    Abstract: This study investigated the impact of composting substrate types on the bacterial community structure and dynamics during composting processes. To this end, pig manure ( PM ), chicken manure ( CM ), a mixture of PM and CM ( PM  +  CM ), and a mixture of PM , CM and anaerobic digestion residue ( ADR ) ( PM  +  CM  +  ADR ) were selected for thermophilic composting. The bacterial community structure and dynamics during the composting process were detected and analysed by polymerase chain reaction–denaturing gradient gel electrophoresis ( DGGE ) coupled with a statistic analysis. The physical‐chemical analyses indicated that compared to single‐material composting ( PM , CM ), co‐composting ( PM  +  CM , PM  +  CM  +  ADR ) could promote the degradation of organic matter and strengthen the ability of conserving nitrogen. A DGGE profile and statistical analysis demonstrated that co‐composting, especially PM  +  CM  +  ADR , could improve the bacterial community structure and functional diversity, even in the thermophilic stage. Therefore, co‐composting could weaken the screening effect of high temperature on bacterial communities. Dominant sequencing analyses indicated a dramatic shift in the dominant bacterial communities from single‐material composting to co‐composting. Notably, compared with PM , PM  +  CM increased the quantity of xylan‐degrading bacteria and reduced the quantity of human pathogens.

    Metaproteomics reveals major microbial players and their biodegradation functions in a large‐scale aerobic composting plant

    Abstract: Composting is an appropriate management alternative for municipal solid waste; however, our knowledge about the microbial regulation of this process is still scare. We employed metaproteomics to elucidate the main biodegradation pathways in municipal solid waste composting system across the main phases in a large‐scale composting plant. The investigation of microbial succession revealed that Bacillales, Actinobacteria and Saccharomyces increased significantly with respect to abundance in composting process. The key microbiologic population for cellulose degradation in different composting stages was different. Fungi were found to be the main producers of cellulase in earlier phase. However, the cellulolytic fungal communities were gradually replaced by a purely bacterial one in active phase, which did not support the concept that the thermophilic fungi are active through the thermophilic phase. The effective decomposition of cellulose required the synergy between bacteria and fungi in the curing phase.

    Effect of inoculation with a microbial consortium that degrades organic acids on the composting efficiency of food waste

    Abstract: In order to overcome the excessive acidification problem, a microbial consortium for the degradation of organic acids ( MCDOA ), which acts synergistically in degrading organic acids, was developed and used as an inoculum to improve the efficiency of food waste composting. MCDOA could eliminate the initial lag phase of the pile temperature rise because of excessive acidification and effectively shorten the composting period. Fluorescence regional integration analysis of the excitation‐emission matrix spectra of dissolved organic matter showed that compared with raw material, in compost with MCDOA inoculation, the percent fluorescence response ( P i,n ) values of Regions I, II and IV decreased by 95.11%, 94.19% and 87.41%, respectively, and P i,n of Region V increased by 172.57%. The decreased and increased levels were markedly higher than in the two control groups (MgO and K 2 HPO 4 treatment, and uninoculated compost). These findings revealed that MCDOA accelerated the degradation of proteinaceous compounds and the formation of complicated humic‐like materials. Bacterial profiles implied that MCDOA could improve the indigenous bacterial community structure and diversities of acetic and propionic acid‐degrading and lignin‐degrading bacteria, which might account for the high composting efficiency and degree of humification of the inoculated compost.

    Effect of inoculation with multiple composite microorganisms on characteristics of humic fractions and bacterial community structure during biogas residue and livestock manure co‐composting

    Abstract: It is necessary to inoculate microbes in the composting of special materials. Biogas residue ( BR ) is rich in refractory lignocellulose. To improve humification processes of BR composting, composite microorganisms ( CMs ), with multiple functions, were added to the mixture of BR and animal manure. RESULTS The results indicated that four humification indices ( DP , PHA , HR , HI ) were all markedly higher in the inoculated compost (0.46, 27.5, 43.34, 11.92) than in the uninoculated compost (0.39, 22.53, 28.56, 6.49) ( P   〈  0.05). The inoculation increased the degree of polycondensation and aromatization, and molecular size, as well as the humification degree of BR compost as determined by fluorescence spectroscopy and fluorescence regional integration analysis of humic acids, fulvic acids and hydrophilic fraction, three chemically isolated fractions. Additionally, the inoculation increased the quantity and diversity of indigenous microorganisms and accelerated their proliferation by adjusting environmental conditions to optimize their growth. CONCLUSION The CMs inoculant is suitable for BR composting and inoculating based on the composition of the composting substrate could enhance composting efficiency and improve compost quality. © 2014 Society of Chemical Industry
