“…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).…”

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.

“…Firmicutes have been reported during different stages of composting (Ntougias et al, 2006;Takaku et al, 2006;Karadag et al, 2013) and were favored by alkaline medium. Therefore, increase in abundance of Bacillus and Clostridia could be attributed to favorable alkaline pH during the composting.…”

“…The number of loosening in the process of composting is from 2 to 6 times [11]. Aeration is performed by periodic loosening of a compost mixture by movable technical means or by feeding air into the substrate by the ventilation equipment under stationary conditions [4,5]. When forming and aerating the clamps, the processes of motion of the raw materials in plane and space are considered [1,10].…”

“…At subsequent aeration, carbon oxide is released while the raw materials are oxyge nated [11,12]. Although articles [7][8][9][10] address the influence of the shape of a clamp and appropriate aeration [4,5,11] on the compost formation process, but the parameters of machines that can perform the required technological operations are not sufficiently formalized.…”

During composting, the composition of microbial communities is subject to constant change owing to interactions with fluctuating physicochemical parameters. This study explored the changes in bacterial and fungal communities during cattle farm waste composting and aimed to identify and prioritize the contributing physicochemical factors. Microbial community compositions were determined by high‐throughput sequencing. While the predominant phyla in the bacterial and fungal communities were largely consistent during the composting, differences in relative abundances were observed. Bacterial and fungal community diversity and relative abundance varied significantly, and inversely, over time. Relationships between physicochemical factors and microbial community compositions were evaluated by redundancy analysis. The variation in bacterial community composition was significantly related to water‐soluble organic carbon (WSOC), and pile temperature and moisture (p < .05), while the largest portions of variation in fungal community composition were explained by pile temperature, WSOC, and C/N (p < .05). These findings indicated that those parameters are the most likely ones to influence, or be influenced by the bacterial and fungal communities. Variation partitioning analyses indicated that WSOC and pile temperature had predominant effects on bacterial and fungal community composition, respectively. Our findings will be useful for improving the quality of cattle farm waste composts.
