DESCRIPTION OF TURICIBACTER BILIS SP. NOV.

Turicibacter bilis (bi'lis. L. gen. n. bilis of bile).

Strictly anaerobic, Gram-positive, catalase-negative, non-motile, spore-forming, pleomorphic micro-organisms. Supplementation of media with 0.1% (v/v) chicken bile induces spore germination. Growth is poor in broth alone, but improves significantly in biphasic media or broth with an agar plug. Cells primarily exist as long chains of irregular rods (0.8–8.2×0.5–2.0 μm) or as individual or clusters of coccoid cells (1.0–2.3 μm). The organism is capable of growth between 30–45 °C and at pH 6.5–8.5, with optimums of 42 °C and pH 7.5, respectively. Colonies are visible on BHIGL agar after 1–2 days and appear as small to mediumsized irregularly shaped, umbonate colonies with undulating margins, with the raised centre an opaque white that transitions to a translucent tan or grey at the margins. Colonies are 2.5–5.0 mm after 3 days at 42 °C. The primary fermentation end products are acetate, butyrate and lactate. The organism is positive for arginine and gelatin biochemical reactivity.

The type strain is MMM721 T and was isolated from the surface of a chicken eggshell (= ATCC TSD-238 T = CCUG 74757 T). The genome is 2.7 Mb with a G+C content of 34.4mol% .
