MicrobiologyOpen, Volume 15, Issue 1, February 2026.The Pseudomonadota are abundant and diverse members of high‐latitude soils. Here, we describe two novel species, Janthinobacterium silvisoli and Janthinobacterium saanense, of the order Burkholderiales, isolated from tundra heath and northern boreal forest soils.

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams
Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]
, 2008 Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Environmental Controls on Crenarchaeol Distributions in Hydrothermal Springs
Environmental Microbiology, Volume 28, Issue 2, February 2026.The optimal pH and temperature for crenarchaeol (a unique archaeal lipid) production in hydrothermal springs are 7.4°C and 46°C, respectively, which has important implications for archaeal evolution. Our study also indicates that pH is the most important environmental variable for archaeal lipid membrane compositions.

Freshwater Ammonia-Oxidizing Archaea Retain amoA mRNA and 16S rRNA during Ammonia Starvation [PDF]
Life, 2015 In their natural habitats, microorganisms are often exposed to periods of starvation if their substrates for energy generation or other nutrients are limiting. Many microorganisms have developed strategies to adapt to fluctuating nutrients and long-term starvation.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]
, 2009 A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Comparative analysis of ammonia monooxygenase (amoA) genes in the water column and sediment-water interface of two lakes and the Baltic Sea [PDF]
, 2008 The functional gene amoA was used to compare the diversity of ammonia-oxidizing bacteria (AOB) in the water column and sediment-water interface of the two freshwater lakes Plusssee and Schöhsee and the Baltic Sea.
