“…Dark fermentation of organic wastes for commercialization at large scale requires new routes for decreasing the cost of H 2 production (Pachapur et al, 2015b). The recent trends of replacing the media components with organic wastes to enhance H 2 production at lowered production cost are presented in Table 1.…”

The properties of eggshells (EGS) as neutralizing and immobilizing agent were investigated for hydrogen (H) production using crude glycerol (CG) by co-culture system. Eggshells of different sizes and concentrations were used during batch and repeated-batch fermentation. For batch and repeated-batch fermentation, the maximum H production (36.53±0.53 and 41.16±0.95mmol/L, respectively) was obtained with the EGS size of 33μm

“…Apple pomace and CG mixture provide nutrition suitable for microbial processes. Mixed cultures of E. aerogenes and C. butyricum could convert a mixture of pomace and CG (15 % w/v) to H 2 -1.7 mmol/mol of CG [57]. Subsequent optimization by avoiding pre-treatment and use of reducing agents, this co-culture was found to yield 19.46 mmol H 2 /L which was higher than that recorded with monocultures [58].…”

Biorefinery for Glycerol Rich Biodiesel Industry Waste

The biodiesel industry has the potential to meet the fuel requirements in the future. A few inherent lacunae of this bioprocess are the effluent, which is 10 % of the actual product, and the fact that it is 85 % glycerol along with a few impurities. Biological treatments of wastes have been known as a dependable and economical direction of overseeing them and bring some value added products as well. A novel eco-biotechnological strategy employs metabolically diverse bacteria, which ensures higher reproducibility and economics. In this article, we have opined, which organisms and what bioproducts should be the focus, while exploiting glycerol as feed.

“…The authors recommend further research on the performance of digesters in colder climates, and kinetic models of different substrates for a wider range of fermentation temperatures. In further study, the co-fermentation of different waste fractions should also be investigated to take advantage of synergies as shown by the study of Pachapur, et al [43].…”

Primary coffee processing generates important by-products-the pulp, husk and mucilage-while producing the green coffee beans. These by-products represent a large quantity of biomass and might create an adverse impact on environment if they are left to uncontrolled natural decay. In this study, the bio-methane formation potential of coffee husk, pulp and mucilage was examined in batch assays performed at 21 • C, 30 • C and 37 • C. The mean specific methane yield (SMY) from husk, pulp, and mucilage were 159.4, 244.7 and 294.5 L kg −1 volatile solids(VS), respectively, for a fermentation temperature of 37 • C; 156.8, 234.8 and 287.1 L kg −1 VS, respectively, for 30 • C; and 139.9, 196.2 and 255.9 L kg −1 VS, respectively, for 21 • C. Two kinetic models, namely, the modified Logistic model (LOG) and the modified Gompertz model (GOM), were applied to fit experimental data and the respective kinetic constants were generated. Both models exhibited a very good fit to the measured data points (R 2 > 0.987). The relationship of kinetic constants of substrates with fermentation temperatures was established and inserted into the LOG and GOM models; thus, generalized LOG and GOM models were obtained to predict SMY of the substrates at any temperature between 21 • C and 37 • C.
