title: Bacteriocin-like substance (melaninocin) from oral Bacteroides melaninogenicus.
abstract: A bacteriocin-like substance, designated melaninocin, was extracted from a strain of Bacteroides melaninogenicus by ultrasonic treatment and purified. Melaninocin was heat labile and was destroyed by digestion by several proteolytic enzymes. Among the oral indigenous microorganisms, Bacteroides, Actinomyces, and streptococci were found to be sensitive to melaninocin.
