Relation between Growth and Luminescence

An important factor in the brightness of a given strain and its variants is the pH change induced in the medium. The most generally employed medium contains 1% glycerol, which favors growth and luminescence, but 

Semidark dissociants of bright stx-ains sometimes respond to an addition of lactoflavin by an increase in luminescence (54). 

The sensitivity of luminescence to many substances that cause harmful effects in animals invites preliminary tests for possible nontoxicity of new chemotherapeutic compounds. Unfortunately, the criterion is not
