Mature granules and flocs from aerobic sludge were collected from the wastewater treatment plant (WWTP) treating both municipal and industrial effluents in Haining city China. This plant has been operating under conditions favoring aerobic granular sludge formation, for over 3 years, suggesting that the granules, which stably retained under changing effluent conditions, may contain unique microbial populations. Microbial analysis indicated that the granular sludge was primarily composed of Planctomycetes, Proteobacteria and Bacteroidetes from the bacterial phyla. Interestingly, microbial communities were also observed to be stratified between the structural features of the sludge. For example, Euryarchaeota was found to make up the majority of the archaea found in the granules while Methanosaeta was dominant in the flocs. Additionally, granules were found to contain, 34 phyla and 222 genera of bacteria, 4 phyla and 13 genera of fungi, and 2 phyla and 17 genera of archaea. While flocs contained, 32 phyla and 203 genera of bacteria, 6 phyla and 26 genera of fungi, and 2 phyla and 12 genera of archaea. This biodiversity signifying a preservation of bacterial and archaeal population in granules, and fungal populations in flocs may result from the sedimentary characteristics of the granules. This suggests microbes uniquely associated in the granules are playing a key role in structure formation and stability of the granular ecosystem, which is maintained by the longer sludge retention time.

“…Yang et al have traced the bacteria populations in a full-scale printing and dyeing wastewater treatment system and found that, in spite of variation in the microbial community and composition of the influents, Clostridium sp. could be detected in all the test samples [25]. Fernando et al have developed an anaerobic mixed culture capable of decolorizing a broad-spectrum of azo dyes.…”

An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye. The chemical oxygen demand (COD) removal rate of the dye wastewater reached 52% after 12 h of incubation. Polymerase chain reaction and denaturing gradient gel electrophoresis (PCR-DGGE) profiles revealed that the microbial community changed as a result of varying initial concentrations of dyes. Phylogenetic analysis indicated that microbial populations in the sludge belonged to the phyla Acidobacteria, Firmicutes, Bacteroidetes, Chloroflexi and Proteobacteria. The degradation products of the three types of dye were identified. For azo dyes, the anaerobic sludge converted Methyl Orange to N,N-dimethylbenzene-1,4-diamine and 4-aminobenzenesulfonic acid; for triphenylmethane dyes, after Malachite Green was decolorized, the analyzed products were found to be a mixture of N,N-dimethylbenzenamine, 3-dimethyl-aminophenol and 4-dimethylaminobenzophenone; for anthraquinone dyes, two products (acetophenone and 2-methylbenzoic acid) were observed after Reactive Blue 19 decolorization. Together, these results suggest that the anaerobic sludge has promising potential for use in the treatment of industrial wastewater containing various types of dyes.

“…Nevertheless, these techniques may be not an option when a large number of samples are to be compared and thus community fingerprinting methods may be preferred. DGGE, in spite of its bias and all its limitations, including low coverage (Muyzer et al, 1993;Van Wintzingerode , 1997;Muyzer & Smalla, 1998;Farnleitner et al, 2004), is an adequate method when the aim is to compare patterns along a process or over different sites (Gilbert et al, 2012;Ling et al, 2012;Yang et al, 2012). Although DGGE may also be used to assess phylogenetic diversity, a major drawback is the poor resolution, when different nucleotide sequences co-migrate in a single band, violating the rule one-band-one-organism assumed in this technique (Vallaeys et al, 1997).…”

This study aimed to assess the influence of water treatment and distribution on the bacterial communities with particular emphasis on tap water. Samples from the water treatment plant, the bulk supply distribution system and household taps, supplied by the same drinking water treatment plant, were analyzed using culture-dependent and culture-independent methods. Water treatment imposed alterations in the composition of the bacterial community, although this effect was more evident in the cultivable bacteria rather than among the total community assessed by 16S rRNA gene-denaturing gradient gel electrophoresis (DGGE) profiling. Water disinfection, mainly chlorination, promoted a reduction on bacterial diversity and cultivability, with a shift in the pattern of cultivable bacteria from predominantly Gram-negative to predominately Gram-positive and acid-fast. Downstream of the chlorination stages, tap water, in comparison with raw water, presented higher diversity indices and cultivability percentages. From the source to the tap, members of the Alpha-, Beta- and Gammaproteobacteria were the predominant lineages identified using 16S rRNA gene-DGGE analysis. Although with a lower coverage, the DGGE-based lineage identifications were in agreement with those found using 454-pyrosequencing analysis. Despite the effectiveness of water treatment to eliminate or inactivate most of the bacteria, Proteobacteria such as Acinetobacter, Bosea and Sphingomonadaceae may successfully colonize tap water.
