The protein tyrosine kinases EpsB and PtkA differentially affect biofilm formation in Bacillus subtilis [PDF]

open access: yes, 2014
The Gram-positive soil bacterium Bacillus subtilis is able to choose between motile and sessile lifestyles. The sessile way of life, also referred to as biofilm, depends on the formation of an extracellular polysaccharide matrix and some extracellular ...

Culexarchaeia, a novel archaeal class of anaerobic generalists inhabiting geothermal environments

open access: yesISME Communications, 2022
Geothermal environments, including terrestrial hot springs and deep-sea hydrothermal sediments, often contain many poorly understood lineages of archaea.

Preventing biofilm formation using surfactants [PDF]

open access: yes, 2007
Microbial adhesion to abiotic surfaces and consequent biofilm formation has been documented in many environments. In many technical processes, the presence of microorganisms is acceptable as long as they remain planktonic.

Biofilms and their properties [PDF]

open access: yesEuropean Journal of Oral Sciences, 2018
Bacteria within the oral cavity live primarily as complex, polymicrobial biofilms. Dental biofilms are necessary etiological factors for dental caries and periodontal diseases but have also been implicated in diseases outside the oral cavity. Biofilm is the preferred lifestyle for bacteria, and biofilms are found on almost any surface in nature ...

Low-Temperature Biosurfactants from Polar Microbes

open access: yesMicroorganisms, 2020
Surfactants, both synthetic and natural, are used in a wide range of industrial applications, including the degradation of petroleum hydrocarbons. Organisms from extreme environments are well-adapted to the harsh conditions and represent an exciting ...

Diversity and function of methyl-coenzyme M reductase-encoding archaea in Yellowstone hot springs revealed by metagenomics and mesocosm experiments

open access: yesISME Communications, 2023
Metagenomic studies on geothermal environments have been central in recent discoveries on the diversity of archaeal methane and alkane metabolism. Here, we investigated methanogenic populations inhabiting terrestrial geothermal features in Yellowstone ...

Mycobacterium biofilms

open access: yesBiofilm, 2023
The genus Mycobacterium includes some of the deadliest pathogens of History (Mycobacterium tuberculosis, Mycobacterium leprae), but most of the species within the genus are environmental microorganisms. Because some of these nontuberculous mycobacteria (NTM) species can be human pathogens, the study of these mycobacterial biofilms has increased during ...

Inoculum Concentration Influences Pseudomonas aeruginosa Phenotype and Biofilm Architecture

open access: yesMicrobiology Spectrum, 2022
In infections, bacterial cells are often found as relatively small multicellular aggregates characterized by a heterogeneous distribution of phenotype, genotype, and growth rates depending on their surrounding microenvironment.

Reproducibility of antimicrobial test methods

open access: yesScientific Reports, 2018
We review reproducibility results for methods that test antimicrobial efficacy against biofilms, spores and bacteria dried onto a surface. Our review, that included test results for Pseudomonas aeruginosa, Salmonella choleraesuis and Bacillus subtilis ...

Protocol to assess metabolic activity of Pseudomonas aeruginosa by measuring heat flow using isothermal calorimetry

open access: yesSTAR Protocols, 2023
Summary: Here, we present a protocol for assessing metabolic activity of bacterial populations by measuring heat flow using isothermal calorimetry. We outline the steps for preparing the different growth models of Pseudomonas aeruginosa and performing ...
