Abstract

The quantitative determination of biomass in a suspension by means of ultrasound velocity is a simple and on-line-applicable method. Such an ultrasonic sensor offers the advantage of being long-term stable, reliable, and sterilizable. In this paper we present sound velocity measurements made with different microorganisms. The experimental results which we have obtained with an impulse-echo method will be compared with theoretical predictions and discussed with respect to previous findings (Y. Ishimori, I. Karube, and S. Suzuki, Appl. Environ. Microbiol. 42:632-637, 1981).

摘要

通过超声波速度定量测定悬浮液中的生物量是一种简单且可在线应用的方法。这种超声传感器具有长期稳定、可靠和可消毒的优点。本文介绍了使用不同微生物进行的声速测量。我们将比较使用脉冲回波法获得的实验结果与理论预测，并结合以前的发现进行讨论（Y. Ishimori、I. Karube 和 S. Suzuki，Appl. Environ. Microbiol. 42:632-637, 1981）。
