Possible Interaction: Acetic Acid and Glycerol

“Calculation results indicate that acetic acid and glycerol have strong interactions, with acetic acid acting as a catalyst for these interactions in two patterns. (”

“I) Acetic acid enhances the dehydration reactions of glycerol with low energy barriers. (”

“In addition, the decomposition of acetic acid can also be promoted by the catalysis of glycerol in a certain degree.”

“Meanwhile, the production of inhibitors (e.g. acetic acid , phenol) to biocatalysts was also obviously inhibited from crude glycerol pretreated biomass.”

“At an initial pH of 4.… increased by 3.0% and glycerol yields decreased …% as the acetic acid concentration was increased from 0 to 25 mM. Raising the concentration of acetic acid to 25 … buffering capacity of the medium without obvious effects on biomass production in the cassava medium.”

“Some acetic acid bacteria have been shown to produce large amounts of glyceric acid (GA) from glycerol , which is a by-product of biodiesel fuel (BDF) production.”

“The yeast expressing mhpF gene, encoding acetylating NAD+-dependent acetaldehyde dehydrogenase, produced 74.5 g ethanol l−1, corresponding to 97.4% of theoretical maximum yield while glycerol decreased by 40% when acetic acid was added before inoculation.”

“Excitation of pyrene-1-COO− produces fluorescence from pyrene-1-COOH when a proton … during the excited singlet state lifetime of pyrene-1-COO−. The presence of glycerol as an aqueous cosolvent decreases … rates from phosphoric and acetic acid in a manner that does … the Stokes relationship on viscosity.”

“The concentrations of acetic acid produced, depending on the quantity of yeast cells added, increased in conjunction with increases in glycerol produced.”

“This indicates that glycerol may act by displacing and releasing bound acetic acid from the chitosan molecules, resulting in chitosan--glycerol hydrogen bond formation as the film dries.”

“ Acetic acid final concentration was two times lower on glycerol (2 g/l) than on glucose (4 g/l) for both micro-organisms.”

“A mutant producing large amounts of acetic acid should give high yields of glycerol, since formation of acetic acid is coupled with glycerol productioni.”
