DESCRIPTION OF CORTICICOCCUS POPULI SP. NOV.

Corticicoccus populi (po′ pu.li. L. fem. gen. n. populi of the poplar tree).

The description is as given for the genus with the following additions. Colonies are approximately 1–2 mm in diameter after growth for 48 h at 30 Ǫ C on TSA (pH 7). Coccoid cells, about 1.2–1.5 µm in diameter. Growth occurs between 10 and 37 Ǫ C and pH 6 and pH 10, with optima of 28–30 Ǫ C and pH 7.0–8.0. Growth occurs with 0–4 % (w/v) NaCl, with optimum of 2 %. Negative for b- galactosidase, arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase, urease, tryptophan deaminase and gelatinase activities and production of acetoin, indole and H 2 S. Citrate is not utilized. The following carbon sources are utilized at 28 Ǫ C (Biolog GP2): dextrin, N -acetyl-D- glucosamine, D- fructose, a- D- glucose, maltotriose, D- mannitol, D- mannose, b- methyl D- galactoside, a- methyl D- glucoside, D- psicose, salicin, trehalose, a- hydroxybutyric acid, a- ketoglutaric acid, D- lactic acid methyl ester, L- glutamic acid, glycyl L- glutamic acid, glycerol, adenosine 2’-deoxyadenosine, D- galactose, turanose, L- malic acid, methyl pyruvate, succinic acid, 2,3- butanediol and thymidine. Acid is produced from D- glucose, D- fructose, aesculin ferric citrate. eakly positive results for acid production from D- melezitose, D- turanose and D- lyxose. Variable reactions are observed for acid production from trehalose, sucrose and salicin (API 50CHB/E, negative for the type strain). ositive for alkaline phosphatase, esterase lipase (C8), leucine arylamidase and b - glucosidase activities. Variable reactions are observed for esterase (C4) and valine arylamidase (negative for the type strain) activities.

The type strain is 26D10-3-4 T (= CFCC 12725 T = KCTC 33575 T), isolated from symptomatic bark tissue of a Populus × euramericana canker. The DNA G+C content of the type strain is 38.2 mol%. An additional strain of the species is 9-4-1 .
