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 ...
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 ...
Synthesis of Edible Vegetable Oils Enriched with Healthy 1,3-Diglycerides Using Crude Glycerol and Homogeneous/Heterogeneous Catalysis
(Springer, 2020-01)
Commercial edible vegetable oils in which part of their triglycerides are substituted with 1,3-diglycerides are healthier for human consumption than the original oils. This is because the human metabolism of 1,3-diglycerides ...
Synthesis and catalytic evaluation of acidic carbons in the etherification of glycerol obtained from biodiesel production
(Elsevier Science, 2021-07)
In this paper, the catalytic behaviour of carbonaceous system (Ccs) functionalized with –SO3H groups were studied in the etherification of refined (Gly) and crude glycerol (GlyC), with benzyl alcohol (BA). This Ccs was ...
High yield to 1-propanol from crude glycerol using two reaction steps with Ni catalysts
(Multidisciplinary Digital Publishing Institute, 2020-06-02)
The objective of the present work is to achieve high yield to 1-propanol (1-POH) by crude glycerol hydrogenolysis in liquid phase and find an alternative to the use of noble metals by employing Ni catalysts. Two Ni catalysts ...
Hydrogen-rich gas production by steam and oxidative steam reforming of crude glycerol over Ni-La-Me mixed oxide catalysts (Me= Ce and/or Zr)
(Elsevier Science, 2018-06)
The production of H 2 -rich gaseous mixtures from steam and oxidative steam reforming of crude glycerol was investigated on catalysts with general formula Ni(12 wt.%)-La 2 (Ce 1-x Zr x ) 2 O 7 (x = 0, 0.5, 1). The catalysts ...
Production of a microbial emulsifier with biotechnological potential for environmental applications
(Elsevier Science, 2019-02)
The present work reports the production of bioemulsifiers (BEs) by an environmental bacterium closely related to Bacillus spp., using agro-industrial wastes and by-products as low-cost carbon sources. Maximum emulsifying ...
Production in stirred-tank bioreactor of recombinant bovine chymosin B by a high-level expression transformant clone of Pichia pastoris
(Academic Press Inc Elsevier Science, 2016-07)
An intense screening of Pichia pastoris clones transformed with the gene of bovine chymosin under methanol-inducible AOX1 promoter was performed, obtaining a transformant clone with a higher milk-clotting activity value ...
Optimization of bacterial bioaugmentation for groundwater Mn removal using a waste-based culture medium and lyophilization
(Royal Society of Chemistry, 2020-10)
Water Impact StatementBioaugmentation for groundwater Mn removal has been performed with fresh bacterialinoculums. Lyophilized inoculums will solve the problems of keeping bacteria viableand transporting large culture ...
