Abstract:
To obtain a new quantitative determination method of Acetoin for reducing the cost of testing and the workload in the process of strain breeding. In an alkaline environment, using 3,5-dinitrosalicylic acid with strong oxidizing properties to azeotrope with Acetoin, 3,5-dinitrosalicylic acid is reduced to 3-amino-5-nitrosalicylic acid and 3-amino-5-nitrosalicylic acid are red-brown substances. The content of Acetoin can be obtained by detecting the absorbance at 540 nm. This new quantitative determination method of Acetoin is a simple, rapid and low-cost method for quantitative determination of

Abstract:
An assay for determination of galacturonic acid with 3,5-dinitrosalicylic acid was developed that substantially extends the linear range of detection compared to a previously published method with this reagent. In the improved assay, galacturonic acid was detected with a reagent containing 44 mM 3,5-dinitrosalicylic acid, 4 mM sodium sulfite, and 375 mM sodium hydroxide. The absorbance of the solution after reaction with galacturonic acid was determined at 575 nm and was linear at concentrations of galacturonic acid up to 50 μmol, with a lower limit of detection at ~400 nmol.

Abstract:
The photodegradation of dinitrosalicylic acid (DNS) by photoexcited uranyl ion was studied in aqueous solutions. The failure of DNS to degrade directly with light highlights the importance of the photoexcited uranyl ion in controlling the photochemical processes. Fluorescence quenching studies showed that an electron-transfer process from the DNS to the excited uranyl ion is involved leading to the formation ofUO2+/DNS•+radical pair complex as an initial step. Illumination of theUO22+/DNS solution in presence of oxygen results in mineralization of DNS. The results are explained on the basis of

Abstract:
Despite intensive efforts put on prevention of environment pollution by nitroaromatic compounds, these xenobiotics have not been eliminated from the biosphere. The physicochemical properties make nitroaromatics extremely recalcitrant to biodegradation. Therefore, microbial degraders of these pollutants are sought after. This paper reports preliminary results of the study on degradation of 3,5-dinitrosalicylic acid (DNS) by a basidiomycetous fungus Phanerochaete chrysosporium under stationary conditions in a culture medium containing 0.05–0.5% v/v of DNS.

Abstract:
The crystal structures of the proton-transfer compounds of 3,5-dinitrosalicylic acid (dnsa) with a series of common monocyclic heteroaromatic amines (pyridine, 4-cyanopyridine, pyridine-4-carboxylic acid, 2,6-diaminopyridine, and 2-aminopyrimidine) have been determined and the hydrogen-bonding associations in each analyzed. The compounds are the adduct [(C5H6N)+(dnsa)–· (dnsa)] (1), the 1 : 1 salts [(C6H5N2)+(dnsa)–] (2), [(C6H6NO2)+(dnsa)–] (3), [(C5H8N3)+(dnsa)–] (4), and the 2 : 2 ethanol hemi-solvate [2(C4H6N3)+·2(dnsa)–· 0.5(EtOH)] (5).

Abstract:
A new batch mode reactor was constructed to conduct continuous biodegradation of 3,5-dinitrosalicylic acid. Various types of matrices with immobilized Phanerochaete chrysosporium were immersed in a solution containing pollutant and mineral nutrients. Three parameters were chosen to optimize the process. The nitrate and nitrite ions concentrations and HPLC analysis were used to prove the biodegradation of 3,5-dinitrosalicylic acid, and the mixed effects model using one-factor ANOVA was used for statistical calculations. The results showed the correlation between the initial pH, a medium composi

Abstract:
Quantification of carbohydrates by the anthrone method is a colourimetric assay. In this method, first, the complex carbohydrates are hydrolysed in a highly acidic medium, resulting in monosaccharides. Thereafter, these monosaccharides are dehydrated to form 5-hydroxymethylfurfural (5-HMF) or 2-furfural (2-F), followed by reacting with anthrone reagent. This reaction produces a blue-green complex which is colourimetrically determined.
