The production of color variants of Serratia marcescens by means of ultraviolet light irradiation has been reported by Labrum and Bunting (1953). These variants exhibited several shades of pink, orange, or white pigmentation, and differed markedly from the natural or wild-type red color. Rizki (1954a) demonstrated that several of these pink, orange, and white variants were capable of inducing r...

Since Pasteur first demonstrated that certain micro6rganisms are able to exert antagonistic or antibiotic effects upon other organisms, an extensive literature has accumulated (Waksman, 1941). The presence of living organisms is often necessary for the phenomenon of antagonism to take place. In many cases, the antagonist was found to produce an active substance responsible for this action. The ...

The cell surface hydrophobicity of Serratia marcescens appears to be an important factor in its adhesion to and colonization of various interfaces. The cell surface components responsible for mediating the hydrophobicity of S. marcescens have not been completely elucidated, but may include prodigiosin and other factors. In the present report we have investigated the potential role of serratamol...
