ABSTRACT:
The strength of a bead containing microbial cells within a retaining permeable membrane is improved by incorporating finely divided sericitic clay particles within a hydrocolloid-containing composition used to form the membrane. The hydrocolloid is preferably alginic acid, carboxymethyl cellulose, methylethylcellulose or polyvinyl alcohol in an amount of about 10 to 40% by weight.
