Abstract
A binding agent comprising fiber strands of microbially produced cellulose is disclosed. The cellulose is synthesized by certain strains of microorganisms of the genus Acetobacter grown under agitated culture conditions to produce fine, interconnected fiber strands forming a three-dimensional reticulated structure. The binding agent is effective for binding fibers and fragments of material, such as natural and treated wood fragments and particles as well as synthetic materials, and it imparts wet and dry tensile strength to the bound material.
