Abstract :

SIGNALMAN is an industrial collaboration between MiCRA Biodiagnostics and the Dairy Processing Technology Centre, a University of Limerick based dairy industry consortium. The project involves the engineering of automated biosensors to detect and enumerate spore-forming bacteria in milk and dairy processing lines. Quality control of processed milk and associated products is of extreme importance to the dairy industry since a variety of micro-organisms is responsible for product quality issues, reduced shelf life and spoilage. Spore-forming bacteria such as Bacillus cereus are identified in milk products by traditional culture and colony counting techniques. These procedures require three days to process samples resulting in serious and costly production delays. It has therefore become essential to develop new technologies to rapidly detect B. cereus during dairy processing. MiCRA Biodiagnostics is involved in the advancement of electronic biochip technology for the rapid detection of B. cereus spores. This biosensor technology relies on immunoassay-ELISA principles and comprises sample-reagent microfluidics and redox-measuring electrodes. The B. cereus BIOCHIP is currently being adapted for biosensor applications in SIGNALMAN.
