chromogen[′krō·mə‚jen] (biochemistry) A pigment precursor. (microbiology) A microorganism capable of producing color under suitable conditions. Chromogen according to the color theory devised by O. Witt, a substance containing chromophores—groups of atoms responsible for the coloration of various compounds. The term was also used to designate colorless substances found in animal and plant tissues that become pigments as a result of oxidation. V. I. Palladin proposed the term “respiratory chromogen” as part of his theory of plant respiration in reference to substances that become pigments through reversible oxidation. The equivalent Russian term is no longer used in the literature. chromogenenUK
