Abstract
The present invention includes a process for separating cells from a liquid media, a method of fermentation using such a separation, and an apparatus for conducting such a separation or for facilitating a cellular reaction. In broadest terms, the separation process of the present invention is a process for separating cells from a liquid containing cells. The process comprises the steps of: (a) bringing the liquid containing the cells into contact with one or more microbial polysaccharide and a fibrous material so as to adsorb the cells onto the fibrous material; and (b) separating the liquid from the fibrous material so as to remove the cells from the liquid. The process of the present invention may be used to remove cells from any liquid, but such liquids typically will be aqueous solutions, such as growth media, biological fluids, diagnostic samples, aqueous test samples, etc.
