The growth (glucoseand xylose-associated processes) and non-growth-mediated (maintenance energy requirements) characteristics of a metabolically engineered strain of Zymomonas mobilis capable of fermenting both glucose and xylose to ethanol have been investigated in mixed sugar fermentations. Ideally such a microorganism will also tolerate acetic acid and other inhibitory components typically p...

Acetic acid bacteria are involved in many biotechnological processes such as vitamin C, gluconic acid, miglitol or acetic acid production, and others. For a technologist trying to control the industrial process, the ability to follow the microbiological development of the process is thus of importance. During the past few years hybridization in a combination with flow cytometry has often been u...

The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...

In this research, the effects of important parameters, including the molar ratio of acetic acid to sulfur(S) , sonication time, temperature, and hydrogen the molar ratio of peroxide to sulfur on the performance of ultrasound-assisted oxidative desulfurization were studied using the response surface method (RSM). To this end, a model fuel containing n-decane and dibenzothiophene at a concentrati...

A type of heat-curing phosphate binder was proposed, and orthogonal experiments based on the tensile strength sand samples determined that optimal composition phosphoric acid: water: aluminum hydroxide: magnesium oxide: boric acid = 300: 70: 60: 9: 8. Adding 10% polyvinyl alcohol (PVA) solution during mixture process can significantly improve 24 h samples. When adding 30 g 8 PVA solution, initi...

Microbial cell factories with the ability to maintain high productivity in the presence of weak organic acids, such as acetic acid, are required in many industrial processes. For example, fermentation media derived from lignocellulosic biomass are rich in acetic acid and other weak acids. The rate of diffusional entry of acetic acid is one parameter determining the ability of microorganisms to ...

Indole-a-acetic acid is well known as an inducer as well as an inhibitor of several growth and differentiative processes in plants, lower metazoa, and microorganisms. The principle of unity in biology suggests that these diverse effects of indole-3-acetic acid may all be consequences of interference with a common reaction or series of reactions; therefore, the study of the action of indolea-ace...

Both sexes of the noctuid moths Lacanobia subjuncta (Grote & Robinson), Mamestra configurata Walker (bertha armyworm) and Xestia c-nigrum (L.) (spotted cutworm) are attracted to the combination of acetic acid and 3-methyl-1-butanol (isoamyl alcohol). A controlled-release system for use of this attractant in traps was comprised of separate polypropylene vials for each chemical, with the chemical...

Haa1 is a transcriptional activator required for Saccharomyces cerevisiae adaptation to weak acids. Here we show that the constitutive HAA1-overexpressing strain acquired a higher level of acetic acid tolerance. Under conditions of acetic acid stress, the intracellular level of acetic acid was significantly lower in HAA1-overexpressing cells than in the wild-type cells.

Silt,?I have the honour to ask you to publish tho followingnote on the uso of acetic acid as an antidote to carbolic acid. Once when I was cleaning a wound I had to dip my hand over and over again into carbolic lotion (1 in 40), and L soon found a painful sensation in my arm from fingers to shoulder joint. I then found that I had a scratch on my finger. [ applied some acetic acid on a piece of ...
