Abstract: 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.
