Most bacteria thrive well in media like the usual culture media containing albuminous substances. But also in this latter case great differences exist; while for instance, the bacteria occurring in water (bacillus fluorescens liquescens, bacillus sulcatus and others) can even when the water contains only traces of albuminous matter, well thrive therein and under.
