ABSTRACT The cultivation of halophilic microorganisms has been widely reported in liquid and semi-solid media. However, there are few reports on the use of solid fermentation for their cultivation. In the present work, t...

Abstract Background Representatives of the phylum Methanobacteriota occur in various anoxic environments, but only members of the genera Methanosphaera and Methanobrevibacter exclusively colonize the digestive tract of a...

Methane (CH4) generated during ruminal fermentation in ruminants is a major contributor to greenhouse gas emissions and represents a substantial loss of dietary energy. Therefore, mitigating enteric CH4 emissions through...

High histamine content in salted-ripened fish results in food safety detriment. The present study focused on the assembly of mixed cultures from halophilic prokaryotes isolated during salting-ripening anchovy process in ...

Monitored natural recovery (MNR) is an in situ technique of conventional remediation for the treatment of contaminated sediments that relies on natural processes to reduce the bioavailability or toxicity of contaminants....

The lung, and more specifically the airway epithelium, is continuously exposed to a wide range of inhaled environmental agents. Acting as a frontline physical and biochemical barrier, the airway epithelium orchestrates e...

The biodiversity and biotechnological potential of microbes from central Argentinean halophilic environments have been poorly explored. Salitral Negro and Colorada Grande salterns are neutral hypersaline basins exploded ...

Millions of microorganisms—including bacteria, viruses, fungi, archaea, and protists—reside on and within the human body, collectively forming the human microbiota. This complex and dynamic community plays a crucial ...

Interactions between communities of the gut microbiome and with the host could affect the onset and progression of metabolic associated fatty liver disease (MAFLD), and can be useful as new diagnostic and prognostic biom...

Background Coal seams exhibit the extensive distribution of a variety of indigenous functional microorganisms. Among these, some archaea enable methane metabolism using CO2 as a substrate, providing the potential for the...

Abstract Ornithine lipids (OLs) are phosphorus-free membrane lipids present in many bacteria, but absent from eukaryotes and archaea. Three pathways for OL synthesis have been reported to date. Conditions that induce OL ...

Abstract Lava tubes formed during the 2021 Tajogaite eruption on La Palma (Canary Islands, Spain) provide a rare opportunity to investigate the earliest stages of microbial colonization in a newly created subterranean vo...

A 16S rRNA gene database (http://greengenes.lbl.gov) addresses limitations of public repositories by providing chimera screening, standard alignment, and taxonomic classification using multiple published taxonomies. It w...

SILVA (from Latin silva, forest, http://www.arb-silva.de) is a comprehensive web resource for up to date, quality-controlled databases of aligned ribosomal RNA (rRNA) gene sequences from the Bacteria, Archaea and Eukaryo...

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide t...

16S ribosomal RNA gene (rDNA) amplicon analysis remains the standard approach for the cultivation-independent investigation of microbial diversity. The accuracy of these analyses depends strongly on the choice of primers...

Bacteria and archaea have evolved adaptive immune defenses, termed clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems, that use short RNA to direct degradation of foreign n...

BACKGROUND: The number of prokaryotic genome sequences becoming available is growing steadily and is growing faster than our ability to accurately annotate them. DESCRIPTION: We describe a fully automated service for ann...

Granites may be subdivided according to their intrusive settings into four main groups—ocean ridge granites (ORG), volcanic arc granites (VAG), within plate granites (WPG) and collision granites (COLG)—and the granit...
