| Research Abstract |
To detect bacteria in foods simply and convenietly, we examined the conditions for amplification of a gene fragment of alanine racemase by polymerase chain reaction. Several primers corresponding to the regions of the active site and His168 to Glu174 of alanine racemase were synthesized and used for this study. Specific amplification of the gene fragment (400bp) was achieved when the PCR was performed at 94 C for 20 s for denaturation, at 54 C for 30 s for annealing, and at 72 C for 180 s for extension. the mehod was applicable for amplification of the gene fragment from various bacteria. When foods such as milk and mineral water containing bacteria was used as templates for the PCR,one bacterial cells in the foods was detected by the PCR.This method is useful for detection of bacteria in foods.
