In the future, three crucial factors will determine the likelihood of success for the direct microbial conversion of biomass to advanced biofuels: the properties of the lignocellulosic biomass feedstock, the pretreatment process, and the specific microbial processing strategy selected. Each step accounts for a substantial portion of total process cost. Here, we extend the technical umbrella for advanced biofuels to technologies including and beyond the scope of the book, such as (1) upstream-new concepts for feedstocks, (2) midstream-specialized pretreatments and cotreatments, and (3) downstream-processing of biomass sugars. The aim of this chapter is not to provide a review of specialized fields, but to highlight new concepts and approaches related to biomass processing. We emphasize the important new trends in "green production" of feedstocks, technologies for "green pretreatment" of biomass, and propose new concepts for tailored chemoprocessing-databases/libraries customized for specific microorganisms applied to specific processes.
