报告摘要：

Although there are many methods to produce biofuels, feed, biofertilizers and over 200 high value-added chemicals from lignocellulosic biomass, the commercialization of lignocellulosic biorefineries is still rare. The challenges are related to the entire feedstock supply chain and sustainability of existing pretreatment and conversion methods. In addition, there is lack of standardization in the pre-treatment and conversion of lignocellulosic biomass into bio-based products. Solid state fermentation (SSF) is one of the biological methods that has recently attracted a lot of attention in the scientific world. SSF is a fermentation process in which microorganisms grow on moist lignocellulosic materials under controlled conditions, without the presence of free water or with a minimal amount of free water. Although many microorganisms can be used in SSF, filamentous fungi are the most commonly used, especially those from Basidiomycota and Ascomycota fungal kingdom sub-divisions.

In this lecture, examples of fungal-based solid-state fermentation of selected lignocellulosic materials (brewer’s spent grain, corn silage, sugar beet pulp, and pumpkin oil pomace) for the production of enzymes (laccase and lipase), biofuels and high-quality protein-enriched feed, will be given. A case study and a techno-economic analysis of the application of Trametes versicolor in biogas production on a pilot scale using corn silage pre-treated with T. versicolor and cow manure as substrates will be presented.
