Spectral and photochemical properties of the tetra pyrrole pigment corriphyrin synthesized by propionibacterium shermanii

The physico-chemical properties of the tetrapyrrole pigment (corriphyrin) synthesized by P. shermanii were investigated. The spectral properties of the pigment differed from those of natural and synthetic porphyrins and resembled those of dihydroporphyrins. The absorption spectrum in acid media was characterized by an intensive peak at 612 nm, the Soret band at 405 nm and additional band at 380-385 nm. The absorption spectrum in organic solvents (ethanol, chloroform) had 4 bands in the long-wave length area with absorption peaks of 1 > 11 .gtoreq. IV .gtoreq. III. Under these conditions the band occurring, in the short-wave length area (375 nm) was significantly more intensive than that in the Soret band. Fluorescence spectra of corriphyrin was different from those of porphyrins and similar to those of dihydroporphyrine. On the basis of the electrophoretic and chromatographic study of corriphyrin and examination of its behavior during photoreduction and photooxidation it is suggested that corriphyrin is a 7-8 carboxyl tetrapyrrole containing 10 double bonds in the conjugated system and having a methyl group in the .beta.-position of 1 of the pyrrole rings.
