Detection of biofilm formation by ultrasonic Coda Wave Interferometry

The biofilm formation on food-contact-surfaces is a serious threat for public health and often results in huge human economic losses. Thus, it of importance to develop new strategies that allow the monitoring food-contact-surfaces. Such permit effective timely countermeasures and, therefore, avoid microbiological risk associated environmental impact due cleaning processes. Therefore, this work investigated non-invasive method detection using Coda Wave Interferometry (CWI) method. principle calculation decorrelation coefficient based ultrasonic measurements were explained. underlined our developed able detect early stage Staphylococcus aureus stainless steel. Namely, shown bacterial cell kinetic well captured by evolution as function incubation times. Overall, showed cost CWI promising tool
