Taxonomic Diversity and Antimicrobial Potential of Thermophilic Bacteria from Two Extreme Algerian Hot Springs

Microorganisms
This study investigated thermophilic bacterial communities from two Algerian hot springs: Hammam Debagh (94–98 °C), recognized as the second hottest spring in the world, and Hammam Bouhadjar (61–72 °C), one of the hottest in northwest Algeria.

Regulation of Multiple Carbon Monoxide Consumption Pathways in Anaerobic Bacteria

Frontiers in Microbiology, 2011
Carbon monoxide (CO), well known as a toxic gas, is increasingly recognized as a key metabolite and signaling molecule. Microbial utilization of CO is quite common, evidenced by the rapid escalation in description of new species of CO-utilizing bacteria ...

Screening method for dextranases and amylodextranases from anaerobic thermophiles

, 1996
Currently, there is no suitable method for screening thermophilic bacteria for dextranases (E.C. 3.2.1.11). Here we report a procedure suitable for the identification of anaerobes grown at high temperatures (55-68°C).

Evidence for horizontal gene transfer of anaerobic carbon monoxide dehydrogenases

Frontiers in Microbiology, 2012
Carbon monoxide (CO) is commonly known as a toxic gas, yet it is used by both aerobic and anaerobic bacteria and many archaea. In this study, we determined the prevalence of anaerobic carbon monoxide dehydrogenases (anaerobic CODHs, or [Ni,Fe]-CODHs) in ...

Probing the Ecological Functions of Thermophiles Using Cultivation-Dependent and Cultivation-Independent Techniques [PDF]

High-temperature geothermal springs are ecosystems that resemble early Earth, offering insights into the origins and early evolution of life. In these unique ecosystems, thermophilic microorganisms thrive.

Key role of hydrogen in regulating hydrogenases and the reductive TCA cycle in a thermophilic, autotrophic sulfur-reducing bacterium

Applied and Environmental Microbiology
Many thermophilic autotrophs in deep-sea hydrothermal vents are anaerobes that require H2 for growth. However, our understanding of how non-methanogenic thermophilic hydrogenotrophs adapt to low H2 conditions is nascent.

Novel thermophilic genera Geochorda gen. nov. and Carboxydochorda gen. nov. from the deep terrestrial subsurface reveal the ecophysiological diversity in the class Limnochordia

Frontiers in Microbiology
The class Limnochordia harbors a single cultivated member, the mesophilic Limnochorda pilosa, which was isolated from a meromictic lake. Despite numerous molecular signatures reported in various ecosystems, the ecophysiological versatility of this deeply

Phylogenomic discernments into Anaerolineaceae thermal adaptations and the proposal of a candidate genus Mesolinea

Frontiers in Microbiology
This study delves into the evolutionary history of Anaerolineaceae, a diverse bacterial family within the Chloroflexota phylum. Employing a multi-faceted approach, including phylogenetic analyses, genomic comparisons, and exploration of adaptive features,
