description
Cells are Gram-positive, strictly aerobic, non-motile and rod shaped (0.3 – 1.0 µm wide; 1.3 – 2.8 µm long). Colonies grown on R 2 A agar plates for 2 days are smooth, convex, opaque and milky-white to creamy in colour. Positive for catalase and oxidase activities. Growth occurs at 18 – 42 Ǫ C and pH 6.0 – 7.0 with 0 – 6.0 % NaCl (w / v). Does not grow at 15 and 45 Ǫ C. Optimum growth occurs at 30 Ǫ C and pH 6.5 without NaCl (w / v) supplement. In the API 20 NE and ZYM kits, enzyme activity results are positive for alkaline phosphatase, esterase, leucine arylamidase and cystine arylamidase, and negative for nitrate reduction, indole production, glucose acidification, arginine dihydrolase, urease, b- glucosidas, a- galactosidase, b- galactosidase, b- glucuronidase, a- glucosidase, b- glucosidase, N - acetyl-b- glucosaminidase, a- mannosidase, a- fucosidase, trypsin, a- chymotrypsin, acid phosphatase, naphthol-AS-BIphosphohydrolase, valine arylamidase, esterase lipase and lipase. In the API 20 NE and 32 GN kits, positive assimilated compounds are: malate, citrate, phenyl-acetate, propionate, caprate, 3 - hydroxy-butyrate, 4 - hydroxy-benzoate, 5 - ketogluconate, L- histidine, L- rhamnose, N - acetyl-D- glucosamine, sucrose, maltose, suberate, L- alanine, glycogen, 3 - hydroxybenzoate and L- serine, and negatively assimilates: acetate, lactate, malonate, itaconate, D- ribose, inositol, L- proline, 2 - ketogluconate, salicin, melibiose, L- fucose, D- sorbitol, D- mannitol, D- glucose, L- arbinose, D- mannose, maltose, gluconate, caprate and adipate. The quinones are MK- 8 (H 2) and MK- 7 (H 2), and anteiso-C 15: 0, anteiso-C 17: 0, iso-C 16: 0 and iso-C 15: 0 are the major cellular fatty acids. The major polar lipids is phosphatidylglycerol. The peptidoglycan of strain BS 05 T contains the amino acid meso - diaminopimelic acid.
