“…A recent study from China (Li et al 2019) reported that the main dominant phyla in soil under tomato plants grown with groundwater irrigation were Proteobacteria, Acidobacteria and Actinobacteria, i.e. similar to the ones in our study with husk tomato.…”

“…similar to the ones in our study with husk tomato. However, the alpha-diversity indices of the husk tomato rhizosphere bacteriobiome are much higher, Shannon and Chao-1 being 7.5 and 5,000 vs. 1.9 and 21 (Li et al 2019), respectively. Yet in an earlier study in greenhouse pot experiment the estimated alpha-diversity indices for tomato rhizosphere bacteriobiome (Cai et al 2017) were 5.4 and 2,400, i.e.…”

The composition and structure of rhizosphere bacteriobiome of the husk tomato (Physalis philadelphica Lam.) plants grown on Phaeozem in the open field in West Siberia, Russia (55°15’ NL, 83°31’ EL) were studied using Illumina MiSeq sequencing of the V3-V4 hypervariable region of 16S rRNA genes. In total 5898 OTUs (Operational Taxonomic Units) were found in the study, representing 20 phyla and 53 identified and 15 non-identified (below the phylum level) classes. The most OTU-rich phyla were Proteobacteria, Acidobacteria and Actinobacteria, their relative abundance in the total number of sequence reads being 26, 22 and 19%, respectively. Bacteroidetes, Gemmatimonadetes and Verrucomicrobia phyla each accounted for 2 ‒ 4%. The rest 14 of the identified phyla were quite negligible, contributing less than 0.5% each. At the OTUs level, the structure was very even and equitable, as only 7 OTUs had relative abundance ranging from 0.5 to 1.1%. The main dominant OTU represented Bradyrhizobiaceae family, implying the importance of nitrogen-fixing bacteria for plant growth and development without any mineral fertilisation. The dominance biodiversity index was very low (0.001), while Shannon index was rather high (7.5). We believe the presented husk tomato rhizosphere bacteriobiome, as the first study using new generation sequencing platform for this species, will help get a better picture of Solanaceae microbiomes in different environments, thus contributing to a more comprehensive understanding of shaping microbial communities by plant roots.

“…Numerous studies have reported that phylum Proteobacteria is one of the most abundant phylum either in tailings and other extreme conditions due to its most metabolically versatile (Dhal & Sar, 2014;Shi et al, 2017). To the best of our knowledge, Proteobacteria, as one of abundant bacterial phylum in soil, plays a vital role in nutrient cycling (Kuffner et al, 2012;Li et al, 2019), which was positively correlated with C mineralization (Fierer, Bradford, & Jackson, 2007). Not similar to our results, the study in the gold mine tailings identified that Actinobacteria, as the predominant phylum, exhibits significant resilience to thrive in hostile environments (Sibanda, Selvarajan, Msagati, Venkatachalam, & Meddows-Taylor, 2019).…”

Response of soil environment factors and microbial communities to phytoremediation with Robinia pseudoacacia in an open‐cut magnesite mine

Overexploitation of magnesium has caused serious environmental pollution, and the ecological restoration of magnesite mines has attracted increasing attention in China. The aim of this study was to assess the effects of phytoremediation with Robinia pseudoacacia (RP) on soil quality and microbial communities in magnesite mines. Here, soil samples were collected from restored areas (R. pseudoacacia), natural forest (NF), and unrestored areas (CK), and the soil microbial communities were assessed by Illumina high-throughput sequencing. Phytoremediation with R. pseudoacacia could alleviate soil alkalization and contribute to the accumulation of soil nutrients. A total of 531,329 effective 16S rRNA and 596,344 valid Internal Transcribed Spacer rRNA gene sequences were obtained, which were classified into 30 bacterial and 12 fungal phyla. The predominant bacterial and fungal phyla were Proteobacteria and Ascomycota, respectively. Bacterial diversity indices of RP were higher than those of the CK, both of which were lower than those in the NF site. While, fungal Chao1 and ACE (abundance-based coverage estimator) indices of RP were higher than those of the CK and even surpassed those in the NF site. Soil microbial communities significantly differed among different treatments, and the effects of soil factors on microbial communities were comprehensive and not determined by a single factor. Generally, these results indicated that phytoremediation with R. pseudoacacia could effectively improve the soil environment of the abandoned magnesium mine, which provide useful insights and practical references for the suitable species that would be planted on magnesite mine for restoration.

“…Further, the time-dependent pathogen load estimated by the model, norovirus concentration in raw wastewater was consistent with data reported in the recent publications. Li, Zhang, et al (2019) and Li, Cao, et al (2019) investigated the use of reclaimed wastewater for irrigation and effects on the soil microorganisms. This study used a site that was used over forty years for irrigation with reclaimed water.…”

This paper presents the review of the literature published in the year 2019 related to treatment and reuse of wastewater and effects on the environment and human health. The scientific review on the treatment and reuse of wastewaters is divided into various sections in the paper. The review sections cover wastewater management, reuse, removal of microorganisms, and chemical constituents. Besides, the review also covers research focused on wastewater treatment plants, disposal, and the management of wastewater sludge as well as biosolids in the environment.
