Metagenomic analysis reveals specific BTEX degrading microorganisms of a bacterial consortium.

Petroleum hydrocarbon contamination is of environmental and public health concerns due to its toxic components. Bioremediation utilizes microbial organisms to metabolism and remove these contaminants. The aim of this study was to enrich a microbial community and examine its potential to degrade petroleum hydrocarbon.

sp. nov., isolated from saline soil in Yingkou, China.

A novel Gram-stain-positive, facultatively aerobic, slightly halophilic, endospore-forming bacterium, designated G6-18, was isolated from saline soil collected in Yingkou, Liaoning, PR China. Cells of strain G6-18 grew at 10-37 °C (optimum, 30 °C), at pH 6.0-9.

Influences of shale gas well-pad development on land use and vegetation biomass in a shale gas mining area.

It is not clear how shale gas mining would affect land use change and vegetation biomass in the villages and farmlands where was substantially influenced by human activities around the well-pads of the shale gas mining areas in Sichuan Province. Using remote sensing and image interpretation in 2012 and 2017 and in situ vegetation investigation data in 2017, we analyzed the changes of land use and biomass in well-drilling fields and buffer zones and further examined the extent affected by well-drilling and subsequently vegetation biomass loss. The results showed that shale gas mining had converted 93.

[Vibrational assignment analysis of Raman spectra of fatty alcohols].

In the present research, Raman spectra of 31 fatty alcohols were calculated by B3LYP/6-31G (d) and verified by taking methanol for example. The study results indicate that B3LYP/6-31G (d) is an effective approach for the fatty alcohols Raman spectra calculated. The vibrational assignment and Raman spectra features of 6 unbranched alcohols were discussed and the vibrating peaks derived from stretching vibration by C-O were chosen as the research target selection, and the multiple principal component regression models were established and validated with the parameters including polarizability, thermodynamic and energy parameters of the above unbranched alcohols.
