Novel methods for the in vivo production of phenol from renewable substrates using a recombinant microorganism (FIG. 1). Additionally, methods for the in vivo production of catechol and cis,cis-muconic acid from renewable substrates using a recombinant microorganism are disclosed. A host cell expresses at least one gene encoding a polypeptide that possesses isochorismate synthase activity, at least one gene encoding a polypeptide that possesses isochorismate pyruvate lyase activity, and at least one gene encoding a polypeptide that possesses salicylic acid decarboxylase activity. In the case of catechol, the host cell must additionally express at least one gene encoding a polypeptide that possesses phenol 2-monooxygenase activity. In the case of cis,cis-muconic acid, the host cell must additionally express at least one gene encoding a polypeptide that possesses phenol 2-monooxygenase activity and at least one gene encoding a polypeptide that possesses catechol-1,2-dioxygenase activity.

Mycobacteriumtuberculosissalicylatesynthase (MbtI), a member of the chorismate‐utilizing enzyme family, catalyses the first committed step in the biosynthesis of the siderophore mycobactin T. This complex secondary metabolite is essential for both virulence and survival of M. tuberculosis, the etiological agent of tuberculosis (TB). It is therefore anticipated that inhibitors of this enzyme may
