摘要：
The existing relationships were studied among the different types of filamentous microorganisms that appear in the biofilm of a biological contactor system. Using the hierarchical cluster analysis it was observed that, in all the stages, Beggiatoa sp. and the Eikelboom's types 0803 and 1863 always appeared associated, while Sphaerotilus natans was always associated with the morphological type 021N. The remaining microorganisms were associated in variable forms in the plants. In addition, different association models were obtained according to the season of the year and the stage-season interaction. It has also been observed that a significant correlation exists among the filamentous microorganisms we have studied and the different physical-chemical parameters. © 2007 Association of Microbiologists of India.
