Linoleic acid and monomethyldecenylsuccinic acid were tested as uncoupling agents for energy linked functions of corn mitochondria. 2,4-dinitrophenol was used as a standard for comparison. Both compounds uncoupled oxidative phosphorylation, released oligomycin-blocked respiration, and accelerated adenosine triphosphatase. Linoleic acid uncoupled calcium-activated phosphate accumulation and the ...

Molecular imprinted polymers (MIP) are considered one of the most promising selective and novel separation methods for removal phenolic compound in wastewater treatment. MIP are crosslinked polymeric materials that exhibit high binding capacity and selectivity towards a target molecule (template), purposely present during the synthesis process. In this work MIP were prepared in a bulk polymeriz...

In the present study, ultrasound-assisted Fe3O4@TiO2 magnetic nanocomposite was employed to catalytic oxidation of 2,4-Dinitrophenol. The catalyst features were characterised by SEM, TEM, XRD, BET, FTIR, VSM, DLS and TGA techniques. effect operational parameters i.e. pH, amount, 2,4-Dinitrophenol concentration ultrasound power on DNP removal examined optimised in terms sono-catalytic degradatio...

The bacterial strain RB1 has been isolated by enrichment cultivation with 2,4-dinitrophenol as the sole nitrogen, carbon, and energy source and characterized, on the basis of 16S rRNA gene sequence comparison, as a Rhodococcus species closely related to Rhodococcus opacus. Rhodococcus sp. strain RB1 degrades 2,4-dinitrophenol, releasing the two nitro groups from the compound as nitrite. The rel...

Oxidative phosphorylation has been studied in mitochondria and homogenates of six normal and five solid neoplastic rat tissues by determination of P :0 and control ratios and through the use of fluoride and dinitrophenol. In mitochondria prepared from the eleven tissues, P :O ratios with glutamate varied from 2.2 to 2.8, and with succinate from 1.1 to 2.0. Similar control of respiration by phos...

Background: Phenol and its derivatives like dinitrophenol and pentachlorophenol (carbolic acid) are widely used as insecticides, but they are very toxic substances. Phenol is a general protoplasmic poison with corrosive local effects that denature proteins. Poisoning with phenol compounds may occur by ingestion, inhalation, and absorption through skin. In this report we presented the toxicity...

1. Cystamine (2,2'-diaminodiethyl disulphide) caused an unmasking of mitochondrial adenosine triphosphatase and a leakage of Mg(2+) from the mitochondria, and decreased the stimulation of adenosine triphosphatase by 2,4-dinitrophenol. When Mg(2+) was added, cystamine potentiated the activation of adenosine triphosphatase by 2,4-dinitrophenol. 2. Cystamine was without effect on the adenosine tri...

At the end of a 4 hour absorption period approximately 95% of the sodium absorbed by bean plants was retained in the secondary roots. The sodium translocated to the shoot was retained in the stem.2,4-Dinitrophenol decreased the amount retained in the secondary roots of bean plants and increased the amount translocated to the shoot. The stem retained most of the translocated sodium.Bean plants w...

Abstract. To investigate the composition, variation, and sources of nitrated phenols (NPs) in winter Beijing, gas-phase NPs were measured by a chemical ionization long time-of-flight mass spectrometer (CI-LToF-MS). A box model was applied to simulate secondary formation process NPs. In addition, primary resolved non-negative matrix factorization (NMF) model. Our results showed that contributed ...

The Front Cover represents how purple bacterial cells utilized in biohybrid electrochemical systems hit, or miss, their “target electrode” with photo-induced electrons depending on the concentration of dinitrophenol at which they are exposed.
