Coproporphyrin excretion by Azorhizobium caulinodans under micro-aerobic conditions.

Antonie van Leeuwenhoek - 1 Nov 1998

Pronk A F, Stigter J, Stouthamer A H, de Bruijn F J, Boogerd F C

Abstract excerpt

Azorhizobium caulinodans ORS571 was found to excrete moderate amounts of a fluorescent pigment into the culture medium in response to dissolved oxygen tensions below 1.0 kPa. The pigment was identified as coproporphyrin, on the basis of its optical and fluorescence spectra. FixLJ and fixK mutant derivatives of ORS571 were found to excrete 25-fold higher amounts of coproporphyrin under micro-aerobic conditions...
