“…12 The study of Alibardi and Cossu indicated that the bread-pasta fraction in organic wastes has a marked effect on hydrogen potential production. 13 Ren et al presented a comprehensive review on the bioconversion of lignocellulosic biomass to hydrogen, which sheds light on the perspectives on lignocellulosic biomass conversion to hydrogen.…”

“…In other words, the co-cultured strains underwent the ethanol-type fermentation researched by Ren et al 32 The high content of ethanol in the end liquid products could buffer the ferment-end pH and reduce the inhibition of end products from MCC, which is benecial for maintaining the stability of microbial growth and hydrogen formation. 13,33 Hence, the effect of substrate concentration on biohydrogen production should be revealed. As shown in Fig.…”

Optimization of key factors affecting biohydrogen production from microcrystalline cellulose by the co-culture of Clostridium acetobutylicum X₉ + Ethanoigenens harbinense B₂

The key factors (initial pH value, substrate concentration, incubation time, C/N and L-cysteine concentration) that affect biohydrogen production from microcrystalline cellulose in batch fermentation by the co-culture of isolated strains (Clostridium acetobutylicum X 9 + Ethanoigenens harbinense B 2 ) were optimized using an orthogonal experiment. The isolated strain, Clostridium acetobutylicum X 9 , had high hydrogen yield from microcrystalline cellulose (MCC), and Ethanoigenens harbinense B 2 could produce hydrogen efficiently from monosaccharides directly from microcrystalline cellulose. The optimal parameters were as follows: initial pH value of 6.0, 12 g L À1 substrateconcentration, 40 h incubation time, 0.7 g L À1 L-cysteine concentration and a 4 : 1 ratio of C/N. Under the optimum culture conditions, a maximum hydrogen yield rate of 10.4 mmol g-MCC À1 was obtained.This yield is approximately 2.2-fold greater than that of mono-culture Clostridium acetobutylicum X 9 . It suggests that the optimal conditions achieved can be applied to the production of hydrogen from microcrystalline cellulose using the co-culture of isolated strains, Clostridium acetobutylicum X 9 + Ethanoigenens harbinense B 2 .

“…Together with OWHB, the municipal solid waste (MSW) includes trash and garbage from the daily life of people. MSW has a significant organic fraction [2] and a variable composition depending on the place and time of the year [12]. In addition, OW comes from breed animals, e.g., cattle, pigs, etc., in the form of animal manure (AM) [13,14].…”

Biogas Micro-Production from Human Organic Waste—A Research Proposal

et al. 2018

Organic waste (OW) management tackles the problem of sanitation and hygiene in developing countries and humanitarian camps where unmanaged waste often causes severe health problems and premature death. OW still has a usable energy content, allowing biogas production, potentially contributing to satisfy the local needs, e.g., cooking, lighting and heating. Digesters are the devices converting OW into biogas under anaerobic conditions. They are simple and effective solutions for the OW management in rural areas, humanitarian camps and remote developing regions, producing energy and fertilizers for local farming as residual. This paper describes the design and lab-test of a domestic OW management system integrating a waterless toilet with a small-scale digester producing safe biogas for local micro-consumption. Starting from people's needs and an extensive review of the current state-of-art technology, the proposed system's key innovation and strength is the combination of effectiveness and a very simple construction, set up and use, fitting with the rural conditions and raw materials available within the emerging countries. A small-scale prototype is assembled and lab-tested assessing the quantity-i.e., productivity-and quality-i.e., composition and methane content-of the produced biogas. The measured productivity in terms of specific biogas production (SBP) is of about 0.15 m 3 /kg SV and a methane content of about 74% in mass match the energy needs of domestic users, encouraging the spread of such systems in developing regions and rural areas.

“…Their comprehensive literature review revealed only studies from full-scale wastewater treatment plants performing co-digestion with the organic fraction of municipal solid waste (OFMSW), fruit and vegetable waste (FVW) as well as used cooking oil, while no studies were found focusing on co-digestion of food waste (Mata-Alvarez et al, 2014). This might be attributed to the fact that the term food waste is not very clear defined, hampering the comparability of different studies (Alibardi and Cossu, 2015). This paper is filling the lack of experiences reported from full-scale digester facilities treating food waste as co-substrate.…”
