Definitions
- the present invention relates to a novel method for
- waste water in particular paper mill or pulp waste water.
- Pulp production Use of lignolytic enzymes: biopuiping.
- Processes include the sulfate and sulfite processes. With both processes, boiling and under pressure, cellulose ej-zeug: The sulfate process works with the active chemicals NaOH and Na 2 S. The sulfite process with Ca (HSO 3 ) 2 - SO 2 .
- the wood fabrication processes work with stone grinding (wood grinding) or with refiners (TMP). which the wood after
- wood pulps still contain a large part of the lignin and are mainly for printing newsprint or printing
- Biopulping is generally understood to mean using biological
- Cellulose or hemicellulose are dependent as a carbon source. This
- the main difficulty is the very slow one
- the rate of degradation of the lignin (days to weeks), so that in the in vivo process: wood chips + cellulase-less - mutants (Phanerochaete chrysosporium), among other things, at the screening of new ones better wild tribes works.
- the ultimate goal is to achieve faster and more effective lignin breakdown, especially the one above
- Phanerochaete chrysosporium Phanerochaete chrysosporium.
- Pulps used in the mechanical-thermal or chemo-mechanical or chemo-thermo-mechanical treatment of wood pulp Pulps used in the mechanical-thermal or chemo-mechanical or chemo-thermo-mechanical treatment of wood pulp
- the bleach is
- heme compounds e.g. also hemoglobin, which is quasi the active heme component in the
- the hemicellulases here u.a. the xylanases. are used as bleaching enzymes because one suspects an effect on the bonds between hemicelluloses (xyians) and the lignin.
- the enzyme has a long duration of action at relative
- lignolytic enzymes decolorization and detoxification of cellulose fabrication waste water and the oxidation and thus detoxification of chlorinated aromatics and others
- the present invention has now set itself the task.
- Oxidize lignin Oxidize lignin.
- German patent applications DE 3636208 (WO 88/03190).
- P 408894.4 describe the use of lignolytic enzymes with simultaneous addition of reduction and
- Laccase v.a. used by Coriolus versicoior This laccase is used together with laccase substrates
- Fig. 1 shows the mechanism of action of laccases on the
- the laccase catalyses the formation of a mesomeric aryloxy radical from phenol.
- Residual lignin content i.e. around 19% attempts to break down with the new one
- Residual lignin content i.e. by 41%, i.e. by more than double.
- the inventive method determined by means of a red-ox electrode and by means of a controller and actuator during the
- Reducing agents, salts and phenolic compounds are kept constant.
- Air, O 2 or hydrogen peroxide are preferably used as the oxidizing agent.
- Sodium bisulfite comes as a reducing agent.
- Metal salts are preferably used as salts. This is where FeSO 4 comes in. FeCl 3 . MnSO 4 . TiO 2 , CuSO 4 and Mn 3 acetate into consideration. It should also be noted that the addition of
- ethylenediamine tetraacetic acid EDTA
- EDTA ethylenediamine tetraacetic acid
- DTPA Diethylenetriamine-penta-acetic acid
- cathionic and ampholytic surfactants as well as glucans and
- Enzymes can also use hemicellulases and / or pectinases and / or lipases. The main difference to that in the work "Oxidation of non
- the system according to the Invention is either by means of laccase alone
- lignin peroxidases and / or manganese peroxidases from e.g.
- Phanerochaete chrysosporium or other white rot fungi used together. With the latter. Lignin peroxidase (manganese peroxidases) + laccase. is worked at a pH around 4-5, at which both enzyme species are still active. The actual lignin breakdown. the bleach (with
- Oxidizing agents i.e. by intercepting lignin degradation
- Yeast cell walls originate in mixed cultures between
- an additional bleaching system such as formamidine sulfinic acid (FAS) / NaOH can also be important to compensate for the bleaching effect of NaOH / HO in the chemical system, and also as a collector the addition of soaps alone or in
- Oxidizing agents H 2 O 2. O 2 or atmospheric oxygen allow an almost complete polymerization of lignins contained in the wastewater, which go far (20-50%) above the values that can be achieved with laccases alone. This makes it possible for 70-90% of the lignin to become insoluble and thus loosen up, sediment,
- the pH is adjusted to 5 with 1N HCl.
- 0.1 - 1.5% H 2 O 2 are related to dry matter, approx. 0.1% ETDA or DTPA.
