Modeling biochemical systems with constrained Gibbs energy minimization

Research output: Chapter in Book/Report/Conference proceedingChapter or book articleProfessional


Rising costs of fossil resources and products based thereupon has launched a large-scale interest in processing green biomass into raw materials for the chemical industry. Environmental awareness and concern for the global community spur researchers towards seeking thermally efficient and minimally wasteful processes. Current and future biorefinery concepts will use microorganisms to convert lignocellulosic feeds into valuable platform chemicals. However, very few natural organisms produce the desired intermediates in suitable amounts for industrial scale production. The biochemical systems in metabolic engineering are rich in different types of chemical species, modestly reactive, and contain many distinct compartments. A novel method based on multicomponent multiphase Gibbs energy minimization with kinetic constraints and pertinent Legendre transforms has been developed to support thermodynamic modeling of biochemical systems.
