Definitions
- lignocellulose The main structure-forming elements of lignocellulose are cellulose, hemicellulose and lignin. Although proteins are also integral components of lignocellulose and are deposited in the course of biosynthesis in the plant cell wall, but their biological function in the cell wall is largely unknown or there is only speculation about it [1, 5].
- U.S. Patent No. 5,374,555 [5] discloses a process for delignifying lignocellulose with proteases.
- lignocellulose With proteases, Several examples demonstrate that treatment of lignocellulose with proteases facilitates and enhances the extraction of lignin from lignocellulose. This effect is attributed to the fact that proteins in lignocellulose form a cross-linked matrix that is bound to lignin, for example, and the hydrolysis of this protein network facilitates the removal of lignin from lignocellulose. That the extracted lignin itself could contain significant amounts of protein and that this protein has a substantial fraction of the molecular weight of this hypothetical lignin-protein conjugate is not disclosed in U.S. Patent No. 5,374,555 [5] nor is it possible recovery of peptides and / or amino acids from the hydrolyzate.
- Liang et al. [3] describe a molecular biology method for the in situ introduction of peptide-lignin crosslinks into the plant cell wall to enhance the release of polysaccharides by subsequent treatment of the lignocellulose with proteases.
- a possible influence of the protease treatment on the physico-chemical properties, for example on the molar mass of the treated peptide-lignin conjugates is not mentioned.
- the present invention is based on the recognition that lignin-protein conjugates are not only present in lignocellulose, but surprisingly even make up a considerable proportion of the total lignin.
- the comparatively low molar mass of the peeled peptides and / or amino acids and the particular chemical properties enable their separation from the remaining lignin derivative by additional process steps, for example by ultrafiltration and nanofiltration, extraction, precipitation or chromatography.
- the peptides and amino acids present in the hydrolyzate after the treatment with protease enzyme (s) are separated from the lignin derivative and further processed to separate products.
- An advantage of the process of the invention over conventional processes for reducing the molecular weight of technical lignin, e.g. thermal cleavage and cleavage by metal catalysts, is the reaction under mild conditions, i. at low temperature. As a result, the lignin can not decompose and remains substantially in its natural state in terms of chemical structure.
- Technical advantages of small lignins ?
- a particularly significant technical advantage of the method according to the invention is the provision of lignin derivatives which can be reacted enzymatically, for example by laccase much better to higher molecular weight polymers and thereby activate as non-deproteinized lignin. As stated below, such polymers have proven to be excellent binders for wood-based materials.
- DE 37992 C2 describes a process for producing a binder in which technical lignin is converted into an active binder for wood-based materials by polymerization with laccase and atmospheric oxygen.
- an activated intermediate is prepared in a similar manner from industrial lignin, which then in the presence of atmospheric oxygen and phenol oxidizing enzymes, such as laccase, reacted with non-activated technical lignins is formed, wherein polymeric lignin products are formed, which have a substantially higher molecular weight than in the non-activated lignin control reaction.
- the higher molecular weight of such activated technical lignins has proven to be synonymous with a higher binding force when used as a binder.
- deproteinized lignin derivative has a significantly increased reactivity and thus activatability than non-deproteinized technical lignin.
- the activation of a technical lignin with laccase and atmospheric oxygen carried out in a manner similar to that described in DE 37992 C2 and DE 19700908 A1 (WO 98/31729) led to an increase in the molar mass by 40%, whereas with the lignin derivative of the same technical lignin deproteinated according to the invention otherwise identical reaction conditions a faster polymerization and an increase in the molecular weight could be achieved by 167%.
- the polymerizability and associated activation of lignin is also highly suitable for the technical suitability of lignin derivatives as coating agents for papers and other vegetable fibers Reagents for the production of thermosets, for the production of fiber-reinforced Verwundtechnikstoffen, and as a binder for wood-based materials of crucial importance. Also for these applications, one can expect a technical benefit associated with the improvement of the activability of technical lignin which can be achieved in the process according to the invention.
- WO 98/31762, WO 98/31763 and WO 98/31764 also describe the use of technical lignins or soluble technical lignin / carbohydrate fractions from lignocellulosic substrates of phenol oxidizing enzymes for polymerisation polymerization. According to the prior art, it can be assumed that the reduction of the molar mass of a technical lignin by protease treatment brings about a corresponding quantitative release of peptides and / or amino acids.
- the process according to the invention can be used to prepare products from technical lignins, which advantageously consist essentially of peptides and / or amino acids and are only slightly contaminated with lignin, which results in recovery of Peptides and / or amino acids made from crude products prepared by the process of the invention can make economic sense.
- Example 1 lignin is made from straw and characterized in terms of molecular weight and lignin content. Based on this, Example 4 illustrates the actual core of the invention, namely the significant reduction in the molecular weight of lignin by protease treatment.
- Wheat straw is crushed to a particle size of about 2 cm.
- 2.5 g of crushed wheat straw is suspended in a 500 ml reaction vessel in 200 ml of a solution consisting of 50% water and 50% ethanol.
- the suspension is heated to 50 ° C. in a water bath, thermostated and the pH of the suspension is adjusted to a starting pH of 13 with aqueous NaOH solution.
- the mixture is stirred continuously at 200 rpm, 70 ° C., 24 h.
- the solid was then filtered off and the clear filtrate was adjusted to pH 2.0 with phosphoric acid.
- the resulting precipitate was dissolved in dimethylformamide (DMF) and separated by preparative gel chromatography on Sephadex LH60 in DMF into high and low molecular weight fractions.
- the DMF in the individual fractions was evaporated from the fractions in a high vacuum and the solid residue was homogenized in a mortar.
- Exactly weighed amounts of lignin fractions from Example 1 were analyzed on the one hand for protein content (CHN analysis) and on the other hand dissolved in DMF, followed by determining the UV absorption of these solutions at 280 nm in the spectrophotometer. The extinction coefficient was calculated by dividing weighed amount by total absorption at 280 nm.
- the extinction coefficient of the lignin at the absorbance maximum of 280 nm typical for lignin increases from high (fraction number 10) to low (fraction number 30) molecular weights by a factor of 4-5 from about 5 mg "1 to 20-25 mg " 1 . If, according to the prior art, it is assumed that the extinction coefficient of pure lignin is relatively constant and the fractions with the highest extinction coefficients (fractions 21-30) investigated in the present invention consist of almost pure lignin, then the high molecular weight fractions must be from to 80% (fraction 9) non-lignin exist.
