Abstract
A systematic research was conducted for the isolation and identification of undesirable microorganisms in food products using molecular approach. The result revealed the presence of Yersinia aleksiciae and Pseudomonas fluorescens strains in Australian pasteurized milk and mixed salad respectively. Y. aleksiciae grouped as lacking virulence marker and is regarded non-pathogenic. P. fluorescens has been identified as a marker of spoilage of ready-to-eat vegetable salads. This study confirms the rapidity and sensitivity of 16s rDNA analysis in identifying strains which contribute in early monitoring, accurate analysis and control of microbial risks in food products. The described methodology has special relevance in food quality control and safety.
Author Comment
This study is investigating the isolation, identification and characterization of microbial strains from milk and mixed salad available in Australian markets.
