Staphylococcus aureus produces bacillithiol (BSH) as major low molecular weight (LMW) thiol which functions in thiol-protection and redox-regulation by protein S-bacillithiolation under hypochlorite stress. The aldehyde dehydrogenase AldA was identified as S-bacillithiolated at its active site C...

A mathematical model was set up for anodic, cathodic and overall current efficiencies of an electrochemical cell for hypochlorite production acting as an ideal stirred reactor. A 0.06–0.20 mol dm−3 NaClO hypochlorite solution was obtained in the cell by the electrolysis of 0.25–0.50 mol dm−3 s...

Sodium hypochlorite (NaClO) solution is the most widely used disinfectant in the food industry. If NaClO solution can be used as a lubricant, the maintenance cost is reduced and the food safety is warrantied. Hypothetically, the concentration of the available chlorine in the solution affects the...

A high-throughput smartphone-based colorimetric reader (HSCR) was developed to quantitatively detect hypochlorite in aqueous solution and determine hypochlorite scavenging capacity in high-throughput format by a blue probe DMMA-IR780, which changes from deep blue to pink upon epoxidation by hypo...

High-surface area carbons are produced from biomass-based products (wood sawdust and tannic acid) by means of an environmentally friendly process based on the use of sodium thiosulfate as activating agent and an inert salt (KCl) that serves as a confinement medium for the activation reaction. Th...

Study objectiveCyanide is a deadly poison, particularly with oral exposure, in which larger doses can occur before any symptoms develop. Multiple governmental agencies highlight oral cyanide as an agent that can be used in a terrorist attack because it can be easily weaponized and is readily ava...

HypothesisTo determine the pharmacokinetics of sodium thiosulfate in the inner ear perilymph following middle ear application in Guinea pigs.

Potassium iodate is often used as a reference material to standardize a sodium thiosulfate solution which is a familiar titrant for redox titrations. In the standardization, iodine (triiodide) liberated by potassium iodate in an acidic potassium iodide solution is titrated with a sodium thiosulf...

Precious metals recovery from secondary sources is a novel alternative since they hold higher contents of several metals than average ores. In this research gold and silver were recovered from Waste Printed Circuit Boards (WPCBs) with the use of ammonia-thiosulfate solutions and the MTA 5011 ion...

Potassium thiosulfate (KTS, K2S2O3) has been shown to function as a nitrification inhibitor, thus has the potential to reduce nitrous oxide (N2O) emissions and play an important role in effective N management. The objective of this research was to determine the potential effects of KTS on N2O em...

Sodium thiosulfate is often standardized with potassium dichromate. In the standardization, iodine (triiodide) liberated by potassium dichromate in an acidic potassium iodide solution is titrated with a sodium thiosulfate solution. The iodine liberation process significantly affects the titratio...

Chemical cleavage of the sulfur-sulfur bond in halovinyl and fluoroalkyl 2-nitrophenyl disulfides is expected to yield halovinyl and fluoroalkyl thiols identical to those formed by cysteine conjugate β-lyase catalyzed cleavage of the corresponding cysteine S-conjugates. To study the potential u...

To determine if brain-acetylcholinesterase (AChE) inhibition in a marine teleost Lagodon rhomboides (pinfish) by an organophosphate pesticide (naled) is specific enough to diagnose anticholinesterase poisoning, brain-AChE inhibition by sublethal exposure in seawater was compared to brain-AChE in...

The following organophosphates were tested for their ability to induce DNA damage in a rec-type repair test with Proteus mirabilis strains PG713 (rec− hcr−) and PG273 (wild-type) and point mutations in the his− strain TA100 of Salmonella typhimurium:O,O-dimethyl-O-(1,2-dibromo-2,2-dichloroethyl)...

Electronic spectra of 1,2-dichloroethane and the 1,2-dichloroethyl radical have been calculated with ab initio CI methods in order to propose a theoretical interpretation for the well known effect of laser radiation on the pyrolysis of 1,2-dichloroethane. According to this work, the 1,2-dichloro...

Electrochemical reduction of 9,10-phenanthrenequinone, benzil and acenaphthenequinone in 1,1,1-trichloroethane (TCE)/TBAP under constant potential conditions provides an interesting entry to new coupling products through an electron-transfer reaction in solution to the chlorinated solvent. This ...

An intensely blue-coloured protecting group for carboxylic acids has been developed. The protecting group is introduced through a Steglich esterification that couples 6-(2-hydroxyethyl)azulene (AzulE) and the carboxylic acid substrate. Deprotection is effected under basic conditions by the addit...

The average daily uptake of the common food preservative sorbic acid is estimated to range from 0.01 to 1.1 mg kg−1. Sorbic acid mainly is metabolised to carbon dioxide. Minor amounts are converted to trans,trans-muconic acid (ttMA) as well as excreted unchanged into the urine. Since urinary ttM...

The objective of this work was to evaluate the effects of biological and chemical silage additives on the production of volatile organic compounds (VOC; methanol, ethanol, 1-propanol, methyl acetate, and ethyl acetate) within corn silage. Recent work has shown that silage VOC can contribute to p...

A series of sorbic and benzoic acid amide derivatives were synthesized by conjugating sorbic acid (SAAD, a1–a7) or benzoic acid (BAAD b1–b6) with amino acid esters and their antimicrobial activities were investigated against Escherichia coli, Bacillus subtilis and Staphylococcus aureus, mixed ...
