a hot, acidic spring (87 to 93 degrees C, pH 1.5) in Pozzuoli, Italy. The morphotypes included rigid rods, flexible filaments, and novel, exceptional forms. Particles of each type were isolated, and they were shown to represent viable virions of five novel viruses which infect members of ...

The thermoacidophilic iron-oxidizing archaeon Acidianus brierleyi is a microorganism that could be useful in the removal of inorganic As from wastewater, because it simultaneously oxidizes As(III) and Fe(II) to As(V) and Fe(III) in an acidic culture medium, resulting in the immobilization of As(V) as FeAsO₄. To investigate the oxidation mechanism, speciation of the As species in both the cells ...

UNLABELLED The field of viral metagenomics has expanded our understanding of viral diversity from all three domains of life (Archaea, Bacteria, and Eukarya). Traditionally, viral metagenomic studies provide information about viral gene content but rarely provide knowledge about virion morphology and/or cellular host identity. Here we describe a new virus, Acidianus tailed spindle virus (ATSV), ...
