    • 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.
    • 本发明涉及提高使用木素纤维素生物质作为营养源的微生物过程产量的方法。 所述方法包括用包含酚氧化酶的酶组合物调理包含木质纤维素生物质的组合物。 经调理的组合物可以在一个过程中支持更高的微生物生长速率。 在一个实施方案中,漆酶组合物用于调节源自非木本植物如玉米和甘蔗的木质纤维素生物质。 本发明还包括培养对木质纤维素生物质中抑制性化合物敏感的微生物的方法。 本发明还提供了通过在调理的木质纤维素生物质中培养生产微生物来制备产品的方法。
