Second Acyl Homoserine Lactone Production System in the Extreme Acidophile Acidithiobacillus ferrooxidans
(AMER SOC MICROBIOLOGY, 2007-05)
The acidophilic proteobacterium Acidithiobacillus ferrooxidans is involved in the industrial biorecovery of copper. It is found in acidic environments in biofilms and is important in the biogeochemical cycling of metals ...
Quorum sensing en la asociación beneficiosa de las bacterias con las plantas
(Universidad Nacional de Colombia, 2011)
Título en ingles: Quorum sensing in beneficial plant-bacteria associations ResumenSe conoce que el quorum sensing es un atributo común de muchas especies bacterianas y que puede ser un carácter universal de las bacterias. ...
Biopelículas,: una comunidad microscópica en desarrollo.
(2013-11-30)
Las biopelículas son organizaciones microbianas compuestas por microorganismos que
se adhieren a las superficies gracias a la secreción de un exopolímero. Estas conformaciones
microbianas presentan características como ...
Role of non-coding regulatory RNA in the virulence of human pathogenic vibrios
(Frontiers Media, 2017)
In recent decades, the identification of small non-coding RNAs in bacteria has revealed
an important regulatory mechanism of gene expression involved in the response to
environmental signals and to the control of virulence. ...
Biofilm formation, communication and interactions of leaching bacteria during colonization of pyrite and sulfur surfaces
(Elsevier, 2014)
Bioleaching of metal sulfides is an interfacial process where biofilm formation is considered to be important in the initial steps of this process.
Among the factors regulating biofilm formation, molecular cell-to-cell ...
A lux-like quorum sensing system in the extreme acidophile Acidithiobacillus ferrooxidans
(SOCIEDAD BIOLGIA CHILE, 2005)
The genome of the acidophilic, proteobacterium Acidithiobacillus ferrooxidans, contains linked but divergently oriented genes, termed afeI and afeR, whose predicted protein products are significantly similar to the LuxI ...
Bioinformatic Prediction of Gene Functions Regulated by Quorum Sensing in the Bioleaching Bacterium Acidithiobacillus ferrooxidans
(2013)
The biomining bacterium Acidithiobacillus ferrooxidans oxidizes sulfide ores
and promotes metal solubilization. The efficiency of this process depends on the
attachment of cells to surfaces, a process regulated by quorum ...
Enzymatic hydrolysis of molecules associated with bacterial quorum sensing using an acyl homoserine lactonase from a novel Bacillus thuringiensis strain
(2014-01)
N-acyl homoserine lactones are key components of quorum sensing, the bacterial communication system. This communication mechanism regulates the expression of genes, including those involved in virulence and biofilm formation. ...
AHL communication is a widespread phenomenon in biomining bacteria and seems to be involved in mineral-adhesion efficiency
(ELSEVIER SCIENCE BV, 2008-11)
Biofilm development plays a pivotal role in the bioleaching process. Quorum sensing (QS) is recognized as
one of the main regulatory ways of extracellular polymeric substances (EPS) production and biofilm
formation in ...
