Biodiversity of Rhizospheric Soil Bacteria and Arbuscular Mycorrhizal (AM) Fungi in Some of The Wild Medicinal Legumes of Barak Valley

Present investigation was aimed to isolate and study the rhizobacteria and AM fungi from rhizosphere of wild legumes: Mimosa pudica (sensitive plant), Crotolaria pallida (Sunhemp), Cassia tora (Sickle pod) and Desmodium . The molecular characterization of four bacterial isolates were done. Four bacterial species - Bacillus megaterium, Bacillus aerophilus, Microbacterium laevaniformans and - Staphylococcus xylosus were isolated from strains M1, RT, D5 and D7 respectively. Also, the distribution of AM fungi population was studied from rhizosphere soils of these legumes. Among the AM fungi, Glomus species was dominant and bacterial genus - Bacillus was found to be dominant. Maximum number of VAM infection was found in the rhizosphere soil of Mimosa pudica of Srikona.
