Cells of strain 10CT were Gram-positive, motile rods, and grew optimally at 45 °C (range 12–49 °C), pH 7.0 (range pH 5.5–9.5) and 0–2 % NaCl (range 0–11 %). (+)-l-Lactate was the main organic acid detected from carbohydrate fermentation with traces of formate, acetate and ethanol. Strain 10CT was catalase-positive, oxidase-negative and reduced nitrate to nitrite under anaerobic conditions. The DNA G+C content was 50.4 mol%. Its closest phylogenetic relatives were Exiguobacterium aestuarii TF-16T and Exiguobacterium marinum TF-80T (16S rRNA gene sequence similarity >99 %). However, strain 10CT differed genotypically from these two Exiguobacterium species as indicated by DNA–DNA relatedness data. Therefore, on the basis of phenotypic, genotypic and phylogenetic characteristics, strain 10CT is considered to represent a novel species of the genus Exiguobacterium, for which the name Exiguobacterium profundum sp. nov. is proposed. The type strain is 10CT (=CCUG 50949T=DSM 17289T).", }
