Designation of Neotype Strains for Micromonospora coerulea Jensen 1932 and Micromonospora chalcea (Foulerton 1905) Ørskov 1923

ATCC 27008 and ATCC 12452 are designated as neotype strains for Micromonospora coerulea Jensen 1932 and Micromonospora chalcea (Foulerton 1905) ørskov 1923, respectively. The data of earlier workers who studied these organisms are discussed, and additional characteristics considered useful for the identification of these species are presented.
