“…A large number of value-added chemicals such as propanediols [39], acrolein [40], dihydroxyacetone [41], glyceric acid [42], hydrogen [43], synthesis gas [44], esters [45,46], etc., can be produced from glycerol using oxidation, reduction and other catalytic reactions (Scheme 1). Oxidation of primary, secondary, and all three groups yields different molecules of C 3 acids, aldehydes, and ketones [47,48].…”

Biodiesel is one of the most attractive sources of clean energy. It is produced by the transformation of vegetable oils with up to 10% formation of glycerol as a by-product. Therefore, development of new approaches for processing bio-glycerol into such value-added chemical compounds as solketals is necessary. Thus, various six- and five-membered cyclic compounds can be prepared by acetalization of glycerol with aldehyde or ketone. The resulting glycerol oxygenates are excellent fuel additives that increase viscosity, octane or cetane number, and stability to oxidation. In addition, these products significantly reduce carbon monoxide emissions from standard diesel fuel. In this review, we highlight recent advances in the glycerol valorization for the sustainable production of bio-additives. The review includes a discussion of the innovative and potential catalysts to produce solketals.

“…The immobilized GDH shows better properties than the free GDH. Immobilization of GDH was studied in recent years [ 2 , 170 ]. The next step is to find more convenient immobilization methods for GlyDH-PQQ, where the solution might be found by the application of more protein-friendly environments such as sol–gels or conducting polymers [ 171 ].…”

Biodiesel can replace petroleum diesel as it is produced from animal fats and vegetable oils, and it produces about 10 % (w/w) glycerol, which is a promising new industrial microbial carbon, as a major by-product. One of the most potential applications of glycerol is its biotransformation to high value chemicals such as 1,3-propanediol (1,3-PD), dihydroxyacetone (DHA), succinic acid, etc., through microbial fermentation. Glycerol dehydratase, 1,3-propanediol dehydrogenase (1,3-propanediol-oxydoreductase), and glycerol dehydrogenase, which were encoded, respectively, by dhaB, dhaT, and dhaD and with DHA kinase are encompassed by the dha regulon, are the three key enzymes in glycerol bioconversion into 1,3-PD and DHA, and these are discussed in this review article. The summary of the main research direction of these three key enzyme and methods of glycerol bioconversion into 1,3-PD and DHA indicates their potential application in future enzymatic research and industrial production, especially in biodiesel industry.

“…kinases, oxidases, hydratases or decarboxylases). It is presumably, that some amounts of PQQ (dedicated to GlyDH) could have been attached by other enzymes which were present in the CE [Richter et al 2010, Almeida et al 2012, Kumar 2015, Yakushi et al 2018. In study conducted with a CE from G. oxydans not preincubated with PQQ, the highest DHA concentration was reached after 48 h and accounted for ca.…”
