In this new study, proteins were extracted from the yeast, dissolved in a solvent, and forced through a spinneret to create continuous fibres, which were then spun into yarn.

US researchers have developed a sustainable, protein-based fibre using the yeast biomass remaining after alcohol and drug production.
The fibre is stronger than natural fibres and can be produced for USD 6 or less per kilogram (compared to USD 10-USD 12 for wool).
