Abstract: Bacteria enumeration is the quantification of the number of viable bacteria cells in a given sample, and is a necessary procedure in the health and safety of several industries. Of particular interest is the food industry, where the current gold standard method for bacteria enumeration is plate counting. Where plate counting falls short is the length of time necessary for one test, taking approximately 2 to 5 days. Food cannot be released for consumption until tests have been complete. Consequently, food producers cannot make potential correct actions and need to store products during the wait – creating food wastage and increasing costs. Other bacteria enumeration techniques fail to improve the speed, accuracy, or costs of plate counting, and food producers are forced to rely on the 2 to 5 day way at best. Microfluidics has already been shown to enhance other analysis systems through a range of fluidic functions, such as reagent pre-storage and release, fluid transport, valving and switching, metering, mixing, and separation; making microfluidics a promising field to meet the needs of bacteria enumeration. This presentation will address what is currently hindering alternative bacteria enumeration techniques, and what microfluidics can offer to enhance these techniques.
