Lignin— A botanical raw material

Microbiological Aspects of Lignin Degradation 1

“…A phenomenon which needs to be considered in studies on lignosulfonate is the possibility of a reaction between the proteinaceous mycelium and the lignosulfonate. This would be somewhat like the tanning of leather, for which process lignosulfonate derivatives are already in use (11). Day, Gottlieb and Pelczar (21a) have found that Polyporus versicolor, grown on a chemically defined liquid medium containing 2 per cent glucose and 0.5 per cent sodium lignosulfonate produces an apparent reduction of the lignosulfonate approaching 80 per cent.…”

“…United States (11). Of this total, more than 100 million tons were left either as waste in the woods or as waste in the manufacture of wood products.…”

The Biological Degradation of Lignin1

“…rhe possibility was considered that the concentration of lignosulfonate or methoxyl on the surface of the mycelium was a function of the acidity of the solution, a situation related to the tanning reaction, since cer-DAY, GOTTLIEB AND PELCZAR tain preparations of lignosulfonate have been employed as tanning agents (Brauns, 1948). Therefore, an experiment such as recorded in table 1 was performed with the addition of 0.5 g of calcium carbonate per culture flask.…”

Recent Advances in Preparation and Supercapacitor Applications of Lignin-Derived Porous Carbon: A Review

“…For example, Carl F. Dahl, who is a German chemist, patented and developed the pulping process by employing the hot solution of sodium hydroxide and sodium sulfide to produce pulp by breaking bonds between lignin, hemicellulose, and cellulose in wood in 1884, which was later called as "Kraft pulping" [32]. Then, P. Klason reported the macromolecular structure and the element composition of lignin in 1908 and 1920, respectively [33][34][35]. In the past decades, tremendous research efforts have been devoted to the elucidation of the structure of lignin and development new methods for its isolation/separation.…”
