在完全混合的管式循环反应器中监测污垢生物膜的发展。一个独特的采样系统允许直接（明场，落射荧光和扫描电子显微镜）和间接（增加流体摩擦阻力）的生物膜的观察。低流体速度（138.5厘米/秒）实验有较短的诱导时间和生物膜基质，其中包括牢固粘附的丝状细菌。高流体速度（265.4厘米/秒）的实验有较长的诱导时间与牢固粘附的丝状细菌存在后，细胞外物质的积累。在这两种情况下，丝状细菌成为生物膜的永久部分后，流体摩擦阻力增加。
Fouling biofilm development was monitored in a completely mixed tubular recycle reactor. A unique sampling system allowed direct (brightfield, epifluorescence and scanning electron photomicroscopy) and indirect (increased fluid frictional resistant) observations of biofilms. Low fluid velocity (138.5 cm/s) experiments had shorter induction times and biofilm matrixes which included firmly adherent filamentous bacteria. High fluid velocity (265.4 cm/s) experiments had longer induction times with firmly adherent filamentous bacteria present only after the accumulation of extracellular materials. In both cases the fluid frictional resistance increased after filamentous bacteria became a permanent part of the biofilm.
