Cell surface hydrophobicity of pigmented and nonpigmented clinical Serratia marcescens strains.
The cell surface hydrophobicity of 10 pigmented and 4 nonpigmented clinical Serratia marcescens strains was studied, based on the ability of the strains to adhere to hydrocarbons and to polystyrene. The cell surface hydrophobicity depended greatly on growth temperature; all of the strains tested were adherent following growth at 30 degrees C, whereas none was adherent following growth at 38 deg...
متن کاملIsolation of pigmented and nonpigmented mutants of Serratia marcescens with reduced cell surface hydrophobicity.
Enrichment for nonhydrophobic mutants of Serratia marcescens yielded two types: (i) a nonpigmented mutant which exhibited partial hydrophobic characteristics compared with the wild type, as determined by adherence to hexadecane and polystyrene; and (ii) a pigmented, nonhydrophobic mutant whose colonies were translucent with respect to those of the wild type. The data suggest that the pronounced...
متن کاملBuffering Capacity of Pigmented and Nonpigmented Strains of Serratia marcescens.
The pigmented strain Serratia marcescens ATCC 274 had a higher buffering capacity and a higher membrane H conductance than S. marcescens GP, a spontaneous nonpigmented mutant of ATCC 274. The data suggest that mutations which apparently affect only the synthesis of a secondary metabolite can modify buffering capacity and passive H conductance.
متن کاملAntibiograms and lipid contents of pigmented and nonpigmented strains of Serratia marcescens.
The antibiogram of pigmented 08 and nonpigmented Bizio strains of Serratia marcescens was determined. Their lipid content was also analyzed.
متن کاملAntibiogram and lipid analysis of a pigmented strain of Serratia marcescens and its nonpigmented variants.
Antibiograms and lipid analyses of Serratia marcescens pigmented strain 08 and its nonpigmented variants are compared. The overall lack of significant differences between pigmented and nonpigmented strains suggests that the role of pigment formation may not be related to antibiotic susceptibility.
