DNA analysis of nonpathogenic clostridia isolated from cheeses
 Chroboková, Maria ; Trachtová, Štěpánka (referee) ; Španová, Alena (advisor)
Polymerase chain reaction (PCR) is a molecular method which allows in vitro replication of nucleic acids. It allows the identification and quantification of microorganisms or to prove specific gene sequentions in different matrices of biological origin. Some nonpathogenic species of genus Clostridium cause damages of cheeses, so their identification and quantification is very important in cheesemaking. In this thesis, specific primers for genus Clostridium were tested. Bacterial DNA from culture collection strains and from strains isolated from damaged cheeses were used. Genus-specific region for Clostridium was amplified using specific primers. The PCR products (619 bp) were detected using electrophoresis in 1,8% agarose gel. Genus-specific character of primers was confirmed. DNA of Lactobacillus was used for negative control.
