Isolation of DNA from probitic products using solid carriers
Bonczek, Ondřej ; Horák, Daniel (referee) ; Rittich, Bohuslav (advisor)
Microbial DNA was isolated from lysed cells of Lactobacillus genus in probiotic products. Reversible adsorption DNA on the surface of carboxyl coated nonporous poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) (P(HEMA-co-GMA)) magnetic particles and silicagel coated manganase Perovskite nanoparticles. DNA was adsorbed on the surface of the particles in the presence of 16 % poly(ethylenglycol) (PEG 6000) and 2 M sodium chloride (NaCl) concentrations. The adsorbed DNA was released from particles by low ionic strength TE buffer (pH= 8.0). The quality of isolated DNA was checked by spectrofotometric measurement and PCR amplification. DNA samples isolated using magnetic particles and phenol extraction method (control method) were PCR-ready. The DNA isolated from lysed cells of probiotic products was quantificated in real-time qPCR.
