Isolation and Characterization of Rhizobium Meliloti Isolated from Rhizosphere Soil and Roots of Fenugreek (Trigonella Foenum Graecum Linn) from Different Locations

Mr. Satyadev Prajapati

The nine isolates of Rhizobium meliloti were isolated on CR-YEMA medium from root nodules and rhizosphere soil of fenugreek. Four isolates showed absorption of Congo red and rest five isolates did not absorbed Congo red. All the isolates showed similar cultural characteristic for colony colour and shape except for colony size. Colonies of all isolates were whitish, translucent, sticky nature, rounded and had a diameter in the range of 3.2 to 5.2 mm. All the isolates showed positive reaction for biochemical test viz., catalase test, potassium hydroxide and starch hydrolysis test and showed negative reaction for Gram’s staining.
