Characterization of Crude Glycerol from Biodiesel Plants
Journal of Agricultural and Food Chemistry, 2012Characterization of crude glycerol is very important to its value-added conversion. In this study, the physical and chemical properties of five biodiesel-derived crude glycerol samples were determined. Three methods, including iodometric-periodic acid method, high performance liquid chromatography (HPLC), and gas chromatography (GC), were shown to be ...

Bioconversion of crude glycerol by fungi
Applied Microbiology and Biotechnology, 2012The production of synthetic glycerol from petrochemical feedstocks has been decreasing in recent years. This is largely due to increasing supplies of crude glycerol derived as a co-product from the oleochemical industry, especially biodiesel production.

Bioconversion of crude glycerol to glycolipids in Ustilago maydis
Bioresource Technology, 2011Ustilago maydis is known to produce glycolipid-type biosurfactants. Here, we show that U. maydis is able to efficiently convert biodiesel-derived crude glycerol to glycolipids. We have optimized the medium composition and environmental factors for bioconversion of crude glycerol to glycolipids.

Applied Catalysis B: Environmental, 2013 Carbon supported Pt, Pd, and Au nanoparticles (NPs) catalysts with small diameters (2.4-3.5nm) were prepared through a solution-phase reduction method, and applied as the model catalysts for electro-oxidation of both high-purity glycerol and biodiesel ...

Microbial Conversion of Crude Glycerol to Dihydroxyacetone
Waste and Biomass Valorization, 2014Glycerol is increasingly being used as a versatile raw material within the biorefinery. However, it is very expensive to refine the crude glycerol to a high purity. In this study, the biotransformation of crude glycerol (79 % purity) using Gluconobacter oxydans spp. oxydans for the production of fine chemical dihydroxyacetone (DHA) was investigated.

Preparation of Polyurethane from Lignin and Crude Glycerol
2015Polyurethane foam (PUF) was prepared by a novel approach, using a renewable polyol derived from only biofuel production by-products, lignin and crude glycerol. This could potentially be a high value bio-refinery application for the two byproducts from cellulosic ethanol and biodiesel production, respectively.Renewable polyols were synthesized by the ...

Fungal biotransformation of crude glycerol into malic acid
Zeitschrift für Naturforschung C, 2015Abstract Malic acid production from the biodiesel coproduct crude glycerol by Aspergillus niger ATCC 9142, ATCC 10577 and ATCC 12846 was observed to occur with the highest malic acid level acid being produced by A. niger ATCC 12846.

Dihydroxyacetone production via heterogeneous biotransformations of crude glycerol
Journal of Biotechnology, 2021In this work, several immobilization strategies for Gluconobacter oxydans NBRC 14819 (Gox) were tested in the bioconversion of crude glycerol to dihydroxyacetone (DHA). Agar, agarose and polyacrylamide were evaluated as immobilization matrixes. Glutaraldehyde crosslinked versions of the agar and agarose preparations were also tested.

Investigating Crude Glycerol Electrooxidation
ECS Meeting AbstractsDecarbonization of chemical manufacturing requires a range of strategies, including the utilization of process waste. This waste can then be used in processes powered by renewable electricity, such as electrocatalysis, to synthesize other useful chemicals. In doing so, process waste is reduced and industrially-relevant chemicals are produced without
