Phylogeny, Divergent Evolution, and Speciation of Sulfur-Oxidizing Acidithiobacillus Populations

BMC Genomics, 2019
Background Habitats colonized by acidophiles as an ideal physical barrier may induce genetic exchange of microbial members within the common communities, but little is known about how species in extremely acidic environments diverge and evolve.

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

Advanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Standardized Protocols for Soil Fauna Extraction and a Call for Cross‐Lab Implementation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We present harmonized methodologies, assembled by an international group of experts, for extracting soil‐ and litter‐inhabiting nematodes, enchytraeids, microarthropods, and larger invertebrates. The protocols are illustrated with images and videos, and include advice for overcoming the most frequent issues (’expert tips’) for increasing extraction ...

Differential gene expression and the importance of regulatory ncRNAs in acidophilic microorganisms [PDF]

, 2019
ABSTRACT Gene expression profiles provide insight into how microorganisms respond to changing environmental conditions. However, few studies have integrated expression profile analyses of both coding genes and non-coding RNAs (ncRNAs) to characterize the functional activity of microbial community members.

Fe(III) bioreduction kinetics in anaerobic batch and continuous stirred tank reactors with acidophilic bacteria relevant for bioleaching of limonitic laterites

Frontiers in Microbiology
In the framework of the H2020 project CROCODILE, the recovery of Co from oxidized ores by reductive bioleaching has been studied. The objective was to reduce Fe(III) to Fe(II) to enhance the dissolution of Co from New-Caledonian limonitic laterites ...
