MFS MEDIUM
מק"ט: F5123.1000
- 1 kg
- mFS (modified Fieldhouse Sasser medium) has been developed to detect black rot in brassica.
- This medium is complementary to mCS20ABN (C5122) due to some alternative antibiotics.
- Modifications concern the addition of extra starch and omission of gentamycin.
- Contaminated seed lots can be detected by dilution plating of the bacterial extract on mCS20ABN and mFS.
- Suspected isolates are then transferred to YDC.
- Finally, the identity of the suspected isolates can be determined by a pathogenicity test using brassica seedlings.
- The colonies of Xanthomonas campestris pv. campestris (Xcc) and Xanthomonas campestris pv. amoraciae (Xca) on mFS medium are pale green to transparant, mucoid and surrounded by a small zone of starch hydrolysis.
- Colonies are in general smaller than on mCS20ABN and may show remarkable variation in size and may be visible only after 5-6 days.
- 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.
