“…Our results are therefore consistent with these findings. Gammaproteobacteria was also detected at abundant levels deep in a Japanese landfill (Sawamura et al 2010), in aged refuse from Shanghai landfills , and in our study, demonstrating its important ecological function. We have also provided the first report of the predominance of the phyla Fusobacteria and Tenericutes in landfills.…”

Little is known about the bacterial diversity of landfills and how environmental factors impact the diversity. In this study, PCR-based 454 pyrosequencing was used to investigate the bacterial communities of ten landfill leachate samples from five landfill sites in China. A total of 137 K useable sequences from the V3-V6 regions of the 16S rRNA gene were retrieved from 205 K reads. These sequences revealed the presence of a large number of operational taxonomic units (OTUs) in the landfills (709-1599 OTUs per sample). The most predominant bacterial representatives in the landfills investigated, regardless of geographic area, included Gammaproteobacteria, Firmicutes, and Bacteroidetes. The phyla Fusobacteria and Tenericutes were also found for the first time to be predominant in the landfills. The phylum Fusobacteria predominated (51.5 and 48.8%) in two semi-arid landfills, and the phylum Tenericutes dominated (30.6%) at one humid, subtropical landfill. Further, a large number of Pseudomonas was detected in most samples, comprising the dominant group and accounting for 40.9 to 92.4% of the total abundance. Principal component analysis (PCA) and cluster analysis based on OTU abundance showed that the abundant taxa separated the bacterial community. Canonical correlation analysis (CCA) suggested that precipitation and landfilling age significantly impact on the bacterial community structure. The bacterial community function (e.g., cellulolytic bacteria, sulfate-reducing bacteria (SRB), sulfate-oxidizing bacteria, and xenobiotic organic compound (XOC)-degrading bacteria) was also diverse, but the pattern is unclear.

“…As alternativas propostas em substituição aos aterros sanitários vêm sendo estudadas e discutidas há muitos anos, mas até hoje não se encontrou opção que apresentasse melhor relação custo-benefício (MANFREDI; TONI-NI;CHRISTENSEN, 2010;SAWAMURA et al, 2010;MAN-FREDI;CHRISTENSEN, 2011;SANG et al, 2012).…”

“…Clostridium, Sporanaerobacter, Thermacetogenium, Leuconostoc, Bacillus and Lactobacillus, Pseudomonas, Listonella, Rhodospirillum, Thiomicrospira, Providentia, Klebsiella, Schineria, Escherichia, Enterobacter, Empedobacter, and Flavobacterium were found to be predominant in anaerobic LBRs. Genera that are capable of degrading various substrates, such as Pseudomonas, are present in large numbers in LBRs (1,2,15,28). Flavobacterium and Rhodospirillum degrade mostly proteins and are expected to be present in proteinaceous wastes (28).…”

“…Flavobacterium and Rhodospirillum degrade mostly proteins and are expected to be present in proteinaceous wastes (28). Clostridium and Bacillus can degrade amino acids, fatty acids and sugars (1,2,28,41,42). Clostridium species are strictly anaerobic and typical H 2 -producing bacteria.…”

“…Landfill use is the most common method for their disposal at present. In some countries such as Japan, Taiwan and Switzerland, solid wastes are classified and buried into landfills after incineration (1,2). By contrast, in most countries including Asian developing countries, unclassified solid wastes containing high organic fractions are buried directly in landfills (3,4).…”
