Summary Salmonella ndolo was suspended in a number of fluids, including solutions of sodium glutamate, various carbohydrates and long chain polymers, then dried on cellulose tufts and sealed in vacuo . Recoveries were measured after storage at room temperature, 37° and 45°, and after exposure to 100° for as long as seven hours. Glutamate had a highly protective effect towards the desiccates at the higher temperatures. A mixture of glutamate and peptone gave complete recovery after drying and after storage at room temperature for two years, and relatively high recoveries after high temperature storage and exposure to 100°. The recoveries of bacteria after drying in glutamate on cellulose or quartz fibres were very similar.
