The basis of this plasticity was a subject of considerable dispute until the 1950s, since the activities of the enzymes required to metabolize a particular substrate were in most cases not detectable if the organism was grown on another.

Some reference to these characteristics was made in Chapter 1. However, it will be convenient to summarize them at this point.
