mTBM Medium (modified TBM medium) is used to detect Xanthomonas hortorum pv. carotae (Xccar). Other semi- selective media for Xanthomonas campestris pv. carotae are mKM Medium (K5125) and mD5A Medium (D5124). The colonies of Xanthomonas hortorum pv. carotae on mTBM plates are white or yellow or white-yellow, glistening round, convex with entire margins and surrounded by a large clear zone of casein hydrolyses. For detailed information about Duchefa’s Phytopathological media have a look at our specialized brochure about this topic.
