From sewage and soil isoquinoline-degrading organisms were enriched. Two strains could be isolated which were able to utilize isoquinoline as sole carbon source. The bacteria were tentatively identified as Alcaligenes faecalis and Pseudomonas diminuta with respect to their morphological and physiological characters. When growing on isoquinoline both strains excrete a metabolite into the medium which was identified as 1-oxo-1,2-dihydroisoquinoline. Alcaligenes faecalis was cultivated in continuous culture on 1-oxo-1,2-dihydroisoquinoline to improve growth on isoquinoline and degradative activity.

UI MeSH Term Description Entries
D007546 Isoquinolines A group of compounds with the heterocyclic ring structure of benzo(c)pyridine. The ring structure is characteristic of the group of opium alkaloids such as papaverine. (From Stedman, 25th ed)
