Abstract: 

Che.la.ti.vo'rans. N.L. neut. n. chelatum a chelate; L. pres. part. vorans devouring; N.L. masc. n. Chelativorans a bacterium digesting metal chelates.

Proteobacteria / Alphaproteobacteria / Rhizobiales / Phyllobacteriaceae / Chelativorans

Cells of the species of the genus Chelativorans stain Gram-negative and are asporogenous, nonpleomorphic, rod shaped, and often found as pairs of cells. Nonmotile. Multiplication by binary fission is observed. Some species form small white colonies (0.1–0.3 mm in diameter) on EDTA/mineral salt agar incubated for 7 days at 30°C. Oxidase- and catalase-positive. Reduction of nitrate to nitrite and nitrogen fixation are negative. Meso- and neutrophilic; optimal pH and temperature for growth are 6.5–7.5 and 25–35°C, respectively. Strictly aerobic with respiratory metabolism. Do not utilize methanol and methylated amines as the carbon, nitrogen, and energy sources. Incapable of autotrophic or methylotrophic growth. The major cellular fatty acids are summed feature 7 (consisting of C_18:1 ω7c, C_18:1 ω9t, and/or C_18:1 ω12t) and C_19:0 cyclo ω8c. Hydroxy fatty acids such as C_12:0 3-OH, C_13:0 3-OH, and C_15:0 iso 3-OH are absent. The major ubiquinone is Q-10. The predominant polar lipids are PC, PG, PE, PDE, PME, and DP. The major polyamine is sym-homospermidine, and small amounts of spermidine and putrescine are detected.

DNA G + C content (mol%): 60.8–64.3.

Type species: Chelativorans multitrophicus Doronina et al. 2010^VP.
