Production of Eicosapentaenoic acid from biodiesel derived crude glycerol using fungal culture
… culture process to produce EPA from the crude glycerol byproduct generated in biodiesel industry. This process provides both an alternative source of omega-3 fatty acids and a benefit to the biodiesel industry. Indeed, as oil prices reach historical highs, biodiesel has attracted …

Mixotrophic Production of Omega-3 Fatty Acid-rich Alga Phaeodactylum tricornutum on Biodiesel-derived Crude Glycerol
Crude glycerol is the major byproduct of the biodiesel industry. There is an abundance of this byproduct and purifying it for use in industries such as food, pharmaceutical, or cosmetic is prohibitively expensive. Developing an alternative use for crude glycerol is needed. Utilizing it as a carbon …

A Two-Dimensional Heterogeneous Numerical Model for Auto-Thermal Reforming of Synthetic Crude Glycerol in a Packed Bed Tubular Reactor
… other hydrocarbon sources have been identified. Glycerol is the by-product of biodiesel production, and with excess crude glycerol on the market, it proves advantageous to apply reforming methods to this feedstock to produce hydrogen. This work presents numerical models for a catalytic …

Use of Biodiesel-Derived Crude Glycerol for the Production of Omega-3 Polyunsaturated Fatty Acids by the Microalga Schizochytrium limacinum
Crude glycerol is the major byproduct of the biodiesel industry. In general, for every 100 pounds of biodiesel produced, approximately 10 pounds of crude glycerol are created. Because this glycerol is expensive to purify for use in food, pharmaceutical, or cosmetics industries, biodiesel producers …

BIODIESEL PRODUCTION THROUGH MICROWAVE ASSISTED TRANSESTERIFICATION OF MICROBIAL CELLS
… including biodiesel production byproduct crude glycerol and sweet sorghum juice. After cultivation, yeast cells were heated under microwave radiation to extract lipid and produce biodiesel through in-situ transesterification. Firstly, the yeast growth with crude glycerol was studied. When …

Producing Omega-3 Polyunsaturated Fatty Acids from Biodiesel Waste Glycerol by Microalgae Fermentation
Crude glycerol is a major byproduct if the biodiesel industry. Biodiesel manufacturers are currently facing the challenges of appropriate disposal of this waste material. Crude glycerol is expensive to purify for use in food, cosmetic, and pharmaceutical industries and therefore, alternative …

Development of Rhodopseudomonas palustris as a chassis for biotechnological applications
… production has resulted in a huge surplus of crude glycerol, a by-product of the process to the level of 10% by weight. This is turn has caused the price of glycerol to fall dramatically, and there are now few economically viable channels for using this resource: waste glycerol is usually …

Feedstock-To-Tailpipe Analysis of Soybean-Derived Biodiesel and Glycerol Valorization in Kansas
… via oil transesterification which also produces crude glycerol as a byproduct. The crude glycerol has low economic value and is often disposed of directly and causes environmental harm. However, glycerol is rich in carbon, hydrogen, and oxygen. Therefore, it is necessary to find ways to valorize …

Utilising microalgal mixotrophy to maximise larval nutrition
… or heterotrophic growth with glucose, glycerol or acetate. These strains had a shift in the fatty acid profile in favour of shorter chain, saturated fatty acids and an increased carbohydrate content, depending upon strain, carbon source and harvesting time. Isotopically labelled glucose …

Catalytic Conversion of Glycerol to Glycerol Carbonate Utilizing CO₂ and Dimethyl Carbonate
… Biodiesel production creates a surplus of crude glycerol, a major bottleneck. Scientists are exploring new, cost-effective uses for this abundant by-product. This research focuses on the catalytic conversion of glycerol to value-added glycerol carbonate using CO2, an abundant, non-toxic …
