Abstract
Official abstract text for this publication.
The present invention relates to methods for improving the yield of microbial processes that use lignocellulose biomass as a nutrient source. The methods comprise conditioning a composition comprising lignocellulose biomass with an enzyme composition that comprises a phenol oxidizing enzyme. The conditioned composition can support a higher rate of growth of microorganisms in a process. In one embodiment, a laccase composition is used to condition lignocellulose biomass derived from non-woody plants, such as corn and sugar cane. The invention also encompasses methods for culturing microorganisms that are sensitive to inhibitory compounds in lignocellulose biomass. The invention further provides methods of making a product by culturing the production microorganisms in conditioned lignocellulose biomass.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for culturing a production microorganism that produces a desired product, which is an enzyme, said method comprising: contacting a composition comprising a lignocellulose biomass with a cell-free composition comprising a phenol oxidizing enzyme for a period of time sufficient to condition said composition for microbial growth, and growing said production microorganism in said conditioned composition, wherein said lignocellulose biomass has not b…
