“…Various mechanisms of action have been described to explain these effects that will be described further in this manuscript. These emulsifiers and proteins contain simultaneously polar and non-polar regions, which impart them with surface-active properties [30] that can stabilize the two-phase system. Improving enzyme activity through the application of amphiphiles not only reduces the operating costs of ethanol production from biomass by reducing the amount of enzyme required, but also reduces fermentation time, thereby lowering capital costs.…”

Abstract:One of the concerns for economical production of ethanol from biomass is the large volume and high cost of the cellulolytic enzymes used to convert biomass into fermentable sugars. The presence of acetyl groups in hemicellulose and lignin in plant cell walls reduces accessibility of biomass to the enzymes and makes conversion a slow process. In addition to low enzyme accessibility, a rapid deactivation of cellulases during biomass hydrolysis can be another factor contributing to the low sugar recovery. As of now, the economical reduction in lignin content of the biomass is considered a bottleneck, and raises issues for several reasons. The presence of lignin in biomass reduces the swelling of cellulose fibrils and accessibility of enzyme to carbohydrate polymers. It also causes an irreversible adsorption of the cellulolytic enzymes that prevents effective enzyme activity and recycling. Amphiphiles, such as surfactants and proteins have been found to improve enzyme activity by several mechanisms of action that are not yet fully understood. Reduction in irreversible adsorption of enzyme to non-specific sites, reduction in viscosity of liquid and surface tension and consequently reduced contact of enzyme with air-liquid interface, and modifications in biomass chemical structure are some of the benefits derived from surface active molecules. Application of some of these amphiphiles could potentially reduce the capital and operating costs of bioethanol production by reducing fermentation time and the amount of enzyme used for saccharification of biomass. In this review article, the benefit of applying amphiphiles at various stages of ethanol production (i.e., OPEN ACCESSAppl. Sci. 2013, 3 397 pretreatment, hydrolysis and hydrolysis-fermentation) is reviewed and the proposed mechanisms of actions are described.

“…Because these parameters were remarkably varied with pH of the solution, it was suggested that the variation in the dissociation state of the amino-and carboxyl-groups in the amphoteric macromolecules with pH and the resulted variation in the electric charge of the macromolecules is closely related to the behavior of the adsorption onto the bubble surface. The influence of pH both on protein adsorption behavior and on the state of the adsorbed protein molecules on bubble surfaces is important not only for foam separation technique but also for emulsification [12,13], foam stability [14][15][16][17][18], food processing [19,20], and so on.…”

“…The mechanism of action of low molecular weight surfactants was linked in [4] to the process of competitive adsorption by the surface activity values of the formed complexes. A significant factor in this arrangement is the chemical nature of the egg white and LMS and the type of the oil-water and water-to-air interfaces [5]. Competitive adsorption in multicomponent food systems is complicated by the presence of several phases, including fat crystals [6].…”
