description: DESCRIPTION OF BLAUTIA ARGI SP. NOV.   
 Blautia argi [ar′ gi. L. masc. n. Argus -i (from Gr. n. Argos), of or pertaining to Argus, in Homer’ s Odyssey the old faithful dog of Ulysses, referring to the isolation of the type strain from a faecal sample of a mature dog].   
 Gram-positive, obligately anaerobic, non-spore forming and non-motile. Cells in colonies formed on RCM with 5 % sheep blood are coccoid or oval-shaped and 0.7–1.0×1.5– 2.6 µm in size. Growth occurs from 20 to 40 Ǫ C, with an optimum of 37 Ǫ C, and from pH 6 to 8, with an optimum of pH 7. The species tolerates up to 3.0 % (w/v) NaCl (optimum, 1.0 %). In the Rapid 32A test the species is positive for arginine dihydrolase, a - galactosidas e, b - galactosidase, a - glucosidase, b - glucosidase and a - arabinosidase, and negative for urease, b- galactosidase-6-phosphate, b- glucuronidase, N -acetyl - b - glucosaminidase, mannose fermentation, raffinose fermentation, glutamic acid decarboxylase, a - fucosidase, reduction of nitrates, indole production, alkaline phosphate, arginine arylamidase, proline arylamidase, leucyl glycine arylamidase, phenylalanine arylamidase, leucine arylamidase, pyroglutamic acid arylamidase, tyrosine arylamidase, alanine arylamidase, glycine arylamidase, histidine, arylamidase, glutamyl glutamic acid arylamidase and serine arylamidase. In the API ZYM test, the species is positive for a- galactosidase, b- galactosidase, a- glucosidase and b- glucosidase activity, but negative for alkaline phosphatase, esterase (C4), esterase lipase (C8), lipase (C14), leucine arylamidase, valine arylamidase, cystine arylamidase, trypsin, a- chymotrypsin, acid phosphatase, naphthol-AS-b-phosphohydrolase, b- glucuronidase, N -acetyl-b- glucosaminidase, a- mannosidase and a- fucosidase activity. Acid is produced from L- arabinose, galactose, glucose, fructose, methyl a- D- glucoside, amygdalin, arbutin, aesculin, salicin, cellobiose, maltose, lactose, melibiose, sucrose, gentiobiose but not glycerol, erythritol, D- arabinose, L- arabinose, D-ribose, D- xylose, adonitol, methyl b- D- xylopyranside, sorbose, rhanmose, dulcitol, inositol, mannitol, sorbitol, methyl a, D- mannopyranside, N -acethyl-glucosamine, trehalose, inulin, melezitose, starch, glycogen, xylitol, D- turanose, D-lyxose, D- tagatose, D- fucose, D- arabitol, L- arabitol, gluconate, 2-keto-gluconate and 5-keto-gluconate by API 50 CH test strips.   
 The diagnostic diamino acid of the peptidoglycan is m - DAP. The major fatty acids are C 14: 0, C 16: 0 and C 18: 1 cis 9. DPG and PG are the major polar lipids, with PL, AL and GL comprising the minor polar lipids. The end products of glucose metabolism are lactic and acetic acids, with trace amounts of formic acid present. The G +C content is 44.2 mol% and the type strain yielded a 77.1 % ANI value and 24.5 % GGD value with B. hansenii KCTC 5951 T.   
 The type strain, N6H1-15 T (= KCTC 15426 = JCM 31394), was isolated from dog faeces. The GenBank/ EMBL / DDBJ accession number for the 16S rRNA gene sequence is KX025138 for N6H1-15 T and MG 493231 for YH1_16.
