“…The formation, structure, and biodiversity of a biofilm from a UASB reactor treating brewery wastewater was examined using FISH, DGGE, and cloning. The (Naidoo et al, 2008); anaerobically treated pig waste (Bouity-Voubou et al, 2008); a biofilm reactor for drinking water pretreatment (Zhang et al, 2008c); biofilms involved in microbial fuel cells (Ki et al, 2008); and soil samples (Macdonald et al, 2008). Several mathematical approaches can be used to calculate diversity coefficients, and to quantify the divergence of a community over time.…”
