Abstract
PURPOSE: A collibacillus capable of producing cytosine deaminase is cultured in a medium which is ajdusted in pH with citric acid to produce cytosine deaminase in high yield.
CONSTITUTION: A collibacillus capable of producing cytosine deaminase such as Eserichia coli K12 is cultured in a medium that contains 0.2W2wt% of citric acid and is adjusted in pH to 6.5W7.5, preferably about 7 at the start of cultivation. When the pH reaches 7.8W8.7, citric acid is added to adjust the pH to 7.0W9.2, preferably 7.8W9.2 and the cultivation is continued in this pH range.
