SSF in relation to other process options. The arrows show the approach of SSF to other process options as a result of process changes. (Abbreviations: SSF = simultaneous saccharification and fermentation; SHF = separate hydrolysis and fermentation; CBP = consolidated bioprocessing, i.e. a process in which the enzymes are produced by the fermenting organism; SSCF = simultaneous saccharification and co-fermentation; SoSF = solid state fermentation.)
