Abstract : At chill temperatures, Pseudomonas fluorescens produces inducible extracellular protease and lipase. Their regulation by growth temperature and conditions was studied in chemostat experiments and by the use of a transcriptional fusion in the structural lipase gene. The findings suggest two levels of temperature regulation of lipase production, resulting in maximal activity at about 17°C, well below the optimum for growth.
