He then filled in the skeleton’s holes with ethyl cellulose, a tough biodegradable polymer.

Electrospinning using a starch-rich ingredient such as white flour is more challenging than using pure starch, as the impurities -- the protein and cellulose -- make the mixture more viscous and unable to form fibres.

As the mold digests the proteins and starch within the fibrous pulp, it also breaks down the cellulose, turning what remains into a dish beloved by many across western Indonesia.

The process involves blending three main components -- carbon nanotubes, polyvinyl alcohol and carboxymethyl cellulose -- followed by freeze-drying.

Biofuel production relies on the breakdown of compounds like starch or cellulose into glucose, which can then be efficiently fermented into ethanol for use as a fuel or converted into other useful materials.
