Claim:
1. A method for converting lignocellulosic biomass material to a carboxylic acid comprising: pretreating lignocellulosic biomass material, wherein the pretreatment is selected from the group consisting of: exposing the lignocellulosic biomass material to a steam treatment, mechanical comminution and a subsequent treatment of the lignocellulosic biomass material with sulfurous acid or its anhydride under heat and pressure with a sudden release of pressure, milling the lignocellulosic biomass material, exposing the lignocellulosic biomass material to cellulose and hemicellulose degrading enzymes, and contacting the lignocellulosic biomass material with a microbial culture for a period of time at an initial temperature and an initial pH, thereby producing an amount of a carboxylic acid, wherein the microbial culture comprises
