Myxococcus eversor sp. nov.

Myxococcus eversor (e.ver’sor L. masc. n. eversor the destroyer, reflecting its destruction of prey cells).

Vegetative cells are Gram-negative bacilli tapering slightly at the ends, measuring 0.6–0.7 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, at pH 5.0–9.0, and with the addition of 1–4% NaCl. Hydrolyzes arginine, esculin, gelatin, p -nitrophenyl- B -D-galactopyranoside, and urea. Assimilates N -acetyl-glucosamine, adipate, arabinose, caprate, citrate, gluconate, glucose, malate, maltose, mannitol, mannose, and phenyl acetate. Cells prey with low efficiency upon E. coli TOP 10, Cl. nebraskensis DSM 7483, and U. maydis DSM 14603.

DNA GC content is 68.9 mol%. The draft genome sequence of AB053B T is available from GenBank (accession JAAIXY01). The type strain ( AB053B T ¼ NCCB 100767 T ¼ T NBRC 114350) was isolated from soil collected from Aberystwyth University , UK (gridref 52.41 N 4.08 W) .
