Development of a lactic acid production process using lignocellulosic biomass as feedstock

Research output: Thesisinternal PhD, WU

Abstract

The availability of crude oil is finite. Therefore, an alternative feedstock has to be found for the production of fuels and plastics. Lignocellulose is such an alternative feedstock. It is present in large quantities in agricultural waste material such as sugarcane bagasse.

In this PhD thesis, lignocellulose is chemically and enzymatically pretreated to depolymerise sugars present in this structure. The released sugar monomers are fermented by micro-organisms to lactic acid, which is a precursor for the bioplastic PLA. In this thesis, it is shown that it is possible to produce lactic acid from lignocellulosic biomass with high yields and high productivities.
