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 ...

Clarification and reprogramming of glucose and xylose metabolism in Sphingomonas sanxanigenens for efficient sanxan biosynthesis

mLife, EarlyView.
Abstract Currently, the production of high‐value chemicals from natural lignocellulose is of great significance for a circular economy. In this study, a robust platform was developed based on Sphingomonas sanxanigenens NXdP, which co‐utilizes glucose and xylose to synthesize polysaccharide sanxan, for efficient bioconversion of lignocellulose‐derived ...

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 ...

Chemical characterization of exopolysaccharides from the marine fouling diatom amphora coffeaeformis

, 1996
Amphora coffeaeformis cells were grown in batch cultures under continuous illumination at 18°C for 10 d. Algal cells were removed by centrifugation, lyophilized and used for the extraction of exopolysaccharides using either 0.05 M EDTA, 1 M NaOH or 1.5 M

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...
