“…In the majority of cases previously reported, demetalation of the vanadyl ion (V=02+) in heavy crude petroleums was followed by profile identification of the demetalated porphyrin compounds, with no mention of the demetalated nonporphyrin ligands (5,25). Although fingerprints of several heavy crude petroleums that have not been demetalated were reported through use of a combination of HPLC and UV-vis detectors (6, 10), we believe this to be the first use of element-selective histograms for the characterization of vanadyl compounds found in heavy crude petroleums.…”

“…Because of this biogenic origin, crude oils from different locations will contain porphyrin isomers in varying proportions. This makes it possible, at least in theory, to differentiate crude oils on the basis of their porphyrin content (Aizenshtat & Sundaraman, 1989;Gratzfeld-Husgen, 1989;Hajibrahim, 1981;Xu & Lesage, 1992).…”

Porphyrins are the molecules which are at the heart of most biochemical reactions involved in bioremediation. This review paper discusses the chemical structures, the biosynthetic pathways and the occurrence of porphyrins in the environment. The parallel between the mammalian and bacterial cytochrome P-450 enzyme systems and the similarity of the reactions at the molecular level is brought to the attention of the reader. Experiments where porphyrins and corrinoids are used as catalysts in the absence of the enzymes or the bacterial cells are opening the field of biochemical remediation, somewhere midway between biological and abiotic reactions. La présence et le rôle des porphyrines dans l'environnement: implications possibles pour la biorestaurationRésumé Les porphyrines sont les molécules qui se retrouvent au coeur de la plupart des réactions biochimiques impliquées dans la biorestauration. Cet article passe en revue les structures chimiques, les chaînes de biosynthèse et la présence des porphyrines dans l'environnement. On dresse un parallèle entre les systèmes enzymatiques cytochromes P-450 d'origine bactérienne et mammifère et la similitude de leurs réactions au niveau moléculaire est soulignée. Des essais où les porphyrines et les corrinoïdes sont utilisées comme catalyseurs en l'absence d'enzymes ou de cellules bactériennes ouvrent la voie à la restauration biochimique, quelque part entre les réactions biologiques et abiotiques.
