acinetobacter nectaris acinetobacter nectaris acinetobacter nectaris is a gram-negative, oxidase-negative, catalase-positive, strictly aerobic nonmotile bacterium from the genus acinetobacter isolated from floral nectar pollinated by mediterranean insects in the doñana national park in the huelva province in spain. bacterial communities, including microbes identified as a. nectaris are closely associated with plant communities; other strains of bacteria (gluconoacetobacter, erwinia and rhizobium) have been found in environments that mother bees visit. this bacterium was first characterized in 2013. acinetobacter nectaris scientific classification domain: bacteria phylum: pseudomonadota class: gammaproteobacteria order: pseudomonadales family: moraxellaceae genus: acinetobacter species: a. nectaris binomial name acinetobacter nectarisálvarez-pérez et al., 2013 type strain cect 8127, lmg 26958, sap 763.2
