is not taken into consideration.
This weakness can be addressed by the application of techniques such as PCR - DGGE,
Which instead of relying on culturing of the bacteria,
incorporates the direct extraction of the DNA from the food sample. Furthermore,
another technique that has not yet been applied in fermented sausages is fluorescence in situ hybridization (FISH).
In this technique, the direct detection of a microorganism in a food sample is achieved by using specific probes
that allow spatial distribution studies to take place.
