Electrodialysis is an electrochemical membrane separation technique for ionic solutions that has been used in industry for several decades. It can be used in the separation and concentration of salts, acids, and bases from aqueous solutions, the separation of monovalent ions from multivalent ions, and the separation of ionic compounds from uncharged molecules. It can be used for either electrol...

Malolactic fermentation is essential for the deacidification of high acid grape must. We have constructed a genetically stable industrial strain of Saccharomyces cerevisiae by integrating a linear cassette containing the Schizosaccharomyces pombe malate permease gene (mae1) and the Oenococcus oeni malolactic gene (mleA) under control of the S. cerevisiae PGK1 promoter and terminator sequences i...

There are two main fermentations associated with the vinification process. Alcoholic fermentation (AF), which is conducted by yeasts and malolactic (MLF), takes place as a result of metabolic activity lactic acid bacteria (LAB) genera Oenococcus, former-Lactobacillus, Pediococcus Leuconostoc. MLF defined biotransformation L-malic to L-lactic carbon dioxide in addition deacidification, contribut...

Recovery and reuse of high-acidity vegetable oil waste (higher content free fatty acids) is a major concern for reducing their effect on the environment. Moreover, conventional deacidification processes are known to show drawbacks, such as losses or higher costs wastewater treatment, which it requires great attention, especially at industrial scale. This work presents design highly efficient su...

A deacidification agent was prepared through incipient-wetness impregnation method, by using activated γ-Al2O3 as the carrier material to loaded Na2CO3, which can simultaneously remove HCl, H2S and carbonyl sulfur (COS) from blast furnace gas. The pretreatment at temperature of 550°C improve dechlorination performance. maximum breakthrough time, penetration chlorine capacity, highest utilizatio...
