•R. tropici mutants that produced high levels of EPS compared to the wild-type.•RP-HPLC analysis showed that EPS was a heteropolysaccharide with six different sugars.•Rhizobial EPS showed a typical non-Newtonian and pseudoplastic.•The MUTZC3, JAB1 and JAB6 can be suggested as best strains for the in...
