Effective removal of alkali and alkaline earth metals (AAEM) is of great significance for promoting biomass pyrolysis. In this study, demineralization via hydrothermal pretreatment was performed, and the effect on the pyrolysis behavior was evaluated by thermogravimetric analysis (TGA) and thermal pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS). The effects of reaction temperature, time, and pH on the dissolution rate of K, Ca, and Mg were investigated.

In NSCLC patients with EGFR mutations, and ALK fusion oncogene, chemotherapy is ineffective; however, targeted and pulse therapies may be used as alternative treatment options. Elemene can cross the blood-brain barrier and enter the brain tissue.

Based on16S rRNA gene sequence analysis, strain YS-37 was most closely related to Lysobacter pocheonensis Gsoil 193 (97.0%), Lysobacter dokdonensis DS-58 (96.

The As(III)-oxidizing bacterium Agrobacterium tumefaciens GW4 displays positive chemotaxis towards 0.5-2 mM As(III).

In this study, we found that aioE is induced by As and located in the arsenic island near the As oxidase genes aioBA and co-transcripted with the arsenic resistant genes arsR1-arsC1-arsC2-acr3-1. AioE belongs to TrkA family corresponding the electron transport function with the generation of NADH and H.

A Gram-staining-negative, rod-shaped, motile by gliding and facultative anaerobic bacterial strain, YS-25T, was isolated from a sludge of a manganese mine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YS-25T formed a single branch within the strains of the family Sphingobacteriaceae and showed low similarities to Pedobacter arcticus CCTCC AB 2010223T (91.7 %), 'Pedobacter zeaxanthinifaciens' TDMA-5 (91.

A Gram-stain-positive, strictly aerobic, non-motile and rod-shaped bacterial strain, designated YS-17T, was isolated from soil in the Lengshuijiang antimony mine, Hunan Province, China. Comparative 16S rRNA gene sequencing analysis clustered it with Flavihumibacter strains, and strain YS-17T was most closely related to Flavihumibacter cheonanensis WS16T (97.2 % similarity), Flavihumibacter petaseus T41T (96.
