| P. agglomerans was first described in 1888 and has been identified under many names including: ''Enterobacter agglomerans, Erwinia herbicola, Bacillus agglomerans, Bacterium herbicola, Pseudomonas herbicola, Agrobacterium gypsophilae, Bacterium typhi flavum, Erwinia lathyr, Corynebacterium beticola, Flavobacterium rhenanum, Pseudomonas trifolii'', ''and Xanthomonas'' trifolii.

| The etymology of its name is ‘Pantoea’, derived from the Greek word ‘pantoios’, which means ‘of all sorts and sources’, reflecting its ubiquitous occurrence; and ‘agglomerans’ meaning ‘forming into a ball’, due to the tendency for P. agglomerans to aggregate into clusters.

| Pantoea agglomerans is a non-spore forming, Gram-negative, rod-shaped, facultative anaerobe bacillus that is motile via peritrichous flagella. It forms yellow pigmented colonies with 5mm concave centers. P. agglomerans grows quickly on agar at 30°C at a rate comparable to E. coli. P. agglomerans is found ubiquitously on plants as both an epiphyte and an endophyte. It forms host associations with a diverse variety of hosts including plants, insects, and humans. P. agglomerans is found abundantly in plants, animals, arthropods, feces, soil, water, dust, air, and in humans. P. agglomerans is as ubiquitous in function and application as it is in occurrence, it produces a wide variety of molecules depending on where it is grown with both positive and negative attributes. It has multiple bioremediation applications as a natural fertilizer and pesticide, replacing harmful chemical alternatives. Other bioremediation applications include natural feed additives for poultry, breaking down herbicides into nontoxic byproducts, and the ability to break down petroleum hydrocarbons.

| P. agglomerans demonstrates a wide array of medical applications as well, producing multiple compounds that are utilized to produce powerful biocontrol agents for humans and plants that function as antibiotics, antifungals, and antivirals. P. agglomerans also produces a unique lipopolysaccharide that acts as a macrophage activator and immunopotentiator which has been utilized in research to suppress cancerous tumors.
