“…In dark fermentation, culture medium has achieved improvements in the hydrogen production. Rossi et al (2011) found that biomass pretreatment before glycerol conversion improved the hydrogen yield by fivefold. This process reduced the methanogenic bacteria in the sludge which was added as the inoculum (Rossi et al 2011).…”

“…Rossi et al (2011) found that biomass pretreatment before glycerol conversion improved the hydrogen yield by fivefold. This process reduced the methanogenic bacteria in the sludge which was added as the inoculum (Rossi et al 2011). Ngo et al (2011) improved the hydrogen yield (1.55-2 fold) compared with the un-supplemented culture by using a buffer solution (N-2-hydroxyethylpiperazine-N′-2-ethanesulfonic acid) and N 2 sparging conditions (Ngo et al 2011).…”

“…This fermentation has been improved by modifying the microorganisms, the culture media, or the reactor conditions. The bacteria applied normally came from methanogenic fermentation including several types of hydrogenic bacteria (Rossi et al 2011); however, the strains have been improved using molecular techniques (transgenic strains) (Gonzalez et al 2008) or selection techniques (eco-biotechnological) (Varrone et al 2013b), and these methodologies have allowed the increment of H 2 generation and glycerol consumption. In dark fermentation, culture medium has achieved improvements in the hydrogen production.…”

“…The traditional technology is fully developed and technologically accessible. For example, in 2010, 19 billion L of biodiesel were produced worldwide (Global Renewable Fuels Alliance 2012) and its production has been increasing constantly over the last few years (Rossi et al 2011).…”

Biodiesel, one of the most important sources of renewable energy, is produced in large quantities around the world; however, its production generates different kinds of residues and by-products which raise economic and environmental concerns. This review presents a compilation of the data on current state of transformation of residues and by-products of biodiesel industry into products that are suitable for bio-refining. The review has analyzed glycerol, biodiesel washing wastewaters, and solid residues. The technologies were described and the most significant experimental results and variables were summarized to allow researchers an easy access to this information.

We investigated the production of 2,3-butanediol by two enterobacteria isolated from an environmental consortium, Klebsiella pneumoniae BLh-1 and Pantoea agglomerans BL1, in a bioprocess using acid and enzymatic hydrolysates of soybean hull as substrates. Cultivations were carried out in orbital shaker under microaerophilic conditions, at 30 C and 37 C, for both bacteria. Both hydrolysates presented high osmotic pressures, around 2,000 mOsm/kg, with varying concentrations of glucose, xylose, and arabinose. Both bacteria were able to grow in the hydrolysates, at both temperatures, and they efficiently converted sugars into 2,3-butanediol, showing yields varying from 0.25 to 0.51 g/g of sugars and maximum 2,3-butanediol concentrations varying from 6.4 to 21.9 g/L. Other metabolic products were also obtained in lower amounts, notably ethanol, which peaked at 3.6 g/L in cultures using the enzymatic hydrolysate at 30 C. These results suggest the potential use of these recently isolated bacteria to convert lignocellulosic biomass hydrolysates into value-added products.
