Abstract

The use of photoacoustic spectroscopy (PAS) as a new biofilm monitoring technique is presented. Growth and detachment of biofilms at three different positions inside a flow channel were monitored by photoacoustic measurements in the visible spectral range (lambda = 532 nm). The experimental approach allows the investigation of the influence of various process parameters (e.g. pH or flow conditions) on growth and detachment of biofilms. In addition, the distribution of the attached biomass can be monitored by depth-resolved photoacoustic measurements.

摘要

介绍了将光声光谱法（PAS）用作一种新型生物膜监测技术的情况。通过在可见光谱范围（λ = 532 nm）内进行光声测量，对流动通道内三个不同位置的生物膜生长和脱落情况进行了监测。该实验方法能够研究各种工艺参数（如pH值或流动条件）对生物膜生长和脱落的影响。此外，可通过深度分辨光声测量来监测附着生物量的分布情况。
