RESUMO

Production of a 23,000-Mr major outer membrane protein of Paracoccus denitrificans ATCC 13543 was dependent upon the addition of iron to a succinate-salts medium. The 23,000-Mr protein was not produced in an iron-deficient medium, but production of five outer membrane proteins in the 85,000- to 72,000-Mr range and of catechol were induced. The 23,000-Mr protein was not produced in a complex medium even when ferric citrate was added to the medium. Production of the protein was influenced by the carbon source and was decreased by peptone.
