Abstract:
Second-generation bioethanol is a sustainable energy source that can be produced from different renewable materials. However, there is a challenge we must overcome to significantly enhance bioethanol production: the hydrolysis of lignocellulosic biomass to fermentable sugars. Synergistic enzymes, such as endoglucanases, β-glucosidases, cellobiohydrolases, and, more recently, lytic polysaccharide monooxygenases and cellobiose dehydrogenases have been used with great success to hydrolyze pretreated biomass. Further advances in the field of second-generation bioethanol production will likely depend on an increased understanding of the interactions between enzymes and lignocellulosic substrates, the development of enzyme engineering, and the optimization of enzyme mixtures to enhance cellulose hydrolysis.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Fermentation
Fermentation is a type of metabolic process that occurs in the absence of oxygen, where organic molecules such as glucose are broken down to produce energy. During this process, the...
