“…An efficient pretreatment process to stabilize the feedstock is necessary before hydrogen and methane fermentation. Various pretreatment strategies for FW prior to anaerobic digestion/fermentation have been reported, namely enzymatic treatment [64], thermal treatment [65,66], acid [67], alkali [68,69], ozone [66], hydrothermal [70], autoclaving [71], bio-electrohydrolysis [72], and ultrasonication [73]. All these pretreatments either lead to hydrolysis of the FW, or enrichment of hydrogen/methane producers and inhibition of the pathogenic bacteria in the FW.…”

“…Phylum proteobacteria have high ability to adapt and could break down large organic compounds into the simple compound. Phylum Firmicutes often plays a role in hydrogen fermentation (Jang et al, 2015). Inoculum source that used in this study had a source of the potential hydrogenproducing bacteria, i.e.…”

The natural microbial consortium from many sources widely used for hydrogen production. Type of substrate and operating conditions applied on the biodigesters of the natural consortium used as inoculum impact the variation of species and number of microbes that induce biogas formation, so this study examined the effect of different inoculum source and its combination of biohydrogen production performance. The hydrogen producing bacteria from fruit waste digester (FW), cow dung digester (CD), and tofu waste digester (TW) enriched under strictly anaerobic conditions at 37OC. Inoculums from 3 different digesters (FW, CD, and TW) and its combination (FW-CD, CD-TW, FW-TW, and FW-CD-TW) were used to test the hydrogen production from melon waste with volatile solids (VS) concentration of 9.65 g/L, 37°C and initial pH 7.05 ± 0.05. The results showed that individual and combined inoculum produced the gas comprising hydrogen and carbon dioxide without any detectable methane. The highest cumulative hydrogen production of 743 mL (yield 207.56 mL/gVS) and 1,132 mL (yield 231.02 mL/gVS) was shown by FW and FW-CD-TW, respectively. Butyric, acetate, formic and propionic were the primary soluble metabolites produced by all the cultures, and the result proves that higher production of propionic acid can decrease hydrogen yield. Clostridium perfringens and Clostridium baratii prominently seen in all single and combination inoculum. Experimental evidence suggests that the inoculum from different biodigesters able to adapt well to the environmental conditions and the new substrate after a combination process as a result of metabolic flexibility derived from the microbial diversity in the community to produce hydrogen. Therefore, inoculum combination could be used as a strategy to improve systems for on-farm energy recovery from animal and plant waste to processing of food and municipal waste.Article History: Received February 5th 2018; Received in revised form May 7th 2018; Accepted June 2nd 2018; Available onlineHow to Cite This Article: Amekan, Y., Wangi, D.S.A.P., Cahyanto, M.N., Sarto and Widada, J.

“…The process has been proven at full scale; the investment cost is one of the lowest among pretreatments . It is applicable to a great variety of substrates (corn stover, pulp and paper sludge, food wastes and high sugar yields) or relatively high gas biofuels yields can be obtained (Table ). However, in some work the presence of phenolic compounds such as coniferylaldheyde has been observed; for instance, after the pretreatment of Norway spruce by Larsson et al 0.2 mmol L −1 of this compound was found after the treatment of biomass by NaOH.…”

The organic fraction of municipal solid waste (OFMSW), mainly composed of lignocellulosic polymers, is extremely complex. Therefore, it is necessary to apply pretreatments to remove the lignin content and decrease the cellulose crystallinity in order to use the OFMSW for gas biofuels production in the context of biorefineries from waste. This work focused on critically reviewing the conventional pretreatments applied to OFMSW, with the goal of improving the H 2 production, as well as other biofuels in modern biorefineries. There are a wide variety of pretreatments that have successfully been used, mainly alkaline, milling and dilute acid. In addition, some research has focused on the recovery and reutilization of the alkali, acid or solvents after the pretreatment, to be incorporated into new cycles of production, minimizing the environmental impacts. Moreover, it would be necessary to incorporate analytical tools, in order to determine the sustainability of the biorefinery project. It is concluded that waste pretreatments could significantly contribute to increased yields of biogas fuels in organic waste-based biorefineries. Therefore, establishing preliminary stages for conditioning biomass or wastes is essential to improve the degradation of wastes and bio-product generation. 938 www.soci.org L Romero-Cedillo et al. db dry basis wb wet basis wrm wet reactor mass J Chem Technol Biotechnol 2017; 92: 937-958 /jctb , [56.76 j , 2.53 k ] 104 J Chem Technol Biotechnol 2017; 92: 937-958 Steam explosion Steam explosion, also known as hydrothermal, promotes the formation of soluble lignin compounds, such as HMF, due to high temperatures that stimulate the breakdown of sugars. 121 In this process, HMF and other inhibitor compounds are generated, such as furans from pentoses and HMF from hexoses. 122 Interestingly, HMF can be finally degraded into levulinic and formic acids. In contrast, even when a pretreatment did not necessarily remove lignin, it was hypothesized that high temperatures had a significant J Chem Technol Biotechnol 2017; 92: 937-958 /jctb J Chem Technol Biotechnol 2017; 92: 937-958
