Abstract

PURPOSE: To include living microbial cells almost completely in a gel without damaging the cell, by applying an aqueous suspension containing polyvinyl alcohol and the living microbial cells to a plate having aligned protrusions, and freezing, forming and vacuum-drying the suspension.
CONSTITUTION: Living microbial cells are dispersed in an aqueous solution of a polyvinyl alcohol having a saponification ratio of ≥95mol% and a viscosity- average molecular weight of ≥1,500, or in an aqueous dispersion containing said vinyl alcohol and a clay mineral having lamellar structure composed of a 3- layered (2:1-type) composite layer as basic unit, e.g. montmorillonite, vermiculite, etc. The dispersion is applied to a flat or curved plate ving 900W500,000 protrusions per 1m2 to a thickness of 0.01W5mm, and frozen and formed at ≤-6°C. The formed article is vacuum-dried to a dehydration degree of ≥15% without melting, and if necessary immersed in water.
