mKM medium (modified KM-1 medium) is used to detect Xanthomonas hortorum pv. carotae (Xccar). Contaminated seed lots can be detected by dilution plating of the bacterial extract on mD5A and another semi-selective medium. Suspected iso-lates are then transferred to YDC. Finally, the identity of the suspected isolates can be determined by PCR. The colonies of Xccar on mKM plates are light-yellow cream, light brown to peach yellow, glistening, round and about 2 – 4 mm in diameter.
