Producing biomass results in the fixing of atmospheric carbon dioxide into organic carbon. Converting this biomass to a useable fermentation feedstock (typically some form of sugar) can be achieved using a variety of different process technologies. These processes for fermentation feedstock production constitute the critical differences among all of the bioethanol technology options. Fermenting the [...]
