Abstract
A newly isolated actinomycete, which was recovered from a soil sample in Japan, possessed finger-shaped sporangia, motile spores and other characteristics of members of the genus Dactylosporangium. This organism produces dactimicin, a pseudodisaccharide antibiotic elaborated by at least 1 other Dactylosporangium sp. and differs significantly from the 3 previously described Dactylosporangium spp. in its production of a wine-colored pigment, which occurs in vegetative mycelium but is observed as an extracellular, diffusible substance in agar medium used to cultivate the organism. On the basis of these and other differences, it is proposed that strains with these characteristics be designated as a new species, D. vinaceum. Strain SF-2127 (= IFO 14181) is the type strain.
