Product Overview
mD5A (modified D-5 Agar medium) is used to detect seed borne Xanthomonas campestris pv. carota (Xccar); the causal organism of bacterial blight of carrots. Contaminated seed lots can be detected by dilution plating of the bacterial extract on mD5A and another semi-selective medium. Suspected isolates are then transferred to YDC. Finally; the identity of the suspected isolates can be determined by PCR. Colonies of Xccar on mD5A medium look straw-yellow; glistening; round; smooth; convex and are 2–3 mm in diameter.
