Characterization of D-Arabitol as Newly Discovered Carbon Source of Bacillus methanolicus

open access: yesFrontiers in Microbiology, 2019
Bacillus methanolicus is a Gram-positive, thermophilic, methanol-utilizing bacterium. As a facultative methylotroph, B. methanolicus is also known to utilize D-mannitol, D-glucose and, as recently discovered, sugar alcohol D-arabitol.

History of Maturation of Prokaryotic Molybdoenzymes—A Personal View

open access: yesMolecules, 2023
In prokaryotes, the role of Mo/W enzymes in physiology and bioenergetics is widely recognized. It is worth noting that the most diverse family of Mo/W enzymes is exclusive to prokaryotes, with the probable existence of several of them from the earliest ...

A Quantitative Approach to Investigating the Hypothesis of Prokaryotic Intron Loss [PDF]

open access: yes, 2011
Using a novel method, we show that ordered triplets of motifs usually associated with spliceosomal intron recognition are underrepresented in the protein coding sequence of complete Thermotogae, archaeal and bacterial genomes.

The evolution of complex gene regulation by low specificity binding sites

open access: yes, 2012
Transcription factor binding sites vary in their specificity, both within and between species. Binding specificity has a strong impact on the evolution of gene expression, because it determines how easily regulatory interactions are gained and lost ...

Novel methylotrophic bacteria isolated from the River Thames (London, UK) [PDF]

open access: yes, 2008
Enrichment and elective culture for methylotrophs from sediment of the River Thames in central London yielded a diversity of pure cultures representing several genera of Gram-negative and Gram-positive bacteria, which were mainly of organisms not ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Reconstructing horizontal gene flow network to understand prokaryotic evolution

open access: yesOpen Biology, 2022
Horizontal gene transfer (HGT) is a major source of phenotypic innovation and a mechanism of niche adaptation in prokaryotes. Quantification of HGT is critical to decipher its myriad roles in microbial evolution and adaptation.

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Prokaryotic respiration and production in the meso- and bathypelagic realm of the eastern and western North Atlantic basin [PDF]

open access: yes, 2006
We measured prokaryotic production and respiration in the major water masses of the North Atlantic down to a depth of,4,000 m by following the progression of the two branches of North Atlantic Deep Water (NADW) in the oceanic conveyor belt.
