Abstract

L-Arginine can be converted to L-citrulline with arginine deiminase which was found in the Streptococcus faecalis.Many factors affecting on the enzymatic activity were studied.The result shows that the optimum conditions are as follows:the strain age 20 h,37 ℃,pH 6.0,ρ(cetyltrimethylammonium bromide(CTAB))=0.30 g/L.Some metal ions such as Cu~(2+),Zn~(2+)and Co~(2+) also have effect on the enzymatic activity.
