【Abstract】 DNA probe technology based on nucleic acid hybridization is a normal technique in modern molecular biology. Detection of pathogenic and spoilage micro organism in foods by DNA probe has the advantages of high specificity, sensitivity, simple and time saving. Some important development about DNA probe technology has been obtained in recent years which will certainly accelerate its application in the detection of food pathogens. The mechnism and application of various DNA probe techniques and the newest development have been rivewed in this paper.更多还原
