the bacteria dyes itself. Researchers started out by genetically modifying Komagataeibacter rhaeticus, the best-studied and the most efficient cellulose producer. They then changed its tyrosinase ...

A UK start-up is producing dyes made by bacteria and yeast rather than fossil fuel-derived chemicals, which could help clothes manufacturers cut energy use and pollution ...

Researchers at Imperial College London have genetically engineered bacteria to grow animal- and plastic-free leather that dyes itself. In recent years, scientists and companies have started using ...
