We discovered that the Bacillus licheniformis SSA3, fermenting traditional Korean soy sauce and soybean paste, involved in the synthesis of a dark-brown pigment. This pigment produced in the minimal medium supplemented with tyrosine only as precursor. We showed that this pigment is novel, and differed from melanoidin and melanin, and an antimutagenic substance.
