Mining activity for rare earth elements (REEs) has caused serious environmental pollution, particularly soil ecosystems. However, the effects of REEs on microbiota are still poorly understood. In this study, soils were collected from abandoned sites a mine, and structure, diversity, co-occurrence patterns evaluated by Illumina high-throughput sequencing targeting 16S rRNA genes. Although developed significantly along with natural restoration, microbial structure site 10 years differed that...
Fixation ability of five common fixation solutions, including 2.5% glutaraldehyde, 10% formalin, 4% paraformaldehyde, methanol/acetone (1:1), and ethanol/acetic acid (3:1) were evaluated by using atomic force microscopy in the present study. Three model bacteria, i.e., Escherichia coli, Pseudomonas putida, Bacillus subtilis applied to observe above methods for morphology preservation bacterial cells surface ultrastructures. All could effectively preserve cell morphology. However, preserving...
Surface-enhanced Raman scattering (SERS) has recently been proved to be a promising technique for characterizing the chemical composition of biofilm matrix. In present study, fully understand variations during formation, SERS based on silver colloidal nanoparticles was applied evaluate components in matrix at different growth phases, including initial attached bacteria, colonies, and mature biofilm. Meanwhile, atomic force microscopy also study changes morphology. Three model Escherichia...
Plant-associated bacteria are of great interest because their potential use in phytoremediation. However, ability to survive and promote plant growth metal-polluted soils remains unclear. In this study, a soilborne Cd-resistant bacterium was isolated identified as Enterobacter sp. strain EG16. It tolerates high external Cd concentrations (Cd(2+) MIC, >250 mg liter(-1)) is able produce siderophores the hormone indole-3-acetic acid (IAA), both which contribute promotion. Surface biosorption...
The metagenomic approach was applied to characterize variations of microbial structure and functions in raw (RW) treated water (TW) a drinking treatment plant (DWTP) at Pearl River Delta, China. Microbial significantly influenced by the processes, shifting from Gammaproteobacteria Betaproteobacteria RW Alphaproteobacteria TW. Further functional analysis indicated basic metabolic microorganisms TW did not vary considerably. However, protective functions, i.e. glutathione synthesis genes...
Abstract The development of biofilms in drinking water (DW) systems may cause various problems to quality. To investigate the community structure on different pipe materials and global/specific metabolic functions DW biofilms, PCR-based 454 pyrosequencing data for 16S rRNA genes Illumina metagenomic were generated analysed. Considerable differences bacterial diversity taxonomic identified between formed stainless steel plastics, indicating that metallic facilitate formation higher biofilms....
We report the first integrated metatranscriptomic and metagenomic analysis of enhanced biological phosphorus removal (EBPR) sludge. A draft genome Candidatus Accumulibacter spp. strain HKU-1, a member Clade IB, was retrieved. It estimated to be ∼90% complete shared average nucleotide identities 83% 88% with finished CAP IIA UW-1 IA UW-2, respectively. Different from UW-1, phosphotransferase (pap) in polyphosphate metabolism V-ATPase orthophosphate transport were absent IB HKU-1....
Coprecipitation of Fe/Cr hydroxides with natural organic matter (NOM) is an important pathway for Cr immobilization. However, the role NOM in coprecipitation still controversial due to its molecular heterogeneity and diversity. This study focused on selectivity toward coprecipitates uncover fate via Fourier transform-ion cyclotron resonance-mass spectrometry (FT-ICR-MS). The results showed that significant effects Suwannee River (SRNOM) immobilization stability did not merely depend...
To explore the effect of different biochars on Cassia alata L. growth and heavy metal immobilization in multi-metal mine tailings, a 100-day pot experiment was conducted. Three derived from Hibiscus cannabinus core (HB), sewage sludge (SB) chicken manure (MB), were added to tailings at rates 0.4%, 1% 3% (w/w). The results showed that root biomass, shoot plant height length 1.2–2.8, 1.7–3.2, 1–1.5 1.6–3.3 times those control group, respectively. Pb, Zn, Cu, Cd As contents decreased by...
