Effects of Oxygen Limitation on the Biosynthesis of Photo Pigments in the Red Microalgae Galdieria sulphuraria Strain 074G

As a consequence of the inhibition of one of the steps in the biosynthesis of the photopigments chlorophyll and phycobilin, the red microalga Galdieria partita excretes coproporphyrinogen III in the medium when growing on glucose. No coproporphyrinogen III was found when the closely related red micr...

description As a consequence of the inhibition of one of the steps in the biosynthesis of the photopigments chlorophyll and phycobilin, the red microalga Galdieria partita excretes coproporphyrinogen III in the medium when growing on glucose. No coproporphyrinogen III was found when the closely related red microalgae G. sulphuraria strain 074G was grown on glucose and excessive amounts of oxygen. When under the same conditions oxygen was limiting, coproporphyrinogen III was present in the medium. We conclude that not glucose but the amount of oxygen in the medium results in the accumulation of coproporphyrinogen III. This is explained by the inactivition of the oxygen-dependent coproporphyrinogen III oxidase that converts coproporhyrinogen III to protoporphyrinogen IX, one of the intermediate steps in the biosynthesis of chlorophyl and phycobilin.
