Pleomorphy in Stalked, Budding Bacteria

Abstract

An investigation of hyphomicrobia from manganese deposits and various fresh-water habitats revealed an astonishing degree of pleomorphy in the group. A range of variation spanning two described genera (Hyphomicrobium and Pedomicrobium) was induced by varying culture conditions and was further observed in natural environments. It is suggested that Pedomicrobium is an invalid genus.
