Production of bioethanol from LB is carried out by the following three steps:
1. Pretreatment
2. Hydrolysis
3. Fermentation
However, in some cases, steps (2) and (3) can be combined to carry out SSF
(simultaneous saccharification) or SSCF (simultaneous saccharification and
co-fermentation). Figure 5.2 is representing the steps involved in bioethanol production from LB. The non-carbohydrate components (lignin) go through the valorization step to make other value-added products.
