Abstract:
Monitoring substrate and cell concentration is important for controlling yeast propagation and fermentation processes. This usually requires two instruments, a density meter, and an optical turbidity meter. This paper presents a method for simultaneously determining yeast and maltose concentration with a single ultrasonic sensor. Ultrasonic velocity and attenuation were measured at varying maltose and yeast cell concentrations from 0 to 4 wt%. Ultrasonic velocity increased linearly with both yea...     »
