TY  - JOUR
AB - Bacterial cellulose is a strong and ultrapure form of cellulose produced naturally by several species of the Acetobacteraceae. Its high strength, purity and biocompatibility make it of great interest to materials science, however precise control of its biosynthesis has remained a challenge for biotechnology. Here we isolate a new strain of Komagataeibacter rhaeticus (Komagataeibacter rhaeticus iGEM) that can produce cellulose at high yields, grow in low nitrogen conditions, and is highly resistant to toxic chemicals. We achieve external control over its bacterial cellulose production through development of a modular genetic toolkit that enables rational reprogramming of the cell. To further its use as an organism for biotechnology, we sequenced its genome and demonstrate genetic circuits that enable functionalization and patterning of heterologous gene expression within the cellulose matrix. This work lays the foundations for using genetic engineering to produce cellulose-based materials, with numerous applications in basic science, materials engineering and biotechnology.
