Abstract

Biochemical and molecular studies were performed on five unknown bacterial strains isolated from the intestinal contents of Northern Bobwhites () collected from western Texas, USA. The strains were Gram-stain-positive, catalase-negative, non-spore-forming rods arranged in single cells, pairs or short chains. Colonies on Columbia blood agar are circular, flat, entire, approximately 0.5–1.5 mm in diameter and surrounded with a zone of alpha-haemolysis at after incubation for 48 h at 37 °C. Colonies on MRS agar are umbonate with irregular edge, opaque and approximately 1–1.5 mm in diameter after incubation for 48 h. The 16S rRNA gene sequences of the isolates were identical and the highest sequence similarity (97 %) was found to the type strains of , and . The strains were distinguishable from related species of the genus on the basis of carbohydrate fermentation, enzymatic production and fatty acid profiles. The peptidoglycan type is -Lys--Asp (A4α). The DNA G+C content is 35.6 mol%. Major cellular fatty acids are C, C and C ω9c. Based on phenotypic, phylogenetic and chemotaxonomic information, the strains represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is 111144 L1 (=DSM 101872=KCTC 21086).
