rhi·zo·bi·um

(rī-zō′bē-əm)

n. pl. rhi·zo·bi·a (-bē-ə)

Any of various aerobic bacteria of the genus Rhizobium that form root nodules in leguminous plants, such as clover and beans, where they establish a symbiotic relationship in which the bacteria obtain carbon and energy from the plant while supplying the plant with nitrogen by nitrogen fixation.

[New Latin Rhizobium, genus name : rhizo- + Greek bios, life; see g^wei- in Indo-European roots.]
