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 ...

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Profile of Eight Prophage Sequences Present in the Genomes of Different Acinetobacter baumannii Strains

Medical Laboratory Journal, 2017
Background and Objective: Prophage sequences are major contributors to interstrain variations within the same bacterial species. Acinetobacter baumannii is a gram-negative bacterium that causes a wide range of nosocomial infections, especially in ...

AcrIIA8 is a putative phage structural protein of the HTJ2 family that does not inhibit Streptococcus pyogenes Cas9

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Anti‐CRISPR (Acr) proteins are phage‐encoded anti‐defense factors that suppress CRISPR‐Cas immunity in bacteria. AcrIIA8 was previously identified as an inhibitor of Streptococcus pyogenes Cas9 (SpyCas9) through functional assays of metagenomic libraries. Here, we report that AcrIIA8 does not inhibit SpyCas9 in biochemical assays under a range

The impact of prophages on bacterial chromosomes [PDF]

Molecular Microbiology, 2004
SummaryProphages were automatically localized in se‐quenced bacterial genomes by a simple semantic script leading to the identification of 190 prophages in 115 investigated genomes. The distribution of prophages with respect to presence or absence in a given bacterial species, the location and orientation of the prophages on the replichore was not ...

Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

Advanced Science, Volume 13, Issue 31, 4 June 2026.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...

Timely excision of prophage Φ13 is essential for the Staphylococcus aureus infectious process

Infection and Immunity
Mobile genetic elements play an essential part in the infectious process of major pathogens, yet the role of prophage dynamics in Staphylococcus aureus pathogenesis is still not well understood.

Hospital‐Associated Antimicrobial Resistant Bacteria on 95 Mobile Phones: An International Metagenomic “Phonome” Analysis

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
On average, phones harbored 3.62 of the top 10 killers and 2.49 ESKAPE organisms. In total, 667 VFGs (8621 Hits) and 262 ARGs (2475 Hits) were identified on 95 mobile phones. Mobile phones serve as a platform for horizontal gene transfer and AMR development.

Characterization of prophages of Lactococcus garvieae [PDF]

Scientific Reports, 2017
AbstractThis report describes the morphological characterization and genome analysis of an induced prophage (PLg-TB25) from a dairy strain of Lactococcus garvieae. The phage belongs to the Siphoviridae family and its morphology is typical of other lactococcal phages.
