Azospirillum lipoferum, is a free living, gram positive, plant-growth-promoting a-proteobacteria, capable of affecting the growth and yield of numerous plant species, many of agronomic and ecological significance. The leading theory concerning its growth promotion capacity lies in its ability to produce various phytohormones that improve root growth, adsorption of water and minerals that eventually yield larger, and in many cases more productive plants (Dobbelaere et al. 2001)The organism was first described by Martinus Beijerinck who named it Spirillum lipoferum , in 1925. Later, the classification was revised by Tarrand et al. who renamed it Azospirillum lipoferum which means "small, fat bearing, spiral".
