Description

Indole-3-acetic acid (IAA) production from L-tryptophan (L-Try) and IAA destruction were examined using Rhizobium meliloti. Nitrate did not affect the rate of L-Try decomposition by this bacterium. IAA was decomposed under non-aseptic condition, but not under aseptic condition irrespective of the presence of this bacterium. It is therefore concluded that a strain of R. meliloti used in this experiment can not decompose IAA.
