New Species of the Genus Actinoplanes, Actinoplanes ferrugineus

An extensive phenotypic characterization of an actinoplanete capable of producing the antimetabolite L-azetidine-2-carboxylic acid is presented. On the basis of the properties of this organism, it is concluded that it belongs to a new species, for which the name Actinoplanes ferrugineus is proposed. The type strain is X-14695 (= ATCC 29868).
