“…A thorough understanding and characterization of the microbial communities that participate during composting could lead to improvements in terms of process reproducibility, performance and quality of the end product (Finstein & Morris, ; Lens et al ., ). In addition, monitoring the microbial diversity of the finished compost product is important to evaluate its safety for human use and predict its best application on soil (Anastasi et al ., ).…”

Fungi are known to have an important role in the composting process as degraders of recalcitrant materials such as cellulose and lignin. Previous attempts to study the diversity and succession of fungi in compost systems have relied on the use of culture-dependent analyses and low-resolution DNA-fingerprinting techniques, lacking the necessary depth to analyse such a rich ecosystem. In this study, 454 pyrosequencing was used to characterize the fungal community composition at the different stages of an in-vessel composting process. A complex succession of fungi was revealed, with 251 fungal OTUs identified throughout the monitoring period. The Ascomycota were the dominant phylum (82.5% of all sequences recovered), followed by the Basidiomycota (10.4%) and the subphylum Mucoromycotina (4.9%). In the starting materials and early stages of the process, yeast species from the Saccharomycetales were abundant, while in latter stages and in the high temperature regions of the pile, fungi from the orders Eurotiales, Sordariales, Mucorales, Agaricales and Microascales were the most prominent. This study provides an improved understanding of the fungal diversity occurring during the composting of municipal solid waste, and this knowledge can lead to the development of more efficient composting practices and a better evaluation of the end-product quality.

“…Municipal wastewater treatment is a core requirement of urban populations and results in generation of large amounts of sewage sludge where wastewater pollutants such as organic matter, nutrients, heavy metals, and pathogens are collected and concentrated. Sewage sludge management is a major issue since up to one-half of the costs of operating municipal waste water treatment plants are associated with sludge treatment and disposal (Lens, 2004).…”

There is a growing trend to consider organic wastes as potential sources of renewable energy and value-add products. Fermentation products have emerged as attractive value-add option due to relative easy production and broad application range. However, pre-fermentation and extraction of soluble products may impact down-stream treatment processes, particularly energy recovery by anaerobic digestion. This paper investigates primary sludge pre-fermentation at different temperatures (20, 37, 55, and 70°C), treatment times (12, 24, 48, and 72h), and oxygen availability (semi-aerobic, anaerobic); and its impact on anaerobic digestion. Pre-fermentation at 20 and 37°C succeeded for VFA production with acetate and propionate being major products. Pre-fermentation at 37, 55, and 70°C resulted in higher solubilisation yield but it reduced sludge methane potential by 20%. Under semi-aerobic conditions, pre-fermentation allowed both VFA recovery (43gCODVFAkg(-1)VS) and improved methane potential. The latter phenomenon was linked to fungi that colonised the sludge top layer during pre-fermentation.

“…It contains a high concentration of nitrogen, phosphorus, trace elements, ammonia acid, organic acid, humic acid and auxin [2], which can be processed for use in foliar fertilizer, animal feed and culture solution [3]. The use of membrane technology as a potential method for condensing anaerobic-digested streams to produce foliar fertilizer has been recently developed [4].…”

an air stripping-microalgae cultivation system was proposed to recover nitrogen and produce biomass from biogas fertilizer production wastewater. air stripping was firstly used for reducing the nitrogen to low levels. Then microalgae were used for absorbing the residual nitrogen. Results showed that the nitrogen removal reached 95.0%, with a microalgae productivity and biomass yield of 0.21 (g/L/d) and 4.29 (g-biomass/g-nitrogen), respectively. For the system, 87.7% of the total nitrogen was recycled, from which 83.9% came from air stripping and 3.8% from microalgae absorption. This system enables carbon-emission reduction, wastewater treatment and the promotion of nitrogen recovery.
