An Electrophoretic Method for the Assay of Bacterial Variants

The temperature range of growth was 5-39.5 C. Candida krusei was able to grow at 46 C. Torulopsis albida was able to grow at 0 C. The sugar tolerance was 50-55O Brix syrup. Saccharomyces ro8ei and Torulopsis lactis-condensi were able to tolerate 600 Brix syrup. Attractivity tests with dried-fruit beetles indicated that they responded most to Candida krusei, then Hanseniaspora valbyensis, fig tissue, and Torulop8is carpophila, nov sp in that order. The rate of digestion of yeasts by the insects was rapid, most of the cells being destroyed at 25 C in 1-4 hours after feeding.
