Abstract
The description of the genus Kineosporia is amended after chemotaxonomic and morphological studies of the type strain of the type species, Kineosporia aurantiaca JCM 3230. This organism yielded both ll- and meso-diaminopimelic acids, which suggested that the former is present in the mycelium and the latter is present in the spores. There was no characteristic sugar pattern. A diagnostic phospholipid was phosphatidylcholine, and a major menaquinone component was MK-9(H4). No iso/anteiso branched fatty acids and no mycolic acids were observed. Colonies on agar lacked aerial mycelia, formed central projections including spores, and were occasionally accompanied by bunches of spore clusters in the agar. Spores were catenated or were located singly or aggregately at the tips of the vegetative hyphae. Our data indicate that the strain representative of the genus Kineosporia shows some similarity to the spore dome actinomycetes described by Willoughby and by Makkar and Cross.
