“…In contrast, Firmicutes initially predominated in pig and chicken manure composts and increased in their relative abundance during composting. This could be explained by ability to form endospores that can help Firmicutes to survive high temperatures and harsh environment, which has also been shown in previous studies (Hartmann et al, 2014;Bello et al, 2020). At the genera level, bacterial community profiles in pig and chicken manure composts differed initially but converged toward the final phase of composting.…”

“…Livestock manures is one the common raw materials used in composting and microbial communities of livestock and poultry manures have been explored extensively during composting (Awasthi et al, 2019;Chen et al, 2019;Bello et al, 2020). It has been established that different composting systems using manure from different animals are associated with specific microbiota.…”

Livestock Manure Type Affects Microbial Community Composition and Assembly During Composting

Composting is an environmentally friendly way to turn plant and animal wastes into organic fertilizers. However, it is unclear to what extent the source of animal waste products (such as manure) affects the physicochemical and microbiological properties of compost. Here, we experimentally tested how the type of livestock manure of herbivores (sheep and cattle) and omnivores (pig and chicken) influences the bacterial and fungal communities and physicochemical properties of compost. Higher pH, NO3-N, Total carbon (TC) content and C/N were found in sheep and cattle manure composts, while higher EC, NH4-N, Total nitrogen (TN) and total phosphorus (TP) content were measured in pig and chicken manure composts. Paired clustering between herbivore and omnivore manure compost metataxonomy composition was also observed at both initial and final phases of composting. Despite this clear clustering, all communities changed drastically during the composting leading to reduced bacterial and fungal diversity and large shifts in community composition and species dominance. While Proteobacteria and Chloroflexi were the major phyla in sheep and cattle manure composts, Firmicutes dominated in pig and chicken manure composts. Together, our results indicate that feeding habits of livestock can determine the biochemical and biological properties of manures, having predictable effects on microbial community composition and assembly during composting. Manure metataxonomy profiles could thus potentially be used to steer and manage composting processes.

“…Since our samples have been amended with GWS amendment that contains 30% sludge, the development of the Proteobacteria might have been negatively influenced by the type of substrate added. Furthermore, Bello et al (2020) [34] reported a negative correlation between Proteobacteria abundance and N content. Since the GWS amendment increases the N content in soil [24,31], this might be another reason for the Proteobacteria relative abundance decrease in soil that received fresh GWS amendment.…”

Soil amendments with organic waste products (OWPs) have been widely supported in Europe to improve soil fertility, causing wide changes in the microbial community structure and diversity, especially in the short-term period. Those changes are known to affect the volatile organic compound (VOC) emissions by soil. This work aimed to characterize, in terms of quantity and composition, the effect of green waste and sludge (GWS) application on soil VOC emissions and microbial community 49 h after the last GWS application. Two different soil samples were compared to test the effect of the soil history on VOC emissions and microbial communities. For this reason, we chose a soil that received GWS input for 20 years (GWS sample) and one that did not receive any organic input during the same period (CN sample). Furthermore, samples were manipulated to generate three microbial dilution diversity gradients (low, medium, and high). Results showed that Bacteroidetes phyla took advantage of the GWS application in all samples, increasing their relative abundance by 22% after 49 h, while the Proteobacteria phylum was penalized by the GWS amendment, passing from 58% to 49% relative abundance 49 h after the GWS application. Microbial structure differences between microbial diversity dilution levels remained even after the GWS application. GWS amendment induced a change in the emitted VOC profiles, especially in samples used to receiving GWS. GWS amendment doubled the VOC emissions from samples used to receiving GWS after 49 h. Finally, the microbial community was strongly correlated to the VOC emissions. Firmicutes, Proteobacteria, Actinobacteria, and Crenarchaeota were positively correlated (Pearson coefficient > 0.6), while other phyla, such as Bacteroidetes and Verrucomicrobia, were found to be negatively correlated (Pearson coefficient < −0.6) to the VOC emissions. After the addition of GWS, these correlations shifted from positive to negative and from negative to positive.

“…However, amino acid metabolism experienced a signi cant decline during the rst week of composting and then increased in the cooling phase and mature phase. Amino acid metabolism is known to enhance microbial growth and activity since amino acids can serve as sources of both carbon and energy for microbes during composting (Bello et al, 2020). Therefore, the energy production and conversion subsystem were further analysed by PICRUSt based on the KEGG database (Fig.…”

“…The major components of organic wastes include carbohydrates, including cellulose, proteins, lipids and lignin, and the biodegradation process of organic wastes is carried out by mesophilic and thermophilic microorganisms in sequence (Duan et al, 2019;Xu et al, 2019). The composting products can be further utilized to improve the physical properties of soil (Bello et al, 2020;Esmaeili et al, 2020;Guo et al, 2019). Dissolved organic matters (DOM), as the direct material and energy resource for microorganisms, re ect compost stability and maturity (Said-Pullicino et al, 2007).…”

Co-composting of recycled cow manure and waste bedding material has been used to convert both agricultural wastes to biofertilizers. This study explored the succession of microbial community, metabolic function and substances conversion capacities during 60 days’ co-composting using high throughput sequencing technology. The study revealed that co-composting of cow manure and bedding material waste at a ratio of 1.32 (CM+B) had the highest efficiency among four treatments. The bacterial and fungal community diversity changed significantly during the co-composting of CM+B group, and the major phyla included Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria and Ascomycota. PICRUSt and FUNGuild analysis showed that carbohydrate, lipid metabolism and especially nitrogen fixation were enhanced in the thermophilic phase, while animal and plant pathogens were not detected after the co-composting. Wood saprotrophs became the dominant fungal group (89.1%) in the maturation phase. Canonical correlation analysis (CCA) and redundancy analysis (RDA) confirmed that temperature influenced bacterial community succession more than it influenced fungal community succession. Ruminiclostridium had a significantly positive relationship with temperature (p_value < 0.05), while pH and C/N had significant effect on the fungal (p_value < 0.05), and Penicillium and Mortierella were significantly related to moisture (p_value < 0.05). This work describes an efficient methodology to deal with co-composting systems that had been successfully applied in agricultural wastes treatment, enabling further understanding in mechanisms underlying the substance conversion and the involved microbial community succession in sophisticated composting system.
