The PFGE analysis results of 50 clones, each isolated from cultures of two lager strains (P and Q), after passage of 700 generations in wort or YEPD, showed that small chromosomal DNAs (I, VI and III) are susceptible to changes during successive cultivation. These changes may be strain‐dependent (P > Q) and the media may also affect the instability in the chromosomal DNAs (YEPD > wort).
