Sols prepared by the method can be sterilized by heat treatment and are stable for some weeks. Bacteriological media can easily be prepared with such sols and the gelling time regulated by the concentration of sodium chloride used. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-4-2-235
