From Lake Victoria to the Tap: Antibiotic Resistance and Pathogenic Contamination of Kisumu City Water Supply and Wastewater Network

open access: yesTropical Medicine &International Health, EarlyView.
ABSTRACT Waterborne diseases and antimicrobial resistance (AMR) pose mounting public health threats across sub‐Saharan Africa, particularly in rapidly urbanising regions dependent on untreated or poorly treated surface waters. This study applied shotgun metagenomic sequencing to characterise microbial communities, virulence factors and antibiotic ...

Tumor Cell Migration May Be an Inherent “Foraging” Behavior

open access: yesMedicine Advances, Volume 4, Issue 1, Page 103-110, March 2026.
Tumor cells gradually form pseudopodia, migrate to necrotic cells, make contact with them, and absorb necrotic cell debris. During this migration, small vesicles formed by dying tumor cells also gradually migrate toward living tumor cells. Once the nutrients from the necrotic cells have been completely absorbed, the living tumor cells will leave ...

Prokaryotic PfaB is a terminal acyltransferase that determines the final PUFA product

open access: yesProtein Science, Volume 35, Issue 3, March 2026.
Abstract Omega‐3 polyunsaturated fatty acids (PUFAs) are essential for human health due to their numerous beneficial biological properties. These compounds are synthesized in marine bacteria and eukaryotic microalgae by PUFA megasynthases (Pfas), which are evolutionarily related to fatty acid synthases (FAS) and polyketide synthases (PKS). In FAS, PKS,

Are Myxobacteria intelligent? [PDF]

open access: yesFrontiers in Microbiology, 2013
"Intelligence" is understood in different ways. Because humans are proud of their ability to speak, intelligence often includes the ability to communicate with others, to plan for the future, and to solve frequently encountered problems. Myxobacteria are among the most socially adept and ubiquitous of bacteria that live in the soil.

Seasonal Variation of Off‐Flavours in a Full‐Scale Recirculating Aquaculture System Rearing Rainbow Trout Oncorhynchus mykiss—A Case Study

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Recirculating aquaculture system (RAS) is a promising strategy for economically and environmentally sustainable fish farming. Unfortunately, microorganisms in an RAS may produce off‐flavours that accumulate in fish flesh and reduce consumer attraction for aquaculture‐produced fish. Traditionally, geosmin (GSM) and 2‐methylisoborneol (MIB), the

Porin‐Independent Uptake of Small Molecule Antibiotics Facilitated by Escherichia coli Outer Membrane Vesicles

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 1, Page 235-244, January 2026.
We demonstrate that bacterial outer membrane vesicles (OMVs) can enhance antibiotic delivery into Gram‐negative bacteria by bypassing porin‐dependent uptake. Encapsulation of imipenem in OMVs significantly increased its effectiveness against multidrug‐resistant clinical isolates, highlighting OMVs as a promising platform for overcoming permeability ...

Homoterpene Biosynthesis in Fungi

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 52, December 22, 2025.
The first homoterpene biosynthetic pathway in the fungal kingdom is reported. A methyltransferase–terpene cyclase pair produces a unique heptamethyl bicyclo[3.3.1]nonane homoterpene via presodorifen, demonstrating that homoterpene biosynthesis via the addition of a C1 unit to terpene diphosphate precursors prior to scaffold formation extends beyond the

Comparing off‐flavor trends in freshwater recirculating aquaculture systems with microbially mature or immature biofilters while growing Atlantic salmon Salmo salar

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Geosmin (GSM) and 2‐methylisoborneol (MIB) cause objectionable off‐flavors in fish produced in recirculating aquaculture systems (RAS). Remediation solutions have not been developed; therefore, a study was conducted to determine if microbial maturity limits off‐flavor production. Triplicate RAS with newly established nitrification (“immature”)

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Stereoselective Syntheses of Cyclic Microsclerodermin Derivatives

open access: yesChemistry – A European Journal, Volume 31, Issue 60, October 27, 2025.
Six different cyclic microsclerodermin derivatives are obtained from l‐xylose and d‐arabinose via stereoselective Sakurai allylations and photochemical Arndt‐Eistert homologations. Abstract Starting from l‐xylose and d‐arabinose, six different cyclic microscleroderma derivatives were successfully obtained.
