Species of bacterium From Wikipedia, the free encyclopedia
Ensifer numidicus is a nitrogen fixing symbiont of Fabaceae.[1] gram-negative, aerobic, non-spore forming, rod-shaped bacterium of the family Rhizobiaceae.[2] First described in 2010;[1] more biovars have since been isolated and described[3] with ORS 1407 considered the representative organism.[4] Most examples have been found in arid and infra-arid regions of Tunisia.[5]

Biovars has been shown to induce nodule formation in a wide variety of symbiosis competent plant species including Medicago Sativa(cultivated alfalfa)[6], Lotus creticus[3], Syrian mesquite(Prosopis farcta),[7] Lens culinaris Medikus ssp(lentils)[3][8] as well as Cicer arietinum(chickpea)[3] and Argyrolobium uniflorum.[1]

This phylogeny is based on a constrained analysis of the 16S ribosomal RNA[1]
16s RNA analysis has found Ensifer numidicus to be closely related to Ensifer medicae and Ensifer garamanticus.[3] Analogous genes between closely related species suggests high levels of horizontal gene transfer between closely related species.[3] Laboratory inoculation has shown Ensifer numidicus engages in indeterminate nodulation with host plants in at least some circumstances.[9]
E. numidicus has been found to grow on yeast-mannitol medium at 28C with an upper limit of 40C.[1] Laboratory cultivated strains have found metabolism of at least 13 substrates including dulcitol, D-lyxose, 1-O-methyl a-D-glucopyranoside, 3-O-methyl-D-glucopyranose, D-gluconate, L-histidine, succinate, fumarate, ethanolamine, DL-b-hydroxybutyrate, L-aspartate, L-alanine and propionate.[1] Sensitivity has been found to salt concentrations greater than 4%.[3] Due to similarities to other Ensifer species, it cannot be described by growth conditions alone and must be differentiated by genetic components.[3]
