“…75 Contrary to amyloid fibrils, silk β-sheets composed of Gly and Ala did not express significant cytotoxicity, most likely because of a lack of electrical charge. Nano-assembly of silk β-sheets produced microfibrils after incubation for 72 h (Figure 5a), and formation of the nano-assembly was faster than that of Aβ (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28), Aβ (28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42) and full-length Aβ(1-42) because of the greater hydrophobicity of the silk β-sheet. 76,77 The control of silk β-sheet formation is key the assembly needed to create artificial tough polymeric materials; however, this control has not yet been established because β-sheets assemble via hydrophobic interactions too quickly to regulate in solution.…”

Poly(amino acids) and polypeptides have the potential to contribute significantly to a biomass-based and sustainable society, due to their biomass origin, functionality, and unique physical properties. To realize amino acid-based polymers as eco-friendly alternatives for petroleum materials, the synthesis of poly(amino acid)s/polypeptides through an environmentally friendly process is needed. In this focus review, the author summarizes the recent progress of chemo-enzymatic polymerization, which is a green and atom-economical reaction that provides new insight into the design of materials from polypeptides. Additionally, polypeptides can be designed to serve as functional and structural materials. The use of peptides as carriers of nucleic acids for delivery into target cells and organelles is one important application of such functional materials. Studies on polypeptides as structural materials are also reviewed. POLY(AMINO ACID) AS AN ECO-FRIENDLY MATERIALEco-friendly polymeric materials have been designed and processed primarily from bio-based polyesters such as poly(hydroxyalkanoate) 1 and poly(lactic acid), 2,3 due to their plasticity, excellent workability, and biomass origin. 4-12 Poly(hydroxyalkanoate) has several advantages such as the ability to be directly synthesized from various types of biomass, including lignin and carbon dioxide, 13-17 and excellent biodegradability. 18,19 However, because of a lack of toughness, this biopolyester has limited use and application. Development of an engineered biopolymer such as a biomass-derived polyamide is an emerging interest in the field of sustainable chemistry and materials engineering. Biopolyamides (for example, nylon 4) have been investigated as candidates for biomass-based engineering plastics, but their narrow processing window for thermo-forming currently prevents them from being considered for practical purposes. 20 Natural high-performance materials, including spider silk and mussel-derived adhesive (Figure 1), are mainly composed of poly(amino acid)s and a small amount of short peptides, suggesting that poly(amino acid)s could serve as an alternative to the petroleum-derived polymers in support of a sustainable society. Although spider dragline silk is a benchmark in terms of tough materials, scientific and technological advances still cannot produce an artificial dragline silk. To create and develop biomass-based tough polymers like this silk, the synthesis and design of materials from poly(amino acid)s is being investigated.A poly(amino acid) is a polymer composed of amino acids as monomeric units. Structural and functional proteins, polypeptides, peptides and polymers derived from amino acids, that is, poly(β-alanine) and ε-poly(lysine), are classified as poly(amino acid)s. The use of poly(amino acid)s as functional materials has been widely studied, resulting in the development of polypeptides that are bioactive and that can have biological applications such as in tissue engineering, regenerative medicine and drug/gene delivery systems.

“…The study of lignin applications can be divided into two different fields: materials and fuels/chemicals. The former include phenolic resins, epoxies, adhesives, polyolefins, carbon fiber, and PHAs . The latter consists of syringol, guaiacol, BTX (benzene, toluene, and xylene), vanillin, lipids, and jet fuel .…”

Utilizing lignin feedstock along with cellulosic ethanol for the production of high‐energy‐density jet fuel offers a significant opportunity to enhance the overall operation efficiency, carbon conversion efficiency, economic viability, and sustainability of biofuel and chemical production. A patented catalytic process to produce lignin‐substructure‐based hydrocarbons in the jet‐fuel range from lignin was developed. Comprehensive techno‐economic analysis of this process was conducted through process simulation in this study. The discounted cash flow rate of return (DCFROR) method was used to evaluate a 2000 dry metric ton/day lignocellulosic ethanol biorefinery with the co‐production of lignin jet fuel. The minimum selling price of lignin jet fuel at a 10% discount rate was estimated to be in the range of $6.35–$1.76/gal depending on the lignin and conversion rate and capacity. With a production capacity of 1.5–16.6 million gallon jet fuel per year, capital costs ranged from $38.0 to $39.4 million. On the whole, the co‐production of jet fuel from lignin improved the overall economic viability of an integrated biorefinery process for corn ethanol production by raising co‐product revenue from jet fuels. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
