Strains of the genus Zoogloea Itzigsohn 1868, which now includes only one species, Zoogloea ramigera, are gramnegative aerobic chemoorganotrophic bacteria capable of forming the so-called zoogloeas, which are flocculent masses of cells embedded in gelatinous matrices and characterized bly a branched, finger-like morphology (8, 33).
