Xylinum is a research project that asks: “What could future materials and production processes look like?” It has been known for a long time, that micro-organisms can be used for industrial processes, like yeast cultures for production of bread, alcohol or cheese. Since it is possible to decode the DNA of organisms, and even to change it consciously, the so called “White Biotechnology” has changed fundamentally. Now it has become possible to replace chemical by organic processes. This already has happened in the textile and detergent industry and shows big potential in the production of energy or plastics. Bacterial-cellulose is such a material, which is produced by a bacterium called Acetobacter Xylinum. In a nutrition liquid it transforms sugar into a cellulose-fibre structure. The project was realized in collaboration with the company Jenpolymers in Jena, which developed the technique that makes it possible to shape the material already during the production process inside the liquid.
