Within the context of research on genetic analysis, molecular biology brings rapid and reliable answers concerning an eventual pathogen germs contamination (identification and detection). The sample preparation is an important step, which needs to be efficient without degrading the material, particularly DNA, RNA, or proteins.
Results were conducted in collaboration with LGN (Laboratory of Molecular Genetic of the Neurotransmission). E.coli and spores of B.globigii were lysed with Precellys kit compared to standard procedures. RNA extraction was performed from the 2 microorganisms following each sample preparation.
