some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. those strains which have a high percentage of these features are more effective at biodegradation. the present experiments were designed to measure these parameters. in this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

The cell-surface charge and cell-surface hydrophobicity of 10 strains of Azospirillum spp. were evaluated by the aqueous, two-polymer phase partitioning assay. Azospirillum spp. had moderate cell-surface hydrophobicity and charge, lower than known values for human pathogens. The hydrophobicity and charge values were higher in solid than in liquid media. A general pattern of modifying hydrophobi...

urinary tract infections (utis) are significant health problem, with escherichia coli as the primary pathogen in proximally 80% of cases. the adhesion of e coli to the host cell can be influenced by cell surface hydrophobicity (csh) and is an important factor for the development of infections. this study was conducted to find the relation between csh and one of the adhesions (mannose resistant ...
