Assessment of survival of food-borne microorganisms in the food chain by fluorescence ratio imaging microscopy

摘要: Traditionally, many data on food-borne microorganisms are obtained as an average of a whole population, under the assumption that individual cells clonal and therefore identical. However, it is now acknowledged there may be large heterogeneity within isogenic consequently new methods focus cells. This mini-review will give overview response microorganisms; i.e. pathogenic bacteria, lactic acid yeasts, at single-cell level to various food-related stress conditions, comprising acid-, disinfection-, salt- sugar- bacteriocin stress, assessed by Fluorescence Ratio Imaging Microscopy.
