Abstract

A new genus, , is proposed for a group of flat, six-pronged star-shaped prosthecobacteria found in freshwater, soil, and sewage in widely separated geographical areas. The morphology of the cells provides clear differentiation from all other eubacteria. The cellular morphology and mode of multiplication of these organisms also provide clear separation from other budding and appendaged prosthecobacteria. The cells are gram negative, flat, nonmotile, and asporogenic. Representative organisms in the genus are chemoorganotrophic, growing on low nutrient concentrations and utilizing a variety of amino acids and organic acids. Two distinct species are recognized. (type species) is an avacuolate organism, and the type strain (strain AUCM B-1137) has been deposited in the All Union Collection of Microorganisms, Moscow, USSR, and in the Institute of Microbiology, Academy of Sciences, Moscow, USSR. is a gas vacuolate prosthecobacterium, and the type strain is strain 229 (Institute of Microbiology, Academy of Sciences, Moscow, USSR). Organisms in the genus appear to represent the first example of radial symmetry in procaryotic cells.
