“…The accumulation of this metabolite is usually observed in systems operated with low hydraulic retention times and could be associated with the consumption of acetic and propionic acids (ANTONOPOULOU et al, 2011;JO et al, 2008). According to Figure 2, when the lactic acid concentration decreases there is an increase in the concentration of other acids.…”

Attempting to associate waste treatment to the production of clean and renewable energy, this research sought to evaluate the biological production of hydrogen using wastewater from the cassava starch treatment industry, generated during the processes of extraction and purification of starch. This experiment was carried out in a continuous anaerobic reactor with a working volume of 3L, with bamboo stems as the support medium. The system was operated at a temperature of 36°C, an initial pH of 6.0 and under variations of organic load. The highest rate of hydrogen production, of 1.1 L.d-1.L-1, was obtained with application of an organic loading rate of 35 g.L-1.d-1, in terms of total sugar content and hydraulic retention time of 3h, with a prevalence of butyric and acetic acids as final products of the fermentation process. Low C/N ratios contributed to the excessive growth of the biomass, causing a reduction of up to 35% in hydrogen production, low percentages of H2 and high concentrations of CO2in the biogas.

“…Interestingly, methane oxidizers such as the Methylococcales were detected in relatively greater abundance in regions adjacent to the AHG-the likely source of methane ( Figure 5). In the AHG, we detected some representatives of anaerobic groups that have been extensively studied because of their importance in biotechnology, for example H 2 -producing C. tyrobutyricum, or aromatic o-demethylating homoacetogen C. methoxybenzovorans (Mechichi et al, 1999;Jo et al, 2008). Spirochetes, also enriched in the AHG, have been reported as an important component of the termite gut biota because of their N 2 -fixation and cellulose degradation abilities (Lilburn et al, 2001), although we saw no evidence in this case of nifH gene expression in this group.…”

Compartmentalized microbial composition, oxygen gradients and nitrogen fixation in the gut ofOdontotaenius disjunctus

Coarse woody debris is an important biomass pool in forest ecosystems that numerous groups of insects have evolved to take advantage of. These insects are ecologically important and represent useful natural analogs for biomass to biofuel conversion. Using a range of molecular approaches combined with microelectrode measurements of oxygen, we have characterized the gut microbiome and physiology of Odontotaenius disjunctus, a wood-feeding beetle native to the eastern United States. We hypothesized that morphological and physiological differences among gut regions would correspond to distinct microbial populations and activities. In fact, significantly different communities were found in the foregut (FG), midgut (MG)/posterior hindgut (PHG) and anterior hindgut (AHG), with Actinobacteria and Rhizobiales being more abundant toward the FG and PHG. Conversely, fermentative bacteria such as Bacteroidetes and Clostridia were more abundant in the AHG, and also the sole region where methanogenic Archaea were detected. Although each gut region possessed an anaerobic core, micron-scale profiling identified radial gradients in oxygen concentration in all regions. Nitrogen fixation was confirmed by 15 N 2 incorporation, and nitrogenase gene (nifH) expression was greatest in the AHG. Phylogenetic analysis of nifH identified the most abundant transcript as related to Ni-Fe nitrogenase of a Bacteroidetes species, Paludibacter propionicigenes. Overall, we demonstrate not only a compartmentalized microbiome in this beetle digestive tract but also sharp oxygen gradients that may permit aerobic and anaerobic metabolism to occur within the same regions in close proximity. We provide evidence for the microbial fixation of N 2 that is important for this beetle to subsist on woody biomass.

“…Table 4 summarizes the key parameters and results of the most relevant studies. All the previous studies performed using immobilized Clostridium butyricum, either using PEG (Singh et al 2013), alginate bead (Zhao et al 2012), polyurethane foam (Jo et al 2008), polyurethane-activated carbon matrix (Mitchell et al 2009), or acetyl cellulose fiber (Karube et al 1982) demonstrated similar or increased molar hydrogen yield when compared to free-cell systems. There are also indications in literature that Clostridium sp.…”

“…(Ghosh and Hallenbeck 2014), but limited immobilization studies with the objective of producing hydrogen have been carried out with this strain. Some work has been done using immobilizing materials such as polyethylene glycol (Singh et al 2013), calcium alginate beads (Zhao et al 2012), polyurethane-activated carbon matrix (Mitchell et al 2009), ethylene-vinyl acetate copolymer (Lin et al 2009), polyurethane foam (Jo et al 2008), silicone gel (Lin et al 2006), and acetyl cellulose filter (Karube et al 1982). Although in these works hydrogen yield and productivity were improved using immobilized bacteria compared to suspended cells, major issues still remain about the reusability, stability, and regeneration of these immobilizing materials.…”

In order to supplement the need for alternative energy resources within the near future, enhancing the production of biohydrogen with immobilized Clostridium beijerinckii NCIMB8052 was investigated. Magnetite nanoparticles were functionalized, with chitosan and alginic acid polyelectrolytes using a layer-by-layer method, to promote bacterial attachment. Cultivating C. beijerinckii with these nanoparticles resulted in a shorter lag growth phase and increased total biohydrogen production within 100-ml, 250-ml and 3.6-L reactors compared with freely suspended organisms. The greatest hydrogen yield was obtained in the 250-ml reactor with a value of 2.1±0.7 mol H 2 /mol glucose, corresponding to substrate conversion and energy conversion efficiencies of 52±18 and 10±3 %, respectively. The hydrogen yields obtained using the immobilized bacteria are comparable to values found in literature. However, to make this process viable, further improvements are required to increase the substrate and energy conversion efficiencies.
