DESCRIPTION OF LYSINIMONAS YZUI SP. NOV.

Lysinimonas yzui (y.zu ′ i. N.L. gen. n. yzui pertaining to YZU, Yangzhou University, where the taxonomic studies on the type strain were performed).

Cells are Gram-stain-negative, non-spore-forming, aerobic and non-motile rods. Colonies are yellow, round and convex aħer 4 days of growth at 28 °C on R2A agar. Cells are usually 0.5–0.7 µm wide and 1.0– 1.1 µm long. Growth occurs at 10–37 °C (optimum 30 °C) and at pH 6–9 (optimum pH 7.5) and in the presence of 0–5% (w/v) NaCl. Growth does not occur under anaerobic conditions. Oxidase-negative, urease-negative and catalase-positive. Negative for hydrolysis of carboxymethyl cellulose, gelatin, DNA, casein, starch and tyrosine and positive for hydrolysis of Tween 80. Does not assimilate erythritol, D-arabinose, D-ribose, L-xylose, D-ardonitol, methyl β-D-xylopyranoside, L-sorbose, D-sorbitol, raffinose, starch, D-lyxose, D-tagatose, D-fucose, L-fucose, potassium gluconate or potassium 5-ketogluconate (API 50 CH test strips). Positive for the following enzyme activities (API ZYM test strips): alkaline phosphatase, esterase (C4), esterase lipase (C8), cystine aromatase, acid phosphatase, naphthol-AS-BI-phosphate hydrolase, α-galactosidase, β-galactosidase, α-gluconase and β-gluconase. The major fatty acids are anteiso-C15:0, iso-C15:0, C16:0, iso-C16:0 and anteiso-C17:0.

The type strain, N7XX-4 T (=CGMCC 1.16548 T =DSM 106791 T =JCM 32630 T), was isolated from cattail root grown on mine tailings from Phoenix Mountain, Tongling city , Anhui Province (PR China). The G+C content of the DNA of the type strain is 67.0 mol%(by HPLC) and 69 mol% (by genome-based analysis) .
