Abstract
The synthesis of prodigiosin by non-proliferating cells of Serratia ma rcescens was examined at various pH values between 5.5 and 9.5. During incubation in unbuffered medium, pH changed and prodigiosin productio n was similar regardless of the initial pH. Variations in pigment prod uction were noted when buffers were employed in cultures of non-prolif erating cells. The optimum pH for prodigiosin production was 8.0-8.5. Proline oxidase was also measured. The results suggest that the effect of pH may be related to the amount of proline which can be incorporat ed into prodigiosin.
