The valorization of glycerol: Economic assessment of an innovative process for the bioconversion of crude glycerol into ethanol and hydrogen

Selection and identification of microorganisms present in the treatment of wastewater and activated sludge to produce biohydrogen from glycerol

“…According Santos (2012) [24] the Brazilian biodiesel production in 2035 will be around 40 million cubic meter, only with transesterification process and the worldwide production will overpass 100 million cubic meter. With the worldwide increased use of biofuels, products such as glycerol have accumulated in the environment [8,36]. For every nine tonnes of biodiesel produced, around one tonne of crude glycerol is formed [10,14].…”

Biodiesel Industry Waste: A Potential Source of Bioenergy and Biopolymers

“…These studies provide necessary inputs for exploiting CG as feed for these bacteria. It becomes all the more significant in view of the fact that CG contains a few contaminants which may prove inhibitory to bioprocesses [24,[35][36][37]. However, it has been shown that CG is as good as PG since the trace amounts of contaminants was helpful in improving bacterial growth and H 2 production [26,38].…”

Effect of hydraulic retention time on the modelling and optimization of joint 1,3 PDO and BuA production from 2G glycerol in a chemostat process

“…On the other hand, an increasing number of studies are suggesting that exploring the available diversity in nature to developing mixed microbial consortia (MMC) is a promising alternative approach, that can provide interesting results (for instance in terms of conversion efficiencies, reduced substrate and operating costs due to unnecessary substrate pretreatment or sterilization, etc. ), particularly in the case of industrial waste feedstock containing compounds of undefined composition [19][20][21][22]. In fact, the ability of the enriched MMC to create synergistic effects can help degrading complex substrates with different grades of impurities, such as i.e.…”
