Title:
METHOD FOR CULTURING TRYPTOPHAN SYNTHASE PRODUCING BACTERIA
Document Type and Number:
Japanese Patent JPH04152883
Kind Code:
A
Abstract:
PURPOSE: To stably culture a microbial cell having a tryptophan synthase contained in a high activity in a high concentration by aerobically culturing a microorganism while retaining the pressure in a culturing can body to a specific value or below.
CONSTITUTION: Tryptophan synthase producing bacterium [preferably Escherichia coli K-12 YK2009] (FERM P-8957), etc.] is aerobically cultured while the pressure in a culture can body to ≤0.8kg/cm2, preferably 0.2-0.5kg/cm2 gage pressure.
