this study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal ph of sheep. the surface hydrophobicity of protein increased (p

Growth of encapsulated (K+) and nonencapsulated (K-) Klebsiella pneumoniae strains in media containing sub-MICs of either cefuroxime or ciprofloxacin resulted in cell elongation but had little effect on the outer membrane protein or lipopolysaccharide profiles. Exposure to serum complement increased the surface hydrophobicity of a K- strain but failed to interact or to increase the surface hydr...

Escherichia coli surface characteristics including hydrophobicity, electrophoretic mobility and surface functional groups' composition were investigated. These characteristics were determined respectively by water contact angle measurements, microelectrophoresis and x-ray photoelectron spectroscopy (XPS). The relation between the physicochemical properties and functional groups' composition was...

The change in cell surface properties in the presence of electric currents is of critical concern when the potential to manipulate bacterial movement with electric fields is evaluated. In this study, the effects of different direct electric currents on the cell surface properties involved in bacterial adhesion were investigated by using a mixed phenol-degrading bacterial culture in the exponent...

The adhesion of Salmonella typhimurium to the mineral particles quartz, albite, feldspar, and magnetite was shown to correlate with the hydrophobicity of the cell surface as measured by hydrophobic interaction chromatography. The same effects were also seen for seven other selected test strains, including Streptococcus faecalis, Streptococcus faecium, Escherichia coli, Citrobacter freundii, Shi...

Pyocyanin is an electrochemically active metabolite produced by the human pathogen Pseudomonas aeruginosa. It is a recognized virulence factor and is involved in a variety of significant biological activities including gene expression, maintaining fitness of bacterial cells and biofilm formation. It is also recognized as an electron shuttle for bacterial respiration and as an antibacterial and ...
