Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Defining the SOS operon of coliphage 186

, 1996
We have sequenced the LexA-controlled operon of coliphage 186 that carries the tum gene, whose product is necessary for UV induction of the 186 prophage. The operon consists of orf95 and orf97, and we have identified orf95 as the tum gene.

Probiotic Stability and Antihypertensive Activity of Peptides in Aguamiel Syrup‐Fortified Milk Protein Fermented by Lacticasebacillus rhamnosus GG

eFood, Volume 7, Issue 4, August 2026.
This study evaluates the impact of aguamiel syrup on a synbiotic fermented dairy product, focusing on antihypertensive peptide release and Lacticaseibacillus rhamnosus GG survival. While metabolic parameters remained unchanged, aguamiel syrup enhanced bioactive peptide production and antihypertensive activity (45.3%), suggesting its potential as a ...

Miniaturized Droplet‐Based Adaptation of the Ames Test for High‐Throughput Mutagenicity Assessment

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2791-2802, August 2026.
ABSTRACT This work presents the first demonstration of a tube‐based droplet microfluidic implementation of the Ames test, bridging single‐droplet resolution with regulatory genotoxicity testing. The Ames test is a cornerstone assay for detecting mutagenicity, but conventional plate‐ and well‐based formats suffer from high reagent consumption, low ...

Comprehensive Characterization of fucAO Operon Activation in Escherichia coli [PDF]

Wildtype Escherichia coli cells cannot grow on L-1,2-propanediol, as the fucAO operon within the fucose (fuc) regulon is thought to be silent in the absence of L-fucose.

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Accumulation of Histidine Reduce the Susceptibility of Vibrio splendidus Persister Cells to Tetracycline

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Histidine accumulation promotes tetracycline‐induced persister formation in V. splendidus. It enhances membrane potential and upregulating the efflux pump gene, thereby reducing antibiotic susceptibility. ABSTRACT Vibrio splendidus is an opportunistic pathogen widely distributed in marine environments, animal tissues and seabed sediments. It can infect

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...

ERF transcription factor StPti5 is a regulator of endophyte community maintenance in potato

New Phytologist, Volume 251, Issue 3, Page 1344-1360, August 2026.
Summary We have recently identified an ethylene response factor, StPti5, as a susceptibility factor that negatively regulates immune responses to diverse pathogens. Here, we investigated the role of StPti5 in the processes involved in the colonization of potato with beneficial organisms.
