“…In the early stages of the restoration forest, fungi played a more important role in building the soil microbial network (Figure 4 and Table 1). The association of bacteria and fungi increased with increasing forest age, the bacterial‐fungal diversity network became simple and specialized, the products to be metabolized and decomposed in the soil decreased with increasing forest age, and the multiplicity of network relationships gradually increased with the singularity of nutrient substrates (Jiang et al, 2021; Zheng et al, 2021). Increasing the age of the trees did not increase the complexity of the microbial network, and those different ages possessed different microbiota, indicating that microbes were highly selected by apoplastic properties and reflecting that increasing stand age makes microbial decomposition of apoplastic material more specialized and efficient.…”

It is of great interest to elucidate the biogeographic patterns of soil microorganisms and their driving forces, which are fundamental to predicting alterations in microbial‐mediated functions arising from environmental changes. Although the vertical movement of dissolved organic matter (DOM) drives the cycle of nutrients such as soil carbon, in the restored ecosystem, the relationship between DOM and soil microbial nutrient utilization remains to be determined. Here, we investigated the changes of soil microbial community at 0–40 cm depth profile in three stages (10, 30, 50 years) of succession in Larix olgensis plantations and the fluorescence spectrum composition of DOM. With the increase of soil depth, the signal source of microorganisms increases. In a coniferous forest soil environment, the possible main source of DOM in deep soil is the production of microbial metabolism. Difficulty in the decomposition of organic matter determines the distribution and composition of microorganisms. Increasing forest age makes bacteria and fungi more specific and bacterial‐fungal associations greater. Overall, our work contributes to the understanding of factors underlying microbial community distribution in plantation forests and the importance of DOM quality in the building microbial community.

“…PCR was used to amplify the V5-to-V7 hypervariable regions of bacterial 16S rRNA genes. 16S rRNA gene amplification was performed using the forward primer 799F (5′- AACMGGAT - TAGATACCCKG -3′) and the reverse primer 1193R (5′- ACGTCATCCC - CACCTTCC -3′) ( 39 ). Paired-end sequencing (2 × 300 bp) of quality-validated samples was conducted on the Illumina Miseq platform using the MiSeq reagent kit V3 (600 cycles) ( 39 ).…”

“…The fungal communities were most dependent on soil moisture. The fungal community in soil is usually dominated by Basidiomycota and Ascomycota [45,46]. Fungi are described to be mainly influenced by the plant population of a site as well as water availability and other abiotic factors such as N-richness, carbon content, or soil quality [46][47][48][49].…”

Mortierellomycota are often found in heavy-metal-and radionuclide-contaminated, disturbed soil and they are known for accumulation of heavy metals such as Cd, Co, Hg, Ni, Zn, and U [6,50,51] Here, we could show Mortierellomycota in high abundances correlated with Sr and Cs gradients in a saline environment.…”

Biomineralization by Extremely Halophilic and Metal-Tolerant Community Members from a Sulfate-Dominated Metal-Rich Environment

The adaptation to adverse environmental conditions can lead to adapted microbial communities that may be screened for mechanisms involved in halophily and, in this case, metal tolerance. At a former uranium mining and milling site in Seelingstädt, Germany, microbial communities from surface waters and sediment soils were screened for isolates surviving high salt and metal concentrations. The high salt contents consisted mainly of chloride and sulfate, both in soil and riverbed sediment samples, accompanied by high metal loads with presence of cesium and strontium. The community structure was dominated by Chloroflexi, Proteobacteria and Acidobacteriota, while only at the highest contaminations did Firmicutes and Desulfobacterota reach appreciable percentages in the DNA-based community analysis. The extreme conditions providing high stress were mirrored by low numbers of cultivable strains. Thirty-four extremely halotolerant bacteria (23 Bacillus sp. and another 4 Bacillales, 5 Actinobacteria, and 1 Gamma-Proteobacterium) surviving 25 to 100 mM SrCl2, CsCl, and Cs2SO4 were further analyzed. Mineral formation of strontium- or cesium-struvite could be observed, reducing bioavailability and thereby constituting the dominant metal and salt resistance strategy in this environment.
