Regional dietary habits and cooking methods affect the prevalence of specific food allergies; therefore, we determined the effects of various pH conditions on major peanut allergens. Peanut kernels were soaked overnight in commercial vinegar (pH 2.3) or acetic acid solutions at pH 1.0, 3.0, or 5.0. Protein extracts from the sera of seven patients with peanut-specific IgE levels >15 kU(A)/L were...

BACKGROUND To compare the efficacy and treatment session numbers of acetic acid to that of ethanol sclerotherapy for the treatment of simple renal cysts. Between February 2004 and June 2013, 86 patients with simple renal cysts underwent percutaneous aspiration and injection of 50 %-acetic-acid (42 cysts) and 95 %-ethanol (44 cysts). The patient demographics, volume reduction rate, number of tre...

(• ¯ " ‡ OE[ˆê • ")(‰ª • " • º ƒ') Some substances to promote the production of antibiotics were re ported already by many authors. According to Knight1) the use of corn steep liquor in the media of Penicillium chrysogenum increased the production of Penicillin. Koffler and others2) investigated on the promoting elements of corn steep liquor and reported that one element was the combination of ...

Yeast belonging to the genera Brettanom}'ces and Dekkera are noted for spoiling cellar and bottled wine through the production of haze, turbidity and acetic acid. However, I was unable to find information on the use of these yeasts for the expressed purpose of acetic acid production. Sixty yeast strains belonging to these, and several other genera, from the ARS Culture Collection, Peoria, IL, w...

An attempt has been made to recover acetic acid from aqueous solutions using supported liquid membrane (SLM) technique. A flat sheet polytetrafluoroethylene (PTFE) supported membrane impregnated with vegetable oils was tested for transport of acetic acid. The permeation of acetic acid was studied by varying the experimental conditions namely strength of stripping phase, stirring speed and selec...

The aerobic oxidation of indole-3-acetic acid catalyzed by horseradish peroxidase produces 1268 nm emission characteristic of singlet oxygen. Lactoperoxidase also oxidizes indole-3-acetic acid to produce singlet oxygen, but in contrast to horseradish peroxidase, this enzyme system requires hydrogen peroxide. In both of these systems, the intensity of the 1268 nm emission is small due to quenchi...

Abstract—Alumina supported platinum and tin catalysts with different loadings of Pt and Sn were prepared and characterized by low temperature N2 adsorption/desorption, H2-temperature programed reduction and CO pulse chemisorption. Pt and Sn below 1% loading were suitable for acetic acid hydrogenation. The best performance over 0.75Pt1Sn/Al2O3 can reach 87.55% conversion of acetic acid and 47.39...

INTRODUCTION Saccharomyces cerevisiae is the micro-organism of choice for the conversion of fermentable sugars released by the pre-treatment of lignocellulosic material into bioethanol. Pre-treatment of lignocellulosic material releases acetic acid and previous work identified a cytochrome oxidase chaperone gene (COX20) which was significantly up-regulated in yeast cells in the presence of acet...

Mitochondrial outer membrane permeabilization is a key event in apoptosis processes leading to the release of lethal factors. We have previously shown that absence of the ADP/ATP carrier (AAC) proteins (yeast orthologues of mammalian ANT proteins) increased the resistance of yeast cells to acetic acid, preventing MOMP and the release of cytochrome c from mitochondria during acetic acid - induce...
