Crude glycerol by transesterification process from used cooking oils: Characterization and potentialities on hydrogen bioproduction
This study evaluated the potential bioconversion of crude glycerol from biodiesel production, applying used cooking oil for biohydrogen production by fermentative bacteria consortia. The pretreatment of crude glycerol was ...
Dihydroxyacetone production via heterogeneous biotransformations of crude glycerol
(Elsevier Science, 2021-11)
In 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 ...
Polyhydroxyalkanoate production from crude glycerol by newly isolated Pandoraea sp. Polyhydroxyalkanoate production from crude glycerol
A new bacterial strain was isolated from Atlantic rainforest in Brazil for polyhydroxyalkanoate (PHA) production utilizing crude glycerol from biodiesel industry (CG) and it was identified as Pandoraea sp. MA03. Shake flask ...

Use of glycerol, waste glycerol from biodiesel production and other protic solvents in bioactive α,β-unsaturated ketones synthesis
Glycerol is the main co-product from biodiesel production and has been recognized as a sustainable solvent. Herein, we used glycerol and waste glycerol in synthesis of two bioactive α,β-unsaturated ketones (E,E)-1,5-diph ...
Sodium salts solubility in ternary glycerol+water+alcohol mixtures present in purification process of crude glycerol from the biodiesel industry
(Elsevier Science, 2019-10-01)
In this work sodium salts solubility data were obtained for relevant systems involved in crude glycerol purification processes. Several binary and ternary mixtures of glycerol + water and glycerol + water + alcohol were ...
Preparation of activated charcoal from Acrocomia aculeata for purification of pretreated crude glycerol
Activated charcoal was prepared from Acrocomia aculeata (macaúba) endocarp by ZnCl2 activation and then used for the adsorptive purification of pretreated crude glycerol (CG) containing pigments, such as β-carotene. The ...
Exploration of Brazilian biodiversity and selection of a new oleaginous yeast strain cultivated in raw glycerol

Zeolitic core@shell adsorbents for the selective removal of free glycerol from crude biodiesel
(Wiley VCH Verlag, 2015-06)
Selective adsorption of free glycerol from crude biodiesel was investigated by using mesoporous silica spheres coated with a thin shell of microporous silicalite-1. A polycrystalline silicalite-1 shell was formed upon first ...
