Summary
Rhodopseudomonas palustris metabolizes p-hydroxybenzoate aerobically via a series of specific reactions which are partly described. The pathway similar to that described for aerobic pseudomonads. The requisite enzymes are absent in extracts of cells grown anaerobically under photosynthetic conditions with p-hydroxybenzoate, benzoate and malate, or aerobically with benzoate or malate. An intermediate of the reaction sequence presumably induces in a retrograde fashion.

Dedicated to Prof. C. B. van Niel on the occasion of his 70th birthday. I wish especially to acknowledge a debt to Prof. C. B. van Niel, who offered an assistant so much encouragement and suggested this and so many other problems in his summer Microbiology Course.
The early portion of this work was done in collaboration with Dr. E. R. Leadbetter in the laboratory of R. Y. Stanier at Berkeley. Mrs. C. Feist generously provided a sample of α-hydroxymuconic semialdehyde. This investigation was supported by the U.S. Public Health Service, Grant HD-02448.
