Abstract
AnArthrobacter sp. growing on 4-Chlorobenzoic acid as its sole source of carbon excretes 4-hydroxybenzoic acid and protocatechuic acid into the culture medium. Protocatechuic acid is further attacked by “meta”-cleavage. During growth of theArthrobacter sp. on benzoic acid cis-cis muconic acid can be isolated from the medium, suggesting the involvement of the “ortho”-cleavage pathway. The enzymes both for the “meta”- and the “ortho”-cleavage pathway are inducible.
Zusammenfassung
EineArthrobacter-Species, die 4-Chlorobenzoesäure als einzige Kohlenstoffquelle verwerten kann, gibt beim Wachstum auf dieser Verbindung 4-Hydroxybenzoesäure und Protocatechusäure ins Medium ab. Der weiter Abbau des aromatischen Ringes erfolgt durch “meta”-Spaltung. Beim Wachstum derArthrobacter-Species auf Benzoesäure trit im Medium cis,cis-Muconsäure auf. In diesem Fallewird also der “ortho”-Weg eingeschlagen. Die Enzyme für beide Abbauwege sind induzierbar.
