摘要： Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins. The collagen or collagen-like proteins are isolated from animal sources or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.

摘要： A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers).

摘要： The invention is directed to a composite material comprising a biofabricated material and a secondary component. The secondary component may be a porous material, such as a sheet of paper, cellulose, or fabric that has been coated or otherwise contacted with the biofabricated material. The biofabricated material comprises a uniform network of crosslinked collagen fibrils and provides strength, elasticity and an aesthetic appearance to the composite material.
