Abstract
Plant rhizosphere is a very complex niche in which soil, plants, and microbe interaction occur, and plant roots harbor an assembly of different beneficial and deleterious microorganisms. The nitrogen-fixing attribute of legumes with rhizobia plays a key role in maintaining soil fertility for legumes and subsequently non-leguminous plants. The identification and characterization of indigenous rhizobium strains is a prerequisite for sustainable crop production. This research was carried out to isolate and characterize morphologically and using biochemical methods the bacteria from the root nodules of groundnut and bean. Thirteen bacteria were isolated from the root of groundnut (38%) and beans (62%). Based on the colony characteristics, cell morphology, and the ability to absorb Congo red dye seven (G1, G1 (2), G2, G2 (2), B2.3 (2), G2 (2), and B2.3 (1)) out of the thirteen tested isolates were suspected to be rhizobia. The result of the study also shows a variation in diversity and the type of bacteria nodulating the root of groundnut and beans. However, further phenotypic and molecular characterization is required to confirm the isolates given that, are rod shape which is a characteristic of rhizobia. This study could an innovative way of improving plant nutrient availability or it could be a starting point of molecular studies.
