Oil spillages lead to the formation of hydrocarbon and metal mixtures possessing effects on alkane-degrading bacteria that are responsible for bioremediation oil-contaminated soils waters. Studies bacterial responses mixture petroleum can inform appropriate strategies bioremediation. We employed a luminescent bioreporter Acinetobacter baylyi ADPWH_recA with alkane degradation capability evaluat...

The use of an alkane mixture that remains liquid at 77 K to freeze specimens has advantages over the use of a pure alkane that is solid at 77 K. It was found that a mixture of methane and ethane did not give a cooling rate adequate to produce vitreous ice, but a mixture of propane and ethane did result in vitreous ice. Furthermore, the latter mixture produced less damage to specimens mounted on...

The new hexanuclear mixed-valence vanadium complex [V(3)O(3)(OEt)(ashz)(2)(μ-OEt)](2) (1) with an N,O-donor ligand is reported. It acts as a highly efficient catalyst toward alkane oxidations by aqueous H(2)O(2). Remarkably, high turnover numbers up to 25000 with product yields of up to 27% (based on alkane) stand for one of the most active systems for such reactions.

Four techniques were compared for their ability to estimate forage dry matter intake (DMI) of grazing animals. In the Cage technique, 10 grazing cages were placed within each pasture, and forage inside and ou...

Differences in molecular size and shape have long been known to cause difficulties the modeling and simulation of fluid mixture behavior and generally manifest themselves as poor predictions of densities and phase equilibrium, often resulting in the need to regress model parameters to experimental data. A predictive approach to molecular geometry within the Gibbs–Helmholtz Constrained (GHC) fra...

[Introduction] CH bonds are the most ubiquitous functional group in organic compounds. CH in a neutral molecule is generally regarded as aprotic because of its low acidity. Recently, we have demonstrated the CH bonds in the cationic ethers [1, 2] and amines [3] are highly acidic. In these cations, the acidities of CH bonds are enhanced through the hyperconjugation of the CH bond with the nonbon...

AlkB and CYP153 are important alkane hydroxylases responsible for aerobic alkane degradation in bioremediation of oil-polluted environments and microbial enhanced oil recovery. Since their distribution in nature is not clear, we made the investigation among thus-far sequenced 3,979 microbial genomes and 137 metagenomes from terrestrial, freshwater, and marine environments. Hundreds of diverse a...

Microporous metal–organic frameworks (MOFs), which are new types of zeolite analogues, have been paid extensive attention because of their potential applications in gas storage, separation, and catalysis. The modular construction of MOFs allows their pore size and shape to be systematically tuned by the judicious choice of metal-containing secondary building units (SBUs) and/or bridging linkers...

By analyzing genetic similarity of rhodococci actinobacteria seven phylogenetic groups are allocated on the base alkane- 1-monooxygenases sequences. R. qingshengii F2-2 genome have been shown to alkane-1-monooxygenase genes affiliated five different types. We assume use diversity as a molecular marker identify Rhodococcus species.
