Bleached polyacrylic acid crosslinked cellulosic fibers, methods for making the fibers, and products including the fibers. The bleached polyacrylic acid crosslinked cellulosic fibers are polyacrylic acid crosslinked cellulosic fibers that have been treated with one or more bleaching agents to provide crosslinked cellulosic fibers having improved whiteness.

A suspension of bacterial cellulose having a reticulated structure has been conditioned to remain in suspension when the suspension is under shear so that it may be coated on a substrate. The suspension of bacterial cellulose is homogenized and thereafter filtered to provide a bacterial cellulose component having a size no greater than 125 microns. This allows a process for applying bacterial cellulose as a coating on a substrate on a substantially continuous basis, either by roll coating or spraying. It also provides a coated product in which the bacterial cellulose is substantially uniform, taking into account the normal discontinuities of roll coating and spray coating.

Particulate materials, particularly fine particles of clay animal litter, are agglomerated using a reticulated cellulose product formed by growing Acetobacter. Treatment with such reticulated cellulose also enhances the liquid absorbency of particulate materials.

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.

The invention is a method of binding a portion of the cholesterol present in an aqueous suspension, such as the digestive system of a mammal. It involves the use of a purified bacterial cellulose in a sufficient amount to absorb or bind at least a portion of the cholesterol present in the system. The bacterial cellulose provides a dietary fiber component and is preferably one produced by a bacterium of the genus Acetobacter cultured under agitated aerobic conditions.
