“…In a recent study of the succession of bacterial community function during cow manure composting, Wang et al (in Press) found that the AWCD of carboxylic acids and amino acids in Biolog EcoPlates TM displayed a steady downtrend along the composting process. In a similar way, a significant change in bacterial DGGE pattern was detected during garbage composting (Takaku et al, 2006). Gomez et al (2006) found higher values of AWCD, richness and H ′ diversity from Biolog EcoPlates TM in soil amended with household solid waste compost, horse, and rabbit manure, and chicken manure, compared to unamended soil.…”

“…The high abundance and diversity of Proteobacteria was expected because this phylotype contains mainly chemo-organotrophs, which derive their energy from decomposition and oxidation of organic matter. The observation that Proteobacteria were most dominant during composting is consistent with composting studies elsewhere (Ntougias et al, 2006;Takaku et al, 2006;Danon et al, 2008;Vivas et al, 2009). However, the current results differ from the some previous studies by having α-proteobacteria as the most abundant class.…”

“…Temperatures are usually high in the tropics, which increases evaporation of moisture from compost when it is not covered. Proteobacteria, Bacteroidetes, Firmicutes, Actinobacteria and Planctomycetes which were the dominant phyla have been reported in other composting studies (Takaku et al, 2006;Danon et al, 2008;Székely et al, 2008;Vivas et al, 2009;Neher et al 2013;Karadag et al, 2013;Song et al, 2014;Manyl-loh et al. 2016).…”

“…However, the current results differ from the some previous studies by having α-proteobacteria as the most abundant class. Takaku et al (2006) and Vivas et al (2009) reported β-proteobacteria while Ntougias et al (2006) observed γ-proteobacteria as the dominating classes in the composting process. The reason for this disparity is not clear but it may be attributed to differences in locality, composting substrate and methods used.…”

“…Although, there have been studies on bacteria community in composting elsewhere, few of these studies have traced and described the microbial community during an entire composting process. For example, Takaku et al (2006) used DGGE and PCR amplified 16S rDNA to study microbial community during composting of food garbage and rice hulls in Japan. Results showed change in microbial community between composting stages.…”

Bacterial communities are actively involved in composting process but the environment within the compost influences their diversity, abundance and succession. In this study, the authors investigated the bacterial communities in tropical crop waste compost using pyrosequencing. Municipal crop wastes from the tropics (Uganda) were composted under four different low-technology methods. Samples were collected from the early thermophilic, late thermophilic, and mesophilic phases, and from mature compost. Pyrosequencing of the amplified variable V4 region of the 16s rDNA generated over 110 000 sequences. Chao1 and cluster analysis at 3% dissimilarity showed that bacterial community richness declined during the composting process. The community was dominated by a few bacterial taxa during the thermophilic phases. Species evenness increased as compost progressed to maturity despite a decline in the number of taxa over the successional progression. Bacterial community diversity, abundance and succession changed with the composting method. This pattern of diversity may be attributed to competition and selection during the microbial succession. A total of 22 phyla and 513 genera were identified from all the methods in the entire composting process. The most abundant phyla were Proteobacteria, Firmicutes, Bacteriodes and Actinobacteria. Pyrosequencing provided more information on compost bacterial community diversity and abundance than previously used molecular methods. Several novel bacteria existing in tropical crop waste compost remained unclassified.

Molecular ecological techniques for direct identification of microbes involved in PLA degradation under aerobic composting conditions are described. Gene sequences from genera Paecilomyces, Thermomonospora, and Thermopolyspora were most abundant in the compost samples. Members of these phylogenetic lineages are therefore likely to play an important role in PLA degradation. The use of molecular ecological techniques to design cultivation strategies may also provide a new tool for identification and investigation of biodegradation mechanisms and for future development of efficient biological treatment or recycling processes for PLA and other biodegradable polymers.
