abstract：:The arginine deiminase system was found to function in protecting bacterial cells against the damaging effects of acid environments. For example, as little as 2.9 mM arginine added to acidified suspensions of Streptococcus sanguis at a pH of 4.0 resulted in ammonia production and protection against killing. The argini...
