Abstract

In a process for digesting lignin-containing substances, the protozoa and bacteria predominantly living in symbiosis with termites are used.

Description

Beschreibung description

Die Erfindung betrifft ein Verfahren zum biologischen Aufschluß von ligninhaltigen Substanzen, z.B. Holz und Stroh.The invention relates to a method for the biological digestion of lignin-containing substances, e.g. wood and straw.

Die Verwertung solcher Biomassen, z.B. in anaeroben Prozessen oder als Futter bei Wiederkäuern scheitert daran, daß es in keiner Phase des Prozesses, sowohl der der Ssurebildner als auch der Methanphase, diesen Bakterien gelingt gegen den widerstand des Lignins Zellulose abzubauen.The utilization of such biomass, e.g. in anaerobic processes or as feed for ruminants fails because in no phase of the process both that of the acid generator and the methane phase, these bacteria succeed against the resistance of the lignin to break down cellulose.

Es ist bekannt, daß im Darmtrakt, vorwiegend bei Termiten in Symbiose lebende Urtierchen und Bakterien dazu in der Lage sind.It is known that in the intestinal tract, predominantly in termites, in symbiosis living primeval animals and bacteria are able to do so.

Es wird vorgeschlagen diese Urtierchen und Bakterien den Termiten zu entnehmen, sie in Nährlösungen nach bekannten Verfahren zu vermehren und mit ihnen Lignin aufzuschlieBen.It is suggested that these primeval animals and bacteria are called termites to see, to multiply them in nutrient solutions according to known methods and with to break them down with lignin.
