Abstract:

Five commonly used active dry yeasts for grape wine were differentiated and identified by molecular biological techniques. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and inter-δPCR were used to differentiate and identify at subspecies or even strains level. Five unique inter-δPCR amplification patterns were obtained and molecular sizes of amplified products were predicted.

Key words: active dry yeasts, grape wine, differentiate and identify, PCR-RFLP, inter-δPCR
