A NEW ACTINOMYCETE SPECIES, NOCARDIOPSIS-LUCENTENSIS SP-NOV

A new species of the genus Nocardiopsis, for which we propose the name Nocardiopsis lucentensis sp. nov. (type strain, strain DSM 44048), wa s isolated from a salt marsh soil sample near Alicante, Spain. Whole-c ell hydrolysates contain the meso isomer of diaminopimelic acid and no characteristic sugar, thus, the cell wall composition is type III. Me naquinone MK-10(H8) is the major menaquinone, and the phospholipid typ e is type PIII (phosphatidylcholine present). Spore chains are rectifl exibilis, and in the early stages of sporulation zig-zag-shaped aerial hyphae are observed. This microorganism produces compatible solutes o f the ectoine type and is characterized by a yellowish to yellowish br own substrate mycelium and a white aerial mycelium. This organism exhi bits only 40 to 50% DNA relatedness to other Nocardiopsis spp.
