MILD heating (up to 36°C.) is known to produce a small increase of the spontaneous mutation-rates in Drosophila and in bacteria. We have found that using special conditions it is possible to have mesophilic non-sporogenic bacteria (Escherichia coli) survive relatively high temperatures (60°C.) ; this sublethal treatment produces a high frequency of mutations and unstable genes.
