“…Both the bacterial and archaeal community structure was influenced by the co-digestion of different proportions of substrates [37]. Furthermore, it was also reported that archaeal communities would be altered by bacterial populations [26].…”

The effects of chemical composition (carbohydrates, lipids, and protein) on the anaerobic co-digestion performance of food wastes (FW) were investigated from the viewpoints of methane production, dynamic parameters, and microbial community structure. The results of this study showed that a notable gasification rate was positively correlated with the proportion of the composition. A T2 reactor, which consisted of 60% carbohydrates, 20% lipids, and 20% protein, held a higher gasification rate of 65.09% compared to other groups, while its process parameters showed some deficiency regarding the stability of digestion, especially for low biochemical methane potential (BMP), which was not beneficial for the actual practice. A T4 reactor, with a highest gasification rate of 70.68%, held the maximum BMP (497.44 mL/g VS). The stable chemical parameters achieved the optimal proportion, consisting of 40% carbohydrates, 40% lipids, and 20% protein. Furthermore, its microbial populations were rich and achieved a balance of the two main dominant communities of acetoclastic methanogens and hydrogenotrophic methanogens, whose relative abundance was close. It was obvious that interactive effects were caused by different proportional composition, which led to constantly changing chemical parameters and microbial community.

“…The similar kind of results were noticed in the study conducted by Sinha and Bharambe (2008) where, they have conducted an experiment and recorded chemical oxygen demand as 112, 128, and 132 g l -1 in different treatments. In the present study COD content in the horticultural waste was higher when compared to the results of Jimenez et al (2015) who studied that A new organic matter fractionation methodology for organic wastes: bio accessibility and complexity characterization for treatment optimization and recorded the COD (56.90, 79.50 and 98.20 g l -1 ) in the digested sludge of agricultural waste in different treatments.…”

Agriculture, apart from crops and livestock, is a source of large amounts of troublesome by like different kinds of manure. Nevertheless, they could be successfully processed through anaerobic digestion technology, which allows for waste utilization and energy generation. Production of biogas from manure only is low efficient due to the low dry matter content (about 8%). The additional substrates, such as plants with high dry mass content, are used to improve the process efficiency. In this work biogas production technologies from different agricultural as well as horticultural feedstock was used along with the pretreatment w cellulose degrading bacteria, a comparative experimental analysis between different types of biomass residues used for biogas production estimation of biological oxygen demand chemical oxygen demand (COD), cellulose, pH, Nitrogen, Phosphorus and Potassium anaerobic fermentation process. The comparison is achieved using as parameter the biogas quality and quantity which are produced, using different available agricultural and horticultural waste material. measurements were made on a lab scale pilot installation.

“…Moreover, signals related to cellulose and amino-acids were removed from the solid residue of substrate after the PEOM extraction.Furthermore, comparison of the amount of C extracted during the sequential extraction procedure and total C content of the samples demonstrated that more than 60% of the total initial C was still retained in both the substrate and digestate samples after sequential extraction. Nevertheless, the structural characterization of OM in our study revealed that NEOM, representing the fraction with low degree of bio-accessibility(Jimenez et al, 2015), comprised mainly of aliphatic and aromatic CH groups of the protein/biomass fraction of the OM.The major organic molecules targeted by the chemical reagents used for fractionation of particulate OM according toJimenez et al (2017Jimenez et al ( , 2015Jimenez et al ( , 2014 and the findings of this study are summarized in…”

“…Jimenez et al (2017Jimenez et al ( , 2015Jimenez et al ( , 2014 identified the nature of the organic molecules in the liquid fractions extracted by the fractionation procedure. Similarities are only found in SEOM and PEOM fractions, whereas the organic molecules found in NEOM fraction reflects the nature of substrate analyzed.…”

This study evaluates a simultaneous assessment of organic matter (OM) and trace elements (TE) bio-accessibility in substrate and digestate from a full-scale anaerobic digester by a sequential OM extraction method. Simultaneous release of TE was determined along with the extraction of different OM fractions and the effects of extracting reagents on characteristics of OM were evaluated by nuclear magnetic resonance (NMR) spectroscopy. The reagents used for sequential extraction of OM were not enough selective. However, proteins were particularly removed by 0.1 M NaOH, while 72% H2SO4 mainly extracted hemicellulose and cellulose. The OM fractionation allowed for simultaneous extraction of >60% of total As, Cd, Co, Fe, Mn, Ni and Zn, while the extraction efficiency was limited for Al, Cr, Cu, Mo, and Pb. In substrate, >50% of total As, Co, Mn and Ni and <40% of total Fe, Zn and Mo were identified in bio-accessible fractions. In digestate, all elements demonstrated poor bio-accessibility except for As.
