Xanthoferrin Siderophore Estimation from the Cell-free Culture Supernatants of Different Xanthomonas Strains by HPLC

Bio-Protocol, 2017
Xanthomonads can scavenge iron from the extracellular environment by secreting the siderophores, which are synthesized by the proteins encoded by xss (Xanthomonas siderophore synthesis) gene cluster.

ISAba1‐mediated crp‐osmC amplification enhances host‐associated fitness in Acinetobacter baumannii

mLife, EarlyView.
Abstract Acinetobacter baumannii is a pathogen, highly adaptable to both hospital‐ and host‐associated environments. Understanding the genetic mechanisms underlying its adaptability is critical for controlling its persistence. Our study identified the crp‐osmC gene cluster, flanked by ISAba1 elements, as a significant genetic structure undergoing ...

Impact of the GouM transporter on secondary metabolism activation and production yield in Streptomyces noursei strain CK‐15

New Plant Protection, EarlyView.
Overexpression of the gouM transporter gene in Streptomyces noursei CK‐15 enhances gougerotin production by 114% and activates silent biosynthetic gene clusters. This finding links transporter activity to metabolite efflux and secondary metabolism, offering a strategy for natural product discovery and strain optimization.

Combined application of Bacillus velezensis JDB15 and Trichoderma harzianum JDL4 suppresses banana Fusarium wilt under controlled conditions

Pest Management Science, EarlyView.
The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.

Quantitative Imaging of Human Hemoglobin Binding to Staphylococcus aureus With Single‐Molecule Resolution

Small, EarlyView.
Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Simultaneous modification of Thermotoga maritima encapsulin subunits to produce multivalent nanoparticle vaccines for non‐typhoidal Salmonella enterica

The FEBS Journal, EarlyView.
This study investigates the modularity of encapsulin—a protein nanoparticle—by simultaneously inserting up to four distinct Salmonella epitopes within the encapsulin subunit. The encapsulin variants were transiently expressed in plants where they assembled into nanoparticles; however, their accumulation and stability varied depending on the ...

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.
