| Abstract: | Summary High perfomance liquid chromatography (HPLC) of the products of [5-3H] tryptophan metabolism byFrankia sp. Avc I1 indicates that small amounts of [3H] indole-3-acetic acid (IAA) are excreted into the growth medium.Frankia has a limited capacity for the catabolism of [2-14C]IAA and the product that accumulates is different from that detected inRhizobium japonicum cultures following inoculation with [2-14C]IAA. The data imply that the rate of turnover of IAA is much more rapid inRhizobium thanFrankia and that the two organisms employ different routes for the catabolism of IAA. |
