“…Hydrogen production is attractive for its high-energy content, 141.9 MJ kg À1 , and it is considered as a promising alternative to fossil fuels, producing water rather than greenhouse gases during its combustion. The 1,3-PD has important applications and it can be used as a solvent, monomers for cyclic compounds, and monomers for condensation to produce plastics [20,21].…”

“…However, the use of pure cultures involves expensive equipment and complicated protocols. In contrast, methods with mixed cultures do not require these procedures, adopted by pure cultures, and they are easy to implement, incurring lower costs and fewer contamination problems [20].…”

This study compared the biohydrogen generation by subtropical mixed and pure cultures from the crude glycerol from the biodiesel production using waste cooking oils (WCO). The crude glycerol was pretreated by pH adjustment. The mixed culture was obtained from a subtropical granular sludge of the UASB (Upflow Anaerobic Sludge Blanket) reactor used in the treatment of vinasse from sugarcane of ethanol and sugar industry. It was heat treated in order to inactivate hydrogen-consuming bacteria, which was identified by Illumina MiSeq Sequencing with a relative abundance of 97.96% Firmicutes Philum, 91.81% Clostridia Class and 91.81% Clostridiales Order. The pure culture was isolated from a subtropical granular sludge from UASB reactor of treating brewery wastewater and identified as Enterobacter sp. (KP893397). Two assays were carried in anaerobic batch reactors in order to verify the hydrogen production from crude glycerol bioconversion with: (I) mixed culture and (II) pure culture. The experiments were conducted at 37 C, initial pH of 5.5 for assay I and 7.0 for assay II, with 20 g COD L À1 of crude glycerol. The crude glycerol consumption was 56.2% and 88.0% for the assay I and II, respectively. The hydrogen yields were 0.80 moL H 2 mol À1 glycerol for the assay I and 0.13 moL H 2 mol À1 glycerol for the assay II. Enterobacter sp. preferred the reductive metabolic route, generating 1460.0 mg L À1 of 1,3-propanediol, and it showed to be more sensitive in the presence of methanol from crude glycerol than mixed culture that preferred the oxidative metabolic route with biohydrogen generation. The mixed culture was more able to generate H 2 than pure culture from the crude glycerol coming from the biodiesel production using WCO.

“…Anaerobic co‐digestion of different organic residues has been widely investigated with a view to enhancing the performance of anaerobic digestion regarding biogas production and total solids reduction . Usually, during a co‐digestion process one main basic feedstock (e.g., animal manure or sewage sludge) is mixed with a smaller amount of a second one (e.g., crop residues, silage, and food wastes) to feed the digester . Only a few studies have examined the co‐digestion of multiple feedstocks (Valenti et al ., unpublished) and demonstrated successful biogas production from multiple organic residues.…”

Biogas obtained from the anaerobic digestion of biomasses has increasingly been considered a feasible alternative to energy production from fossil fuel because of the possible advantages derived from both the reduction of the environmental burden and the reuse of by‐products and agricultural residues. Italy is the third largest biogas producer in the world after China and Germany, but the biogas sector in southern Italy, especially in Sicily, is still developing. The objective of this study was to contribute to the sustainable development of the biogas sector in Sicily by developing a method for the localization of geographical areas suitable for biogas production. First, a feedstock mixture found in previous research studies (which investigated several mixes of main agricultural residues and by‐products available in Sicily for the enhancement of biogas production in terms of methane content) was used to evaluate each feedstock territorial distribution in a study area. Then a GIS‐based model for the computation of a spatial index of feedstock‐mixture availability, ifm_a , was developed. The computed spatial index was applied on a GIS map to investigate the availability of the feedstock mixture in the area under study. The results of the territorial analyses obtained by applying the index showed the geographical areas suitable for the development of new biogas plants. The results of this study could be helpful in reducing the significant transport costs of each feedstock as well as the environmental impact of biogas production. In this regard, the results are in line with the policy priorities of the Europe 2020 strategy, which aims to valorize by‐products and agricultural residues through their reuse. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
