Abstract

This invention provides novel strains of microorganisms (e.g., Pseudomonas putida Biotype A) which are capable of converting substrates such as toluene or catechol to muconic acid quantitatively by the ortho (catechol 1,2-oxygenase) pathway. Muconate lactonizing enzyme is not induced in the microorganism, thereby permitting the muconic acid to be produced and accumulated in a quantity greater than one gram of muconic acid per liter of bioconversion medium.
