| Abstract: | S ummary : Malt extracts prepared from barley and sorghum malts were used as media for preserving bacteria at -196°. The results are compared with those obtained with other protective substances such as dimethylsulphoxide, glycerol, malic acid, sucrose and sodium glutamate. The malt extract medium is recommended for use in the food industry. |
