Kitasatoa kauaiensis, a new species of the genus Kitasatoa, belonging to the family Streptoplanaceae, produces 3 kinds of antibiotics in a culture broth. These antibiotics were identified as chloramphenicol, bottromycin and fradicin based on their physico-chemical and biological properties. A new differential bioassay method for chloramphenicol and bottromycin produced in the same culture broth was established.
