Title: Methods of processing aromatic compounds

Abstract

A method of processing a solution comprising aromatic compounds. The method includes culturing a first microorganism in the solution for a time sufficient to reduce an amount of an aromatic compound and thereby generate a processed solution. The culturing may remove an aromatic compound deleterious to growth of a second microorganism without substantially reducing fermentable sugars, thereby permitting enhanced growth of the second microorganism in the processed solution. The culturing may additionally or alternatively convert an aromatic compound into a commodity chemical. The methods of the present invention are advantageous for processing lignocellulosic biomass for upgrading to biofuel or for generating commodity chemicals therefrom.
