Micrococcus luteus produced 29 {mu}M riboflavin during growth on 6.5 mM pyridine but not during growth on other substrates. On the basic of the results of radiolabelling studies, riboflavin was not directly synthesized from pyridine. Pyridine may interfere with riboflavin biosynthesis or elicit a general stress response in M. luteus. The optimum concentration of pyridine for both growth of the organism and pyridine degradation was 13 mM. Above 25 mM, pyridine temporarily inhibited growth, pyridine degradation, oxygen uptake, and pigment production.
