Protein Biomanufacturing

Protein biomanufacturing entails the large-scale production of proteins using living cells such as bacteria or yeast. Tandem Repeat has developed a patented fermentation microbial process that transforms proteins into valuable products, including textile fibers and nonwovens. This process encompasses synthetic biology, strain and fermentation engineering, and downstream processes. To optimize biomass fermentation, it is essential to carefully control parameters such as temperature, pH, nutrient availability, and microbial strain selection to achieve high product yields, titers, and productivity, ultimately rendering the process economically viable and environmentally sustainable. Biofermentation offers a less toxic alternative to plastics (e.g., polyester, nylon and acrylic) as well as animal or plant products for sustainability. Procell’s greenhouse gas emission footprint (5.39 kg of CO₂/kg), water usage (0.52 m³/kg), and land usage (12.4 pt/kg) are lower than any natural fiber products, including cotton, lyocell, and wool.
