  • Method for production of antimutagenic substance using lactic acid bacterium
    Patent number: 8440426
    Abstract: Disclosed is a method for producing an antimutagenic substance by using a lactic acid bacteria, which can produce the antimutagenic substance in a large quantity in an extremely simple manner and is economically advantageous; particularly a method for producing an antimutagenic substance effective for a carcinogenic substance, particularly a heterocyclic amine (HCA) which is a carcinogenic substance derived from a food, by using a lactic acid bacteria. Specifically disclosed is a method for producing an antimutagenic substance by using a lactic acid bacteria, which is characterized by suspending the lactic acid bacteria in a poorly nutrient or nutrient-free medium and leaving the lactic acid bacteria in the medium.
    Type: Grant
