Chemistry and Biphasic Reactions. Agenda 1. MeTHF Production and Quality 2. Solvent Properties ... % Degradation of THF and MeTHF THF MeTHF With typical process ... In this study, the function of the THF MO in the degradation of dioxane and THF was examined. Transcriptomic microarray data from CB1190 grown on dioxane and THF and their respective intermediates were analyzed to identify differentially expressed genes involved in the metabolism of these cyclic ethers. Photocatalytic degradation of tetrahydrofuran, 1,4-dioxane, and their mixture in a slurry photoreactor was studied. Using both GC/MS and ion chromatography (IC) methods, possible intermediates ... greater than the degradation rate of other THF-degrading strains (23). Therefore, it is important to characterize the mechanisms underlying the high-efficiency THF degradation of strain YYL. The variations of the metabolome induced by THF in strain YYL should be relevant to its THF degradation efficiency, and explor ... THF degradation and bacterial growth in incubation systems. In a previous study, the pH value was observed to decrease significantly with THF degradation by strain YYL, but the THF degradation rate was increased by coculture with strain MLY1 (). Effect of Microwave Heating on Persulfate Activation for Rapid Degradation and Mineralization of p-Nitrophenol; Extremely Slow Dynamics of an Abiotic Helical Assembly: Unusual Relevance to the Secondary Structure of Proteins By enrichment and isolation techniques bacterial strains with the capacity to grow on aliphatic cyclic ethers (dioxane, tetrahydrofuran, 1,3-dioxolane) have been isolated. Six strains that degrade tetrahydrofuran were classified as belonging to the genus Rhodococcus. One of two strains that degrade dioxane instead of or in combination with tetrahydrofuran was further characterized and a ... THF degradation and bacterial growth in incubation systems. In a previous study, the pH value was observed to decrease significantly with THF degradation by strain YYL, but the THF degradation rate was increased by coculture with strain MLY1 (). Each of the strains tested co-metabolically degraded 1,4-dioxane after growth on either propane or THF. 1,4-dioxane degradation resulted in the production of 2HEAA that was not further oxidized by the strains tested, although it was degraded by other organisms and in environmental samples. A tetrahydrofuran (THF)-degrading strain Pseudomonas oleovorans DT4 was isolated from the activated sludge of a pharmaceutical plant. P. oleovorans DT4 was able to utilize THF as the sole carbon and energy source under aerobic condition. 5 mmol/L of THF could be completely degraded by 3.2 mg/L inoculums of P. oleovorans DT4 in 14 h at pH 7.2 and 30 degrees C, with the cells concentration increasing to 188.6 mg/L. The biodegradation kinetics of tetrahydrofuran, benzene (B), toluene (T), and ethylbenzene (E) were systematically investigated individually and as mixtures by a series of aerobic batch degradation experiments initiated by Pseudomonas oleovorans DT4. ...

Another major reaction to supply C1 units to THF is the degradation of glycine by the glycine cleavage system. This is a multi-enzyme complex with three separate catalytic subunits and one substrate carrier protein. Although tetrahydrofuran-degrading Rhodococcus sp. strain YYL possesses tetrahydrofuran (THF) degradation genes similar to those of other tetrahydrofuran-degrading bacteria, a much higher degradation efficiency has been observed in strain YYL. In this study, nuclear magnetic resonance (NMR)-based metabolomics analyses were performed to explore the metabolic profiling response of strain YYL to exposure to THF.
