Laccase TEA experimental data

Author(s): Elmin Rahic, Nicholas Cassady, Zhiyou Wen, Kurt Rosentrater
Abstract:

Laccase fermentation was conducted by cultivating white-rot fungi (Pleurotus ostreatus) on prairie biomass (growth phase), followed by the induction of laccase using bio-oil aqueous phase (induction phase). This fermentation process was modeled for techno-economic analysis based on experimental data. The experimental data consisted of two parts: 1) optimizing nitrogen concentration for the growth phase, and 2) modeling laccase production and induction phase time using response surface methodology by varying substrate bed depth, substrate to inoculum ratio, and growth phase length.
