Background n-Butyraldehyde is a high-production volume chemical produced exclusively from hydroformylation of propylene. It is a versatile chemical used in the synthesis of diverse C4-C8 alcohols, carboxylic acids, esters, and amines. Its high demand and broad applications make it an ideal chemical to be produced from biomass. Results An Escherichia coli strain was engineered to produce n-but...
Myelin is a membrane characterized by high lipid content to facilitate impulse propagation. Changes in myelin fatty acid (FA) composition have been associated with peripheral neuropathy, but the specific role of peripheral nerve FA synthesis in myelin formation and function is poorly understood. We have found that mice lacking sterol regulatory element-binding factor-1c (Srebf1c) have blunted p...
abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...
The alternative fuel butanol can be produced via acetone-butanol-ethanol (ABE) fermentation from renewable resources, i.e. biomass. Expensive feedstocks and the high costs for the separation of ABE from the dilute fermentation broth in the downstream processing have so far prohibited the industrial-scale production of bio-butanol. The low productivities and butanol yields of ABE batch fermentat...
A new class of surfactants with glycerate headgroups, that form viscous lyotropic liquid crystalline phases in excess water, have been investigated for their potential to provide sustained release matrices for depot drug delivery. Oleyl glycerate and phytanyl glycerate were used as representative surfactants of this new class, and their behaviour compared with that of glyceryl monooleate (GMO)....
Perovskite nanostructures, both hybrid organo-metal and fully inorganic perovskites, have gained a lot of interest in the past few years for their intriguing optical properties in the visible region. We report on inorganic cesium lead bromide (CsPbBr3) nanowires (NWs) having quantum confined dimensions corresponding to 5 unit cells. The addition of various hydrohalic acids (HX, X = Cl, Br, I) w...
recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. end-product reutilization, low product concentration and large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2,3-butanediol production. extraction can successfully be used...
BACKGROUND Dual extraction, high-temperature extraction, mixture extraction, and oleyl alcohol extraction have been proposed in the literature for acetone, butanol, and ethanol (ABE) production. However, energy and economic evaluation under similar assumptions of extraction-based separation systems are necessary. Hence, the new process proposed in this work, direct steam distillation (DSD), for...
In a motor with a liquid hydrocarbon fuel, the hydrocarbon fuel diffuses into the amine fuel and the fuel concentration changes with time. Therefore, the variation of amine fuel at each time should be predicted to ensure the safe start of the motor and the fuel storage should be recharged if the amine fuel concentration is out of specific range. In this work, the amount of hydrocarbon fuel diff...
