''Ensifer fredii'' is a nitrogen fixing bacteria of the genus Sinorhizobium. It is a fast-growing root nodule bacteria. ''Sinorhizobium fredii'' exhibit a broad host-range and are able to nodulate both determinant hosts such as soy as well as indeterminate hosts including the pigeon pea. Because of their ease of host infection there is interest in their genetics and the symbiotic role in host infection and nodule formation.
