Decomposition of humic substances (HSs) is a slow and cryptic but non-negligible component of carbon cycling in sediments. Aerobic decomposition of HSs by microorganisms in the surface environment has been well documented; however, the mechanism of anaerobic microbial decomposition of HSs is not completely understood. Moreover, no microorganisms capable of anaerobic decomposition of HSs have be...

This work explores thoroughly the reaction network of the partial oxidation of phenylmethanol at the TiO(2)-solvent interface under photocatalytic conditions by using a first-principles continuum solvation method. We demonstrate that the photocatalytic oxidation of phenylmethanol has a complex reaction network with dual pathways. The dimer pathway dominates the mechanism under aerobic condition...

Most often, our waterways are being polluted by municipal, agricultural and industrial wastes. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria in decomposing the waste, thereby robbing other aquatic organisms of the oxygen they need to live. In this paper, we consider the solution of the optimal control problem for the modified Dissolve Oxygen(DO)/ Biol...

Decomposition is essential for carbon and nutrients cycling for all ecosystems (Hoorens et al., 2003). In lentic aquatic environments (e.g., lakes and reservoirs), aquatic macrophytes are the main autochthonous detritus source, and their mineralization is fundamental for maintaining biogeochemical cycles, associated with energy flux and detritus food-webs. (Bianchini Junior et al., 2014). In di...

Rapidly proliferating cells such as cancer cells and embryonic stem cells rely on a specialized metabolic program known as aerobic glycolysis, which supports biomass production from carbohydrates. The fruit fly Drosophila melanogaster also utilizes aerobic glycolysis to support the rapid growth that occurs during larval development. Here we use singular value decomposition analysis of modENCODE...

Photocatalysts A 3D Cu-based PH3 decomposition catalyst with a scaly morphology is synthesized via hydrothermal loading, exhibiting notable efficiency in under low-temperature nd micro-aerobic conditions. The deactivation of the found to be attributable formation Cu3P. In article number 2301169, Riguang Zhang, Fei Wang, Kai Li, and co-workers suggest potential utility deactivated photocatalysis...

The Lactobacillus buchneri CD034 strain, known to improve the ensiling process of green fodder and the quality of the silage itself was transcriptionally analyzed by sequencing of transcriptomes isolated under anaerobic vs. aerobic conditions. L. buchneri CD034 was first cultivated under anaerobic conditions and then shifted to aerobic conditions by aeration with 21% oxygen. Cultivations alread...

(DAF)Pd(OAc)2 (DAF = 4,5-diazafluorenone) catalyzes aerobic intramolecular aryl C-H amination with N-benzenesulfonyl-2-aminobiphenyl in dioxane to afford the corresponding carbazole product. Mechanistic studies show that the reaction involves in situ generation of peroxide species from 1,4-dioxane and O2, and the reaction further benefits from the presence of glycolic acid, an oxidative decompo...

A detailed investigation of Valsartan`s light-induced degradation is reported. Based on UPLC-HRMS studies stressed solutions several pathways are proposed. Some the proposed structures were obtained by forced experiments. Examination analytical data including crystal allowed for structural revision one literature-known degradant. In addition, irradiation under aerobic conditions revealed furthe...

This study aimed to discuss and describe the oxygen consumption during aerobic mineralization of organic products (cells and excretion products) from five unialgal cultures: Cryptomonas sp., Microcystis aeruginosa, Anabaena spiroides, Thalassiosira sp. and Aulacoseira granulata. These species were isolated from Barra Bonita reservoir (22 degrees 29' S and 48 degrees 34' W) and cultivated in the...
