Assessment of the cyst wall and surface microbiota in dormant embryos of the Antarctic calanoid copepod, Boeckella poppei

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
A diverse microbiome colonizes the surface of dormant copepod embryos, which can survive for ~200 years in lake sediments. During dormancy, the outer two layers of a five‐layered cyst wall break apart, while the third layer remains undamaged, despite the presence of microbial species with chitinase genes.

Genome‐resolved metagenomics revealed novel microbial taxa with ancient metabolism from macroscopic microbial mat structures inhabiting anoxic deep reefs of a Maldivian Blue Hole

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
This study investigates macroscopic microbial mat structures found in complete anoxic conditions at 70 m depth in a Maldivian Blue Hole. Genome‐resolved metagenomic led to the description of several new taxa with ancient metabolism revealing novel bacterial genera belonging to the order Dehalococcoidales as dominant members of these communities ...

Distribution Patterns and Diversity of Sedimental Microbial Communities in the Tianxiu Hydrothermal Field of Carlsberg Ridge

Oceans
Hydrothermal vents, widely occurring along middle-ocean ridges and volcanic arcs, have been well-studied in vent-associated microbiology, mineralogy, and geochemistry. However, there are rarely investigations regarding the detailed microbial community in

Genomic and biogeographic characterisation of the novel prasinovirus Mantoniella tinhauana virus 1

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
Phylogenetic tree, virion morphology and global metagenomic abundance of Mantoniella tinhauana virus 1, a newly isolated and characterised prasinovirus. Abstract Mamiellophyceae are a ubiquitous class of unicellular green algae in the global ocean.

Recent Progress in the Synthesis of α‐Hydroxy Carbonyl Compounds with ThDP‐dependent Carboligases

ChemCatChem, Volume 16, Issue 15, August 12, 2024.
Building carbon connections: ThDP‐dependent carboligases are biocatalysts for the (asymmetric) synthesis of α‐hydroxy‐carbonyl compounds. In this review article we summarize recent progress on structural characterization and application of carboligases for single‐ and multi‐step reactions.

Primary to post‐depositional microbial controls on the stable and clumped isotope record of shoreline sediments at Fayetteville Green Lake

Geobiology, Volume 22, Issue 4, July/August 2024.
Abstract Lacustrine carbonates are a powerful archive of paleoenvironmental information but are susceptible to post‐depositional alteration. Microbial metabolisms can drive such alteration by changing carbonate saturation in situ, thereby driving dissolution or precipitation.

A genome catalogue of mercury‐methylating bacteria and archaea from sediments of a boreal river facing human disturbances

Environmental Microbiology, Volume 26, Issue 6, June 2024.
In this research, we broadened the understanding of the diversity among mercury methylators. We achieved this by reconstructing the metagenome‐assembled genomes derived from river sediment samples, a biome that has been underrepresented in studies.

Microbiome mediating methane and nitrogen transformations in a subterranean estuary

Environmental Microbiology, Volume 26, Issue 1, January 2024.
Our study reveals distinct microbial and biogeochemical zones in a subterranean estuary that can mediate transformations of the fluxes of greenhouse gases and nutrients. Contrary to common practices, relying solely on terrestrial endmembers to determine greenhouse gas and nutrient discharges to the coastal ocean may lead to overestimation, as our ...

Treatment of sugarcane vinasse in AnMBR and UASB: process performance and microbial community comparison

Frontiers in Bioengineering and Biotechnology
Vinasse is a by-product of sugarcane processing which is often used in fertigation; however, the direct use of vinasse harms the environment and reduces soil productivity due to its physicochemical properties.
