Free-living soil bacteria beneficial to plant growth are usually referred to as plant growth promoting rhizobacteria (PGPR), capable of promoting plant growth by colonizing the plant root. Application of PGPR to increase the yield is limited by variability among the results obtained in the laboratory, in greenhouse and field. Rhizobacteria that promote plant growth (PGPR) participate in interactions with plants (rice, wheat, maize, sugarcane, sugar beet, cotton) and significantly increase their vegetative growth and yield. Apart from Azotobacter and Azospirillum, PGPR also include Acetobacter, Azoarcus and several species of Enterobacteriaceae (Klebsiella, Enterobacter, Citrobacter, and Pseudomonas). PGPR represent an alternative to plant growth enhancement chemicals.
