Abstract

Sporulation of and was induced in a continuous tower fermenter by restricting growth by nutrient limitation. Shock carbon limitation produced no sporulation, but the gradual decrease of sucrose or starch supply to produced slight sporulation. Gradual nitrate limitation produced no sporulation, while a shock decrease in nitrate concentration caused heavy sporulation of both organisms. The previously unobserved morphology of the sporulating structures produced was much simplified under nitrate limitation, but similar to sub-aerial morphology under carbon limitation. Maintenance energy values for sucrose and starch were calculated for and for starch for . The continuous tower fermenter system was found to be ideal for controlling organism morphology and thus sporulation.
