Lonsdalea Brady et al. 2012
General information
Description and emendation
Cells are Gram-negative short rods (0.5-1.0 × 1.0-2.0 µm) occurring singly, in pairs or in groups. Motile by peritrichous flagella. Facultatively anaerobic, oxidase negative but catalase positive. Optimum temperature for growth is 28-30°C. Colonies are white to cream on tryptone soya agar, round, convex and smooth with entire margins. Negative in tests for β-galactosidase, arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase and tryptophan deaminase activities. Citrate is utilized but no production of H2S, urease, indole or gelatinase. Nitrates are not reduced to nitrites. Acid is produced from N-acetylglucosamine, arbutin, D-fructose, D-glucose, D-mannose, methyl α-D-glucopyranoside, D-ribose, salicin, sucrose and turanose. Major fatty acids are C14:0, C16:0, C18:1 ω7c, C17:0 cyclo and summed features 2 (iso-C16:1 and/or C14:0 3-OH) and 3 (C16:1 ω7c and/or iso-C15:0 2-OH). Members of the genus may cause disease on oak trees including drippy nut disease and bark canker and may be associated with Acute Oak Decline. The DNA G+C contents range from 54.5 to 55.1 mol%.
