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...
Bacteria produce pigments for various reasons and it plays an important role. Some bacteria such as cyanobacteria have phycobilin pigments to carry out photosynthesis. Other example for pigment-producing bacterial strains includes Serratia marcescens that produces prodigiosin, Streptomyces coelicolor (prodigiosin and actinorhodin), Chromobacterium violaceum (violacein) and Thialkalivibrio versu...

Anion selective ionophores, anionophores, are small molecules capable of facilitating the transmembrane transport of anions. Inspired in the structure of natural product prodigiosin, four novel anionophores 1a-d, including a 1,2,3-triazole group, were prepared. These compounds proved highly efficient anion exchangers in model phospholipid liposomes. The changes in the hydrogen bond cleft modifi...
A high frequency of mutations affecting color production is characteristic of the HY strain of Serratia marcescens. After ultraviolet irradiation, mutants ranging from white, through pink and orange, to deep red shades darker than the wild type can be obtained (Labrum and Bunting, 1953). Many of the white and pink mutants emit diffusible substances which can be utilized by other color mutants g...
