Recoveries of Salmonella ndolo from desiccates exposed to 100 degrees C under various conditions with respect to desiccant, desiccant temperature and atmosphere.

Desiccates of Salmonella ndolo dried in sodium glutamate have been exposed to 100 degrees C. in air or in vacuo; in the presence of wet or dry P(2)O(5); and with desiccant maintained at either 25 degrees or 100 degrees C. Of the eight treatments thus compared, rapid killing occurred where the desiccate was heated in vacuo and in the presence of dry P(2)O(5) maintained at 100 degrees C. There was little difference among the death-rates of the other seven treatments. Sublimation of the P(2)O(5) with resultant attack on the desiccate would appear to be responsible for the rapid killing in the treatment where it was observed.
