Pyxidicoccus trucidator sp. nov.

Pyxidicoccus trucidator (tru.ci’da.tor L. masc. n. trucidator the slaughterer, after its widespread cytotoxicity).

Vegetative cells are Gram-negative bacilli tapering slightly at the ends, measuring 0.5–0.6 m m 3.0–6.0 m m in electron micrographs. Colonies exhibit swarming motility and appear pale brown on VY-2 agar (w/v 0.5% dried baker’s yeast, 0.1% CaCl 2 2H 2 O, and 1.5% agar). Fruiting bodies are irregular spheroids, orange in color. Aerobic growth was observed at 30–37 C, at pH 6.0–9.0, and in 0–1% NaCl. Hydrolyzes arginine, esculin, gelatin, p -nitrophenyl- B -D- galactopyranoside, and urea. Cells prey with low efficiency upon E. coli TOP 10, Cl. nebraskensis DSM 7483, and U. maydis DSM 14603.

DNA GC content is 70.3 mol%. The draft genome sequence of CA060 A T is available from GenBank (accession JAAIXZ01). The type strain ( CA060 A T ¼ NCCB 100777 T ¼ NBRC 114505 T) was isolated from soil collected in Llansteffan , UK (gridref 51.77 N 4.39 W) .
