A New Genus of the Actinomycetales: Waksmania gen.nov.

Abstract

A single mesophilic species of a new genus belonging to the family Streptomycetaceae of the order Actinomycetales is described and has been named WAKSMANIA (W. rosea, type species). It produces a filamentous growth which is differentiated into vegetative (primary) mycelium and aerial (secondary) mycelium. Hyphae are 1.5 [mu] or less in diameter. The new genus is characterized by the production of pairs of spores which are formed either at the tip of sporophores which branch from an aerially borne hypha or directly or an aerial hypha. Spores are not formed by the vegetative mycelium.
