Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

Herbal Therapeutics in Osteoporosis: Mechanisms, Evidence, and Translational Potential

Phytotherapy Research, EarlyView.
Schematic overview of bone remodeling dysregulation in osteoporosis and the multi‐target protective role of herbal therapeutics. ABSTRACT Osteoporosis is a chronic bone disease marked by reduced density and increased fracture risk. Current treatments face limitations in safety, efficacy, and long‐term adherence, prompting interest in alternative ...

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

Small, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Bioengineered microbiotic levodopa therapy improves cognition and reduces pathology in a rat model of Alzheimer's disease

British Journal of Pharmacology, EarlyView.
Background and Purpose Degeneration of the pontine noradrenergic and midbrain dopaminergic systems contributes to cognitive‐behavioural disturbances during the prodromal stages of Alzheimer's disease (AD). We developed a genetically engineered, programmable probiotic Escherichia coli Nissle 1917 strain (EcNrhaL‐DOPA) capable of producing L‐3,4 ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

FucR Functions as a Transcriptional Regulator for L-Fucose Utilization in Campylobacter jejuni

Microorganisms
Campylobacter jejuni is an enteric pathogen and a major cause of foodborne illness worldwide. It has been shown that C. jejuni primarily utilizes amino acids as its preferred energy source, but its ability to utilize L-fucose can grant a competitive ...

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803

The FEBS Journal, EarlyView.
Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I
