Electrodialysis of acetic acid fermentation broths
Electrodialysis (ED) was studied as a method to recover and purify acetate from model solutions and fermentation broths such as vinegar and calcium magnesium acetate (CMA). An initial evaluation of the ED stack with model sodium chloride solutions revealed that increasing the flow rate increased …

The Dissociation Constant of Acetic Acid at 25°c
The dissociation constants of weak acids can be determined from thermodynamic data obtained from cells without liquid junction. The method was developed by Harned and his students.

The Inhibitory Effects of Acetic Acid on Enteric Bacteria
The surface of a multicellular organism, exposed to the external environment, either directly or indirectly, is inhabited by a specific microbial flora. This holds true regardless of the species or environment of the multicellular organism's The microbial flora of the multicellular organism, man, …

Chemical ablation of the Gallbladder with Acetic acid(50%)
… chemical ablation of dog gallbladder using 50% acetic acid. Five beagle dogs(8-10Kg) underwent percutaneous transhepatic cholecystostomy using sonographic guidance after general anesthesia. Cystic duct occlusion was done by using of N-butyl-2-cyanoacrylate and coils percutaneously. After …

High Resolution Acetic Acid Survey and Water Vapor Radiometer
… data and achieve great scientific goals. For our acetic acid survey, a better phase correction technique can not only detect weaker transitions of large molecules, but also increase the map resolution of hot cores. Water vapor radiometers (WVRs) are designed to improve the technique by observing …

Mechanisms of monohalogenated acetic acid induced genomic DNA damage
… health and pregnancy outcomes. Monohalogenated acetic acids (monoHAAs) iodoacetic acid (IAA), bromoacetic acid (BAA), and chloroacetic acid (CAA) are genotoxic and mutagenic with the consistent rank order of toxicity of IAA > BAA > CAA. The comparative toxicity of these compounds was highly …

Bioconversion of lignocellulosic hydrolysate to acetic acid using Moorella thermoacetica
… of bioconversion of lignocellulosic sugars to acetic acid by Moorella thermoacetica strain ATCC 39073 was conducted. Four different hydrolysates obtained after steam pretreatment of lignocellulosic biomass were selected and fermented to acetic acid in batch fermentations. The bacterial strain …

Mechanistic characterization of acetic acid resistance enzymes of Acetobacer aceti
… (<em>A. aceti</em>) is a Gram-negative, acidophilic bacterium that is used for the industrial production of acetic acid from ethanol. Oxidation of ethanol by membrane-bound oxidoreductases provides energy for A. aceti and the production of high concentrations of acetic acid is an …

Evaluation of solvents for extraction of acetic acid from aqueous solutions
… is used to concentrate aqueous solutions of acetic acid produced in the esterification of cellulose and in other manufacturing processes because acetic acid and water are not easily separated by direct rectification. Liquid extraction of acetic acid must always be followed by solvent-recovery …

The recovery of acetic acid from wastes of tanning extract manufacture
… chips. The liquors are highly corrosive due to acetic acid contained therein along with lesser quantities of other organic substances common to woody materials. Recovery of the acetic acid would be desirable from two standpoints: (1) the value of the acetic acid, and (2) reuse of the acid-free …

Enhancing Bioethanol Fermentation through Removal of Acetic Acid Using Liquid-Liquid Extraction
… total greenhouse gas emission by at least 60 %. Acetic acid has been shown to be one of the most ubiquitous fermentation inhibitors in a bioethanol production facility which slows down the bioethanol production and reduces its yield through inhibition of the ethanol producing microorganisms. The …
