Aerobic bacterial transformation and biodegradation of dioxins: a review

open access: yesBioresources and Bioprocessing, 2020
Waste generation tends to surge in quantum as the population and living conditions grow. A group of structurally related chemicals of dibenzofurans and dibenzo-p-dioxins including their chlorinated congeners collectively known as dioxins are among the ...

Force-extension curves of bacterial flagella [PDF]

open access: yes, 2010
Bacterial flagella assume different helical shapes during the tumbling phase of a bacterium but also in response to varying environmental conditions. Force-extension measurements by Darnton and Berg explicitly demonstrate a transformation from the coiled

Analytic approach to the evolutionary effects of genetic exchange [PDF]

open access: yes, 2005
We present an approximate analytic study of our previously introduced model of evolution including the effects of genetic exchange. This model is motivated by the process of bacterial transformation.

Linkage Between Dissolved Organic Matter Transformation, Bacterial Carbon Production, and Diversity in a Shallow Oligotrophic Aquifer: Results From Flow-Through Sediment Microcosm Experiments. [PDF]

open access: yesFront Microbiol, 2020
Aquifers are important reservoirs for organic carbon. A fundamental understanding of the role of groundwater ecosystems in carbon cycling, however, is still missing.

Steady at the wheel: conservative sex and the benefits of bacterial transformation [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2016
SummaryMany bacteria are highly sexual, but the reasons for their promiscuity remain obscure. Did bacterial sex evolve to maximize diversity and facilitate adaptation in a changing world, or does it instead help to retain the bacterial functions that work right now? In other words, is bacterial sex innovative or conservative?

Biochemical Properties and Roles of DprA Protein in Bacterial Natural Transformation, Virulence, and Pilin Variation

open access: yesJournal of Bacteriology, 2023
Natural transformation enables bacteria to acquire DNA from the environment and contributes to genetic diversity, DNA repair, and nutritional requirements. DNA processing protein A (DprA) receives incoming single-stranded DNA and assists RecA loading for

Chlorine disinfection promotes the exchange of antibiotic resistance genes across bacterial genera by natural transformation

open access: yesThe ISME Journal, 2020
Chlorine disinfection to drinking water plays an important role in preventing and controlling waterborne disease outbreaks globally. Nevertheless, little is known about why it enriches the antibiotic resistance genes (ARGs) in bacteria after chlorination.

Non-antibiotic pharmaceuticals enhance the transmission of exogenous antibiotic resistance genes through bacterial transformation

open access: yesThe ISME Journal, 2020
Antibiotic resistance is a serious global threat for public health. Considering the high abundance of cell-free DNA encoding antibiotic resistance genes (ARGs) in both clinical and environmental settings, natural transformation is an important horizontal

Biophysics underlying the swarm to biofilm transition [PDF]

open access: yesScience Advances 2022, 2021
Bacteria organize in a variety of collective states, from swarming, which has been attributed to rapid surface exploration, to biofilms, which are highly dense immobile communities attributed to stress resistance. It has been suggested that biofilm and swarming are oppositely controlled, making this transition particularly interesting for understanding
