MD5A MEDIUM

מק"ט: D5124.1000

  • 1 kgm
  • D5A (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.
  • For detailed information about Duchefa’s Phytopathological media have a look at our specialized brochure about this topic.
  • Brochure can be found at the “Brochure section” at the home page of this website.
