“…The production of biogas (∼ 5000 Nm 3 d −1 , CH 4 60-61%) was lower than the theoretical one (estimated using Buswell equation as reported previously 37 ) during the survey but did not vary >5%. The proportion of the PML in the feedstock mixture was incremented from 1.6% to 7.5%, corresponding to a decrease of the C:N ratio in the feedstock mixture from 14.2 to 11.4 ( Fig.…”

BACKGROUND This study assessed the composition and dynamics of the bacterial and archaeal communities in a full‐scale two‐stage anaerobic digester over five months. The plant was fed on a variable mixture of feedstock, in which the energy crops were replaced with poultry manure/litter (from 1.6% to 7.5%) to reduce the operational costs. RESULTS The elevated concentration of ammonia in the digester did not hamper biogas production and its concentration of methane. The low level of acetate, butyrate and propionate in the methanogenesis phase indicated a strong activity of acetotrophic methanogens. PCR‐DGGE and sequencing have demonstrated that the stability of the volatile fatty acid distribution concurred with low level of population shifts as shown by the moving windows analysis. Nevertheless, PCoA analyses revealed that the variation in the digester alimentation and the carbon:nitrogen (C:N) ratio had a key role in assembly the bacterial and archaeal communities. The high ammonia level favoured the growth of Caldicoprobacteraceae and Syntrophomonadaceae, whereas dominant archaea detected belonged to the family of Methanosarcinaceae. CONCLUSION Cheap and readily available N‐rich feedstock could be used safely to decrease the costs of the anaerobic digestion process. © 2019 Society of Chemical Industry

“…These groups may be regarded in the genomics approach as a prospective useful tool for the determination and subsequent manipulation of appropriate species and an additional marker in models for the prediction of potential biogas yields. Achinas and Euverink (2016) or Demirel and Scherer (2008) also suggest that these microorganisms are important marker groups in methanogenesis.…”

The goal was to elucidate the importance of the waste properties for effective exploitation in biogas production and for soil application, respectively, based on the physicochemical and microbial characterization of biowaste and the corresponding biogas residues. The following waste media were chosen: fruit waste, dairy sewage sludge, corn silage, grass silage, and grain brew to prepare three co-substrates for anaerobic bioconversion. The most satisfactory biogas yield was obtained from biowaste with the following composition: 25% fruit wastes, 25% dairy sewage sludge, 12% corn silage, and 38% grain brew. The study included functional and genetic diversity assessment through the characterization of the catabolic potential and structure of the microbial communities inhabiting the examined organic wastes and their relative biogas residues. The metabolome was based on the use of a Biolog ® plate. The elucidation of the metagenome employed the genetic structure of prokaryotes and involved denaturing gradient gel electrophoresis and next-generation sequencing analyses. The usefulness of metagenomics was emphasized by ecotoxicological evaluation of biowaste and in determining the accurate start-up community composition for biogas production, highlighting the pivotal role of anammox and hydrolytic bacteria as marker groups. The high importance of the great diversity of fungi was also revealed based on a functional approach.

“…Theoretical biochemical methane potential of the material, TBMP (mL/g VS), can be estimated using eqs. 1 and 2 [22][23][24][25][26][27][28], where V m =22.4 L/mol represents the molar volume of the gas under standard conditions, (g/mol) the molar mass of biomass (given by eq. 3), and M i (g/mol) the molar mass of element i (C, H, O, N, and S).…”

“…According to eqs. 2 and 3, the values of and TBMP determined depending on tabulated levels of subscripts, i.e., a=36.51, b=64.03, c=32.53, and d=1, were 1037.53 g/mol and 383 mL/g VS. TBMP is an important parameter for providing essential information before developing biogas projects at industrial scale, allowing comparison between different feedstocks [22].

Anaerobic digestion of organic matter with high moisture content has proven to be a suitable method for disposal of wet organic residuals with several advantages compared to other treatment technologies. This paper aimed at evaluating the theoretical and experimental biomethane potential of food processing residuals that are responsible for negative environmental impact, with exemplification for the potato processing waste. The biomethane potential is a useful parameter to assess the economic efficiency of anaerobic digestion processes as it can considerably influence the efficiency and the economic feasibility of the energy recovery technologies. Both experimental and theoretical biomethane potentials of potato waste in mesophilic anaerobic digestion as well as biodegradability of the substrate were estimated. Moreover, effects of microalgal extract addition on the digestion of potato waste were examined in an attempt to stimulate the anaerobic digestion. Cone model and a modified Gompertz model were used to predict the dynamics of biomethane production.
