Documenting microbial populations within the University of Alberta Meteorite Curation Facility using 16S rRNA gene sequencing: Implications for the curation of astromaterials

Meteoritics &Planetary Science, Volume 60, Issue 8, Page 1798-1813, August 2025.
Abstract Meteorites are easily contaminated at the Earth's surface by microbial activity. Here, DNA extracts from two meteorite specimens and samples from curation laboratory surfaces are analyzed with amplicon sequencing, to understand microbial communities that contaminate meteorites and that may be resident in curation facilities.

Exploring the Gut and Oral Microbiomes in Psychoactive Substance Use: A Scoping Review of Clinical Studies

Journal of Neurochemistry, Volume 169, Issue 7, July 2025.
Substance use disorders are linked to high treatment dropout rates and limited therapeutic options. Clinical studies show that substance use disrupts gut and oral microbiomes, decreasing beneficial bacteria and increasing proinflammatory and opportunistic microbes.

Phylogenomic approach to integrative taxonomy resolves a century‐old taxonomic puzzle and the evolutionary history of the Acromyrmex octospinosus species complex

Systematic Entomology, Volume 50, Issue 3, Page 469-494, July 2025.
A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.

Community Composition and Metabolic Potential of Endophytic Actinobacteria From Coastal Salt Marsh Plants in Jiangsu, China

Frontiers in Microbiology, 2019
The diversity and functional roles of the plant associated endophytic actinobacteria in unique habitats remain poorly understood. In this paper, we examined the phylogenetic diversity and community composition of endophytic actinobacteria associated with

Identifizierung eines Aktivitätsselektors, der die Nitrosoaktivität in bakteriellen Typ‐III Kupferenzymen kontrolliert

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Ein kleiner, aber entscheidender Unterschied: Typ‐III‐Kupferenzyme, wie Tyrosinasen (TYRs) und o‐Aminophenoloxidasen (AOs), katalysieren die Oxidation von o‐Aminophenolen (AP) zu Chinoniminen. Im Gegensatz zu TYRs können AOs AP weiter zu Nitrosophenolen oxidieren.
