The corrosion behavior of mild steel in the presence of acetic acid (CH3COOH) and carbon dioxide (CO2) has been investigated using electrochemical techniques and weight-loss measurements. Electrochemical measurements have shown that the presence of acetic acid affects predominantly the cathodic reaction. The acetic acid effect is much more pronounced at elevated temperatures when catastrophic c...

The title compound, C(8)H(9)NO(4)S, is of inter-est as a precursor to biologically active sulfur-containing heterocyclic cmpounds. The crystal structure displays the classical O-H⋯O inter-molecular hydrogen bonding typical for carboxylic acids forming dimers. Symmetry-related dimers are, in turn, linked through head-to-tail pairs of inter-molecular N-H⋯O inter-actions, giving rise to a zigzag c...

The compound 3-(2’-methyl-4’-amino-S’-pyrimidylmethyl)-4-methylthiazole-S-acetic acid (thiamine acetic acid) has been identified as an intermediate in the metabolism of thiamine by a soil microorganism. Evidence is presented which indicates the compound 2-oxy-3-(2’-methyl-4’-amino5’-pyrimidylmethyl)-4-methylthiazole-S-acetic acid (2-oxythiamine acetic acid) is also an intermediate in the metabo...

Recovery of metals from chromated copper arsenate (CCA)-treated southern pine wood particles was investigated using binary acid solutions consisting of acetic, oxalic, and phosphoric acids in a microwave reactor. Formation of an insoluble copper oxalate complex in the binary solution containing oxalic acid was the major factor for low copper removal. Furthermore, the possible complexation of ac...

Sour and salt taste interactions are not well understood in the peripheral gustatory system. Therefore, we investigated the interaction of acetic acid and NaCl on taste processing by rat chorda tympani neurons. We recorded multi-unit responses from the severed chorda tympani nerve (CT) and single-cell responses from intact narrowly tuned and broadly tuned salt-sensitive neurons in the geniculat...

Acetobacter pasteurianus strains IFO3283, SKU1108, and MSU10 were grown under acetic acid fermentation conditions, and their growth behavior was examined together with their capacity for acetic acid resistance and pellicle formation. In the fermentation process, the cells became aggregated and covered by amorphous materials in the late-log and stationary phases, but dispersed again in the secon...

Growth of some xylose fermenting yeasts, Candida shehatae, Pichia stipitis CBS5773, fusant F101 and fusant F198, was completely inhibited in xylose medium added with 0.5% v/v acetic acid which caused the reduction of pH to 4.1. Only one xylose fermenting strain, Pachysolen tannophilus NRRL-Y2460, showed relatively low growth and ethanol fermentation. However, in the medium added with 1.0% v/v a...

The role and metabolism of indole-3-acetic acid in gram-negative bacteria is well documented, but little is known about indole-3-acetic acid biosynthesis and regulation in gram-positive bacteria. The phytopathogen Rhodococcus fascians, a gram-positive organism, incites diverse developmental alterations, such as leafy galls, on a wide range of plants. Phenotypic analysis of a leafy gall suggests...

Acetobacter spp. are used for industrial vinegar production because of their high ability to oxidize ethanol to acetic acid and high resistance to acetic acid. Two-dimensional gel electrophoretic analysis of a soluble fraction of Acetobacter aceti revealed the presence of several proteins whose production was enhanced, to various extents, in response to acetic acid in the medium. A protein with...
