Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

Prenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

Small, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

Study on the major diazotrophs associated with Norway spruce (Picea abies L. Karst) roots [PDF]

, 2011
In this study major diazotrophs associated with medium-coarse roots of Norway spruce (Picea abies L. Karst) in a typical northern hemisphere temperate forest were investigated by applying RNA-based and protein-based methods. NifH transcripts identical to

Genomic and secondary metabolites of the marine cyanobacterium Capilliphycus salinus ALCB114379

Journal of Phycology, EarlyView.
Abstract Assembling high‐quality genomes from underexplored environments can be helpful for understanding microbial diversity and identifying novel species. The Cyanobacterium type strain Capilliphycus salinus ALCB114379 is a representative of Oscillatoriales order isolated from a supralittoral zone of the south Atlantic Ocean in Brazil, an ecotone ...

Enhanced CO2 Coordinates the Spatial Recruitment of Diazotrophs in Rice Via Root Development

Plant, Cell &Environment, Volume 49, Issue 7, Page 3678-3693, July 2026.
ABSTRACT Understanding the reciprocal interaction between root development and coadapted beneficial microbes in response to elevated CO2 (eCO2) will facilitate the identification of nutrient‐efficient cultivars for sustainable agriculture. Here, systematic morphological, anatomical, chemical and gene expression assays performed under low‐nitrogen ...

Mutagenic Survey of Key Residues of NifB Involved in Radical SAM‐Dependent Nitrogenase Cofactor Assembly

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
NifB uses an RS–K1–K2 triad to assemble the L‐cluster, a [Fe8S9C] precursor of the nitrogenase cofactor. The RS module cleaves SAM to form the 5′‐dA radical, K1 serves structural/SAM‐sensing roles, and K2 drives radical‐dependent fusion with K1. SAM‐anchoring residues link SAM binding to cluster fusion, while termini and surface residues regulate ...

Characterization and analysis of nifH genes from Paenibacillus sabinae T27

Microbiological Research, 2012
Paenibacillus sabinae T27 (CCBAU 10202=DSM 17841) is a gram-positive, spore-forming diazotroph with high nitrogenase activities. Three nifH clusters were cloned from P. sabinae T27. Phylogenetic analysis revealed that NifH1, NifH2 and NifH3 cluster with Cyanobacterium. Each of the coding regions of nifH1, nifH2 and nifH3 from P.
