Hydrolytic enzyme production by Rhizobium.

E Martinez-Molina¹, V M Morales, D H Hubbell.

Abstract

Cellulase and hemicellulase activity was detected in temperate (infective and noninfective) and tropical strains (infective) of Rhizobium. Hydrolytic enzymes were initially detected by a cup-plate assay. The presence of cellulase and hemicellulase was confirmed by viscometric assay. Implications of the presence of these enzymes in Rhizobium are discussed.
