WebGlycolic acid (GA) and glyoxal (GO) are two glycolysis by-products approved as biocides for surface disinfection, whose antimicrobial action remains to be understood. This study focused on the understanding of the antimicrobial activity of GA and GO against two foodborne pathogens, Bacillus cereus and Pseudomonas fluorescens. WebAmmonium Addition (and Aerosol pH) Has a Dramatic Impact on the Volatility and Yield of Glyoxal Secondary Organic Aerosol Environmental …

Glyoxal Definition & Meaning Merriam-Webster Medical
WebThe determination of glyoxal and glyoxalic acid in aldehyde solution was performed by high performance liquid chromatography (HPLC). The proper derivatization conditions were as follows: the reaction temperature of 70 degrees C, the pH of the system of 1.75; the molar ratio of DNPH to carbonyl of 6, the reaction time of 150 min. WebThe reaction of phenylglyoxal (PGO), glyoxal (GO), and methylglyoxal (MGO) with amino acids were investigated at mild pH values at 25 degrees. These aldehydes reacted most rapidly with arginine and the rate of reaction increased with increasing pH values.
