MSP MEDIUM
מק"ט: M5167.1000
- 1 kg
- MSP (Modified Sucrose Peptone) medium is a suitable medium for the detection of Pseudomonas savastanoi pv. phaseolicola (Pspha) and Pseudomonas syringae pv. syringae (Pss).
- Addition of bromothymol blue gives this medium a blue appearance.
- The color of bacterial colonies is influenced by this compound.
- The assay starts with dilution plating of bacterial extract from seeds on MSP. Then suspected colonies from MSP can be transferred to King’s B Medium (K5165).
- Finally, the identity of suspected isolates is confirmed by a pathogenicity test or PCR. Colonies of Pspha and Pss are ca. 3 mm in diameter, circular, raised, globose, glistening and light yellow with a denser center
- The medium around Pspha colonies turns light yellow after three days of incubation.
- For detailed information about Duchefa’s Phytopathological media have a look at our specialized brochure about this topic.
