A short time ago C-MOULD the world’s largest collection of microorganisms for use in art and design acquired  two strains of Gluconoacetobacter xylinus, which produce  cellulose nanofibres when grown with sugar. These are microscopic images of the bacteria and clearly show the bacterial cells amongst deposits and fibrils of cellulose.  It’s an intriguingly tough yet flexible living material and by growing the bacteria together with sand I’m hoping to grow my own house.
