BIOTIC is an ongoing research project to the possibilities of a biologically grown material. In this material research microbes are used to grow a biological material. This material is made of bacterial cellulose. Bacterial cellulose is made using yeast and bacteria in a fermentation process. Each bacterial cellulose sheet has a different translucency, which affects the applied colour. After the growing process Studio Lionne van Deursen experimented with different natural plant dyes and dyes made from fruitwaste. This material archive results in a collection of fabrics with different colours, translucency and textures.
