Abstract:	During the bacterial production of cellulosic films on non-agitated liquid media, the mass of the system does not change. An equation is therefore proposed to evaluate the volume of inoculated medium to be placed in a given tray so that, when no more free aqueous medium may be detected under the wet pellicle produced, a dried film of a desired average thickness is produced.

Keywords:	Acetobacter xylinum bacterial production of cellulose fermentation control
