http://oilfieldwiki.com/wiki/Glyoxal 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.
WebIn the study, we report that a safe and simple way for upgrading inferior rubber wood through the combined modification of environment-friendly MUG resin was synthesized from glyoxal, melamine, urea, and other additives. MUG-treated wood samples were prepared with six different MUG resin concentrations (5, 15, 25, 35, 45, and 55 wt %) into …
