General Information: Root-associated nitrogen-fixing bacterium. Herbaspirillum seropedicae is an endophitic nitrogen-fixing beta-Proteobacteria found associated with important crops such as sugarcane, wheat, maize, rice and sorghum. It is non-phytopathogenic and produces interesting biotechnological products such as polybetaalkanoates and cyanophycin. Herbaspirillum seropedicae was isolated from the roots of rice plants, and is member of a group of free-living soil bacteria known to promote plant growth. The yields of rice and sorghum were significantly increased when grown in soil inoculated with Herbaspirillum seropedicae.
