Abstract:	By using our previously optimized media and a fed-batch operation controlled by LabVIEW Software, the key parameter for a high production of alkaline protease using the marine bacterium, Teredinobacter turnirae, was to maintain a low concentration of C and N-sources ( < 2 g sucrose l⁻¹ and < 0.2 g NH₄Cl l⁻¹) using an appropriate fed-batch culture system. A maximum protease activity of 8250 U ml⁻¹was thus achieved.

Keywords:	alkaline protease fed-batch culture Teredinobacter turnirae
