Phenotypic characteristics and composition of rhizobia associated with woody legumes growing in diverse Kenyan conditions

Over 480 rhizobia were isolated from root nodules of woody legume and herbaceous trap host species grown in soils collected from 12 different Kenyan sites. The isolates were differentiated by growth and morphological characteristics, intrinsic antibiotic resistance (IAR) and salt (NaCl) tolerance levels (STL) when grown on yeast mannitol mineral salts agar and broth media.
