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

Preventing biofilm formation using surfactants [PDF]
, 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]
European 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
Microorganisms, 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 ...

Biofilm, 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
Microbiology 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
Scientific 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 ...
