This little “dress” has been conjured from just thin air and sunlight. Various groups are investigating the use of bacterially derived materials for BioDesign, and most notably, the production of bacterial cellulose using Gluconoacetobacter xylinus or Kombucha . The production of these materials, however, relies on the provision of some feedstock for the bacteria, usually in the form of refined sugar, the production of which is energy intensive. Here scientists at C-MOULD have grown a small dress using the cyanobacterium Oscillatoria animalis, sunlight and air.
Cyanobacteria are aquatic and photosynthetic bacteria that have been hugely important in shaping the course of evolution and the content of the Earth’s atmosphere, but here one has been put to use to assimilate sunlight and carbon dioxide to produce a unique and sustainable BioMaterial.
This is a first test on a small scale but more larger scale tests are planned.
