Environmental Listeria test strips| First, the operation method | Second, read the manual |
3M™ Petrifilm ™The Environmental Listeria (EL) test strip is a pre-prepared culture medium containing selective reagents, nutrients, cold-water-soluble gels, and a chromogenic indicator for colony detection. Listeria number in the environmental samples was counted.The Listeria species detected by the Petrifilm EL test piece included L. monocytogenes L.innocua, L.grayi / murrayi, L.welshimeri, but can not distinguish between various bacteria.
Environmental conditions and disinfectants may inhibit or damage microorganisms Buffered Peptone Water (BPW) can be used as a repair broth in combination with Petrifilm EL test strips, but Listeria monocytogenes in buffered peptone buffer Not the enrichment step. |
