Pyxidicoccus caerfyrddinensis sp. nov.

Pyxidicoccus caerfyrddinensis (caer.fyrdd.in.en’sis N.L. masc. adj. caerfyrddinensis from Caerfyrddin , reflecting its isolation from soil sampled near Carmarthen [the Anglicized name for Caerfyrddin], Wales [51.86 N 4.31 W]).

Vegetative cells are Gram-negative bacilli tapering slightly at the ends, measuring 0.7–0.8 m m 3.0–8.0 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 30–40 C and at pH 6.0–9.0. Growth was unaffected by the addition of 1–3% NaCl. Hydrolyzes arginine, esculin, gelatin, p -nitrophenyl- B - D- galactopyranoside, and urea. Cells prey efficiently on Cl. nebraskensis DSM 7483, and with low efficiency upon E. coli TOP 10 and U. maydis DSM 14603.

DNA GC content is 70.2 mol%. The draft genome sequence of CA032 A T is available from GenBank (accession JAAIYA01). The type strain ( CA032 A T ¼ NCCB 100776 T ¼ NBBC 114353 T) was isolated from soil collected in Carmarthen , UK (gridref 51.86 N 4.31 W ).
