Sediments as Potential Sources of Non‐Cyanobacterial Diazotrophs in Arctic Sea Ice and Seawater

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Diazotrophic communities across Arctic environments: Integrated analyses of diazotrophs in sea ice, seawater, and sediments show that Arctic continental shelf sediments function as a central reservoir, supplying diazotrophs to both sea ice and seawater through resuspension processes.

Effects of biosecure macroalgae in formulated feeds on the gut bacterial microbiome of abalone Haliotis midae

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Dietary macroalgae are known to contribute directly and indirectly to the gut microflora of abalone. However, certain farms require macroalgae to be made biosecure to eliminate microbiota and reduce their risk of acting as a vector for potential disease before being included as a dietary ingredient in aquafeeds.

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

Two novel strains isolated from a brackish lake constitute Aeoliella fuhlenseeensis sp. nov. and Bythopirellula superficialaquae sp. nov. in the family Lacipirellulaceae

Scientific Reports
The strain collection of Heinz Schlesner (Kiel University, Germany) largely consists of budding bacteria collected from the 1980s to early 2000s. It still holds an untapped diversity of bacteria with uncommon morphologies and cell division modes.

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Phosphorus gradient yields threshold MAOC response governed by microbial and stoichiometric controls

Functional Ecology, Volume 40, Issue 5, Page 1369-1384, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phosphorus (P) availability is a key factor that mediates the formation of mineral‐associated organic carbon (MAOC) in soils, yet reported responses to P fertilization are often inconsistent.

Planctoellipticum variicoloris gen. nov., sp. nov., a novel member of the family Planctomycetaceae isolated from wastewater of the aeration lagoon of a sugar processing plant in Northern Germany

Scientific Reports
In the present study, we characterise a strain isolated from the wastewater aeration lagoon of a sugar processing plant in Schleswig (Northern Germany) by Heinz Schlesner. As a pioneer in planctomycetal research, he isolated numerous strains belonging to
