Brewed Protein™

Brewed Protein™️ materials are the protein fibers, films, and other types of materials manufactured using Spiber’s proprietary fermentation (brewing) process. With a production process that utilizes plant-derived sugars as primary raw ingredients, Brewed Protein™️ materials are well placed to address increasing market pressure for animal-free, plastic-free alternatives in the apparel industry. The unique, customizable nature of Brewed Protein™️ materials also shows potential to fulfill growing demand in the automotive and aerospace industries for lighter-weight materials. Through an evolutionary and iterative optimization process which begins at the molecular level, Brewed Protein™️ materials can be tailored to suit the needs of specific applications in a range of fields and industries. [Production process of Brewed Protein™️ materials] At Spiber, we begin by designing the genes that code for the desired structural proteins. We then introduce those genes into microorganisms which are engineered to produce the protein in a highly productive manner. Raw materials such as sugars and minerals are required as sources of energy and nutrients for the microorganisms to produce proteins. In the Brewed Protein™️ production process, these raw materials are prepared in large-scale tanks, the microorganisms grow and multiply, and the proteins are produced at high efficiency via fermentation. After fermentation comes the purification process, in which proteins are separated from the liquid mixture containing the microorganisms. These purified proteins are then dried and the resulting Brewed Protein™ powder is processed into a variety of forms, such as fibers and films.
