Technical Feasibility
This technology involves installing an AE sensor with a sensitive part directly contacting the microbial culture solution or medium, and analyzing the AE signals with a signal processing unit. This can be achieved by integrating a general-purpose AE sensor into existing culture devices or bioreactors and implementing a software-based signal processing algorithm. Significant equipment changes are not required, as the focus is primarily on sensor and software integration, suggesting a relatively low technical barrier to adoption.
Success Scenario
Implementing this technology could enable real-time monitoring of microbial contamination risks in food production lines and bioreactors, allowing for immediate alerts upon anomaly detection. This has the potential to significantly reduce the waiting time for results, which typically takes several days with conventional methods, potentially shortening product shipment lead times by 20%. Furthermore, early identification of contaminated batches is estimated to reduce discarded product volume by 15%.
