“…The number of BEs in the LCC and 13 C-LCC were 2.12 and 11.84 per 100 Ar. These values correspond to the values previously reported for the LCC linkages of A. donax L. (You et al 2015). The difference of BE2 in the LCC and 13 C-LCC was due to the 13 C-labeling, which indicated that part of the lignin and xylan in wheat straw were connected by benzyl ether bonds.…”

“…Compared with LCCs in Arundo donax L., the molecular weights of wheat straw LCCs were higher. This result was attributed to the different species and different mobile phase used with GPC (You et al 2015). The Mw of the LCC-13 C was slightly higher than that of the LCC, indicating that there were more saccharides connected to the lignin in the LCC-13 C than in the LCC sample (Yang et al 2013a); this result corresponded to the results obtained from the carbohydrate analysis (discussed below).…”

“…There was no signal detected at δC/δH 75/6.1 ppm for a benzyl ester (α-ester) (You et al 2015). Signals from Cγ in the γ-ester were found in the range of δC/δH 65 to 62/4.0 to 4.5 ppm.…”

“…The strong absorption at 1046 cm -1 was from stretching vibrations of C-O and C-C, which indicated the presence of xylans (Sun et al 2005). Additionally, signals from C=O stretching were observed at 1731 cm -1 , which was attributed to esterified phenolic groups and acetyls connected to the hemicelluloses (You et al 2015). The weak signal at 1630 cm -1 was assigned to the uronic acid group from hemicelluloses.…”

“…The rigid lignin blocks can form lignin-protein complexes with membrane bound proteins in animal cells, enabling cells to grow [14]. Furthermore, the flexible polysaccharide blocks containing 2-5% galactan have the ability to recognize hepatocytes due to the presence of asialoglycoprotein receptors (ASGPR) on which galactose acts as a specific adhesive ligand on the hepatocytes [15][16][17][18][19] (Figure 2). Galactosylated substrates are useful biomaterials in the preparation of scaffolds for hepatocyte cultivation because of their specific interaction of the galactose moiety with the cell surface ASGPR [20].…”

Spherical biocarriers were prepared with lignin-carbohydrate complexes isolated from ginkgo (Ginkgo biloba L.) xylem. The specific surface and average pore size of the biocarriers were 17.15 m 2 g −1 and 21.59 nm, respectively. The carriers were stable in solution at pH 4.0∼9.5. Fourier transform infrared (FT-IR) spectrum indicated that the spherical carrier was composed of lignin and polysaccharides and had a typical lignin-carbohydrate complex (LCC) structure. The contents of galactose, lignin, and total sugar were 3.30%, 23.9%, and 64.62%, respectively, making the spherical biocarriers have good physical strength and compatible with hepatocytes. It was observed using a scanning electron microscopy (SEM) that liver cells adhered to the spherical biocarriers during culture. Cell counting indicated that the proliferation of liver cells in the experimental group was significantly higher than that of the control group. The albumin secretion (ALB) value and glucose consumption of the human hepatocytes were increased by 51.7% and 38.6%, respectively, by the fourth day when cultivated on the biocarriers. The results indicate that ginkgo LCC is very biocompatible and shows promise for the use as a biomaterial in the culture of human hepatocytes.

Lignin ist ein reichlich vorhandenes Biopolymer mit hohem Kohlenstoffgehalt und hoher Aromatizität. Trotz seines Potenzials als Rohstoff für die Kraftstoffherstellung und die chemische Industrie ist Lignin noch immer das am wenigsten genutzte Biopolymer der Lignocellulose. Zur effektiven Aufwertung von Lignin ist eine sorgfältige Feinabstimmung mehrerer vorgeschalteter Prozessstufen (d. h. Biotechnik von Lignin, Abtrennung von Lignin und katalytische Umwandlung von Lignin in der Anfangsphase) und mehrerer nachgeschalteter Prozessstufen (d. h. Depolymerisation und Verwertung von Lignin) erforderlich, die den Einsatz und das Zusammenwirken eines breiten Spektrums wissenschaftlicher Disziplinen erfordert. Dieser Aufsatz liefert eine Analyse der neuesten Fortschritte bei der Verwertung von Lignin “vom Anfang bis zum Ende”. Besonderes Augenmerk liegt auf dem verbesserten Verständnis der Biosynthese und Struktur von Lignin, den Unterschieden in Struktur und chemischer Bindung zwischen nativen und technischen Ligninen, den neu aufkommenden Verfahren der katalytischen Verwertung und den Zusammenhängen zwischen Ligninstruktur und Katalysatorleistung.
