The efficacy of monoethanolamine and sodium bisulfite pulping black liquors at three concentrations of 1; 1,5 and 2% on the preservation of poplar wood from white rot (Trametes versicolor) was investigated. The wood specimens were impregnated with the black liquors using a full-cell method. The black liquors enhanced the decay resistance without any reduction in mechanical strength, and a remarkable increase was observed at higher concentrations and weight gain percentage. The performance of monoethanolamine black liquor was more pronounced, probably due to lower kappa number and higher pH. The durability class of specimens impregnated with 2% monoethanolamine and sodium bisulfite black liquors improved from 5 (not durable) to 1 (very durable), and from 5 to 3 (moderately durable), respectively. Chemical analysis showed that the presence of additional lignin in wood alters the white rot. Results of anatomical studies showed that the fibers of the control and impregnated wood specimens were collapsed after 16 weeks of incubation. Leaching tests confirmed that the fixation of black liquors in wood should be examined for further studies.

“…The importance of lignin in wood composites has been recognized since the 1920s (Mason 1928). Lignin could act as a binder (especially in wet environments) (Mason 1928;Byrd 1979;Suchsland and Woodson 1986;Back 1987;Angles et al 2001), as a bio-protection agent (Agbor et al 2011;Chirkova et al 2011), and as a water repellent (Horn 1979;Winandy and Rowell 1984;Hosseinaei et al 2011;Klüppel and Mai 2012). However, it is apparent that more work is required to understand how the lignin and/or lignin-derived compounds (deposited on the surface of wood fibers) and the structural changes of wood resulting from thermal treatment (e.g., change of porosity) impact the manufacturing process and the properties of wood composites.…”

A review of wood thermal pretreatments to improve wood composite properties

et al. 2013

The objective of this paper is to review the published literature on improving properties of wood composites through thermal pretreatment of wood. Thermal pretreatment has been conducted in moist environments using hot water or steam at temperatures up to 180 and 230°C, respectively, or in dry environments using inert gases at temperatures up to 240°C. In these conditions, hemicelluloses are removed, crystallinity index of cellulose is increased, and cellulose degree of polymerization is reduced, while lignin is not considerably affected. Thermally modified wood has been used to manufacture wood-plastic composites, particleboard, oriented strand board, binderless panels, fiberboard, waferboard, and flakeboard. Thermal pretreatment considerably reduced water absorption and thickness swelling of wood composites, which has been attributed mainly to the removal of M. R. Pelaez-Samaniego

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.
