S. marcescens IBB Po15 cells grown at 37°C produced protease and the enzyme production decreased in cells exposed to aromatic compounds, as compared with the control cells. Seed culture and optimum growth condition. Listeria monocytogenes and Serratia marcescens had an optimum growth at a temperature of 35ºC, after which there was a steep decline in bacterial growth due to bacterial death. Bacteriol. Mutants lacking HexS over-produce the first enzyme in prodigiosin production, encoded by the pigA gene (and . This is owing to the fact that ribosome and enzyme deactivation may occur at temperatures below or above the optimal temperature (30 °C). A factorial design was applied to generate a set of 32 experimental combinations to study the optimal conditions for pigment production using crude glycerol obtained from local biodiesel facility as carbon source for the growth of Serratia marcescens. Transmission is by direct contact. The optimal temperature for growth and lipase production was 25°C, as also reported for Cryptococcus sp. something marvelous) (1, 2.)
