“…Considering the high production and demand for both paper and cellulosic ethanol, a large amount of lignin is annually produced. Current applications of lignin are limited to low‐value products such as dispersing agent, emulsion stabilizer, rheology control materials, and as a low cost fuel to produce energy …”

Microfibers of kraft lignin blended with poly(ethylene oxide) (PEO) were produced by electrospinning of the solution of lignin and high molecular weight poly(ethylene oxide) (PEO) in alkaline water. Interactions between lignin and PEO in alkaline aqueous solutions create association complexes, which increases the viscosity of the solution. The effect of polymer concentration, PEO molecular weight, and storage time of solution before spinning on the morphology of the fibers was studied. It showed that after one day the viscosity dropped and fiber diameter decreased. Results from the solutions in alkaline water and N,N-dimethylformamide (DMF) with different polymer concentrations were compared. The 7 wt % of (Lignin/PEO: 95/5 wt/wt) in alkaline aqueous solution was successfully spun and the ratio of PEO in lignin/PEO mixture could be further reduced. In comparison, higher concentrations were needed to prepare a spinning solution in DMF and fiber diameters were in a much smaller range. The final target of spinning lignin is to produce carbonized fibers. Fibers spun from aqueous solutions had lower PEO content, which is a big advantage for the carbonization process as it reduces the challenges regarding melting of the fibers or void creation during carbonization. Furthermore, the larger diameter of these fibers inhibits disintegration of the carbonized fibers, which happens due to the mass loss during the process.

“…The components of lignocellulose (cellulose, hemicellulose, and lignin) have strong chemical bonds and are diffi cult to separate. Mechanical pretreatment and enzymatic treatments are necessary for the breakdown of lignocellulose (Zhao and Shengdi 2013 ). After the breakdown, the resulting carbohydrates are fermented into bioethanol.…”

“…It has far-reaching research signi cance and application value for the development of a sustainable energy strategy (Adewuyi 2020;Thatoi et al 2016;Zhao et al 2017). Due to competition with food supply in the rst generation of bioethanol production, lignocellulose, a non-starch material, has become an important raw material for bioethanol production (Alonso et al 2019;Balat 2011;Jing et al 2013;Pirzadah et al 2014;Winarni et al 2020). The hydrophobic character of lignocellulose hinders the accessibility of enzymes to cellulose, which is a major obstacle restricting enzymatic hydrolysis (Ferreira et al 2013;Rahikainen et al 2011).…”

Surfactants, especially non-ionic surfactants, play an important role in the preparation of nanocarriers and can also promote the enzymatic hydrolysis of lignocellulose. A broad overview of the current status of surfactants on the immobilization of cellulase is provided in this review. In addition, the restricting factors in cellulase immobilization in the complex multiphase hydrolysis system are discussed, including the carrier structure characteristics, solid-solid contact obstacles, external diffusion resistance, limited recycling frequency, and invalid combination of enzyme active centers. Furthermore, promising prospects of cellulase-oriented immobilization are proposed, including the hydrophilic-hydrophobic interaction of surfactants and cellulase in the oil-water reaction system, the reversed micelle system of surfactants, and the possible oriented immobilization mechanism.
