Coal-mining subsidence changed distribution of the microbiomes and their functional genes in a farmland.

Land subsidence is a serious geological event, and can trigger severe environmental and ecological issues. In this study, the influences of coal-mining subsidence on distribution of farmland microbiomes and their functional genes were investigated by 16 S ribosomal RNA (rRNA) gene and metagenome sequencing. The results showed the existence of a core microbiome, which determined the community compositions across the subsidence farmland.

Impact of Biochars on the Iron Plaque Formation and the Antimony Accumulation in Rice Seedings.

Biochar was a kind of restoration material for soil pollution. Investigation about biochar amendment on the Sb transformation in rice plants is scarce. The pot experiment was conducted to evaluate the impact of biochar on the iron plaque formation in Sb-contaminated soil, and the translocation and accumulation of Sb in rice seedings.

[Chemical Forms and Spatial Distribution of Phosphorus in the Sediment of Sihe River].

Based on the study of the content, forms, and spatial distribution of phosphorus (P) in the surface and columnar sediments of the Sihe River, the relationships between the total phosphorus (TP) and various forms of P and the basic physical and chemical properties of sediment and their ecological significance were deeply discussed. The forms of P in the sediment were defined including soluble and loosely bound P (S/L-P), Al-bound P (Al-P), Fe-bound P (Fe-P), reductant soluble P (RS-P), Ca-bound P (Ca-P), and residual P (RES-P) using the method of selectively sequential extraction. The results indicated that (TP) was 421.

Bacterial and Archaeal Community Distribution in Oilfield Water Re-injection Facilities and the Influences from Microorganisms in Injected Water.

Water flooding is widely employed for oil production worldwide. However, there has never been a systematic investigation of the microbial communities occurring in oilfield water re-injection facilities. Here, we investigated the distribution of bacterial and archaeal communities in water re-injection facilities of an oilfield, and illustrated the combined influences of environmental variation and the microorganisms in injected water on the microbial communities.

Bacterial community shift in response to a deep municipal tail wastewater treatment system.

In previous studies, ozone oyster shell fixed-bed bioreactor and membrane bioreactor (OFBR-MBR) were developed for municipal tail wastewater treatment, and qualified good effects. This study mainly discussed the bacterial community shift in response to the treatment process of OFBR-MBR. Proteobacteria, Chloroflexi, Planctomycetes, Actinobacteria and Firmicutes were dominant bacteria after ozone treatment in phylum level in OFBR-MBR; Aciditerrimonas, Blastopirellula, Pasteuria, Planctomyces, Paracoccus, Caldilinea and Defluviicoccus were adapted and enriched after ozone treatment in genus level in OFBR-MBR.

Bacterial community shift and antibiotics resistant genes analysis in response to biodegradation of oxytetracycline in dual graphene modified bioelectrode microbial fuel cell.

This study explored the biodegradation mechanisms of oxytetracycline (OTC/O) and electrochemical characteristics from the perspective of bacterial community shift and OTC resistance genes in dual graphene modified bioelectrode microbial fuel cell (O-D-GM-BE MFC). In phylum level, Proteobacteria was accounted to 95.04% in O-GM-BA, Proteobacteria and Bacteroidetes were accounted to 59.
