“…Soil microorganisms play an essential role in soil fertility, carbon and nitrogen cycling, and organic matter decomposition ( Joa et al, 2014 ). Mycorrhizal fungi, such as arbuscular mycorrhizal and ectomycorrhizal fungi, can form mutually beneficial symbiotic relationships with plants, improve nutrient acquisition with their hyphal network, and enhance plant resistance ( Akib et al, 2019 ). Furthermore, saprotrophic fungi have been reported to play roles in biodegradation or transformation of organic and inorganic pollutants through enzymatic degradation, biochemical or physical immobilization mechanisms, and increasing the availability of soil nutrients ( Jennifer et al, 2013 ; Ito et al, 2020 ).…”

Fairy ring is a natural phenomenon in which fungal fruiting bodies occur as a ring on a spot. This ring is produced due to spore ejection by Basidiomycetous fungi and forms a lush growing plant belt. However, the drivers for such formations and the potential plant growth-promoting rhizobacteria in fairy ring soils remain unknown. Fairy rings formed by Leucocalocybe mongolica were selected in this study. Soil characteristics and microbial (bacteria and fungi) community structures between beneath and outside the fairy rings were compared through high-throughput sequencing. Beneficial bacterial resources were excavated using dependent culturable methods. Soil electrical conductivity and available potassium were higher in the soil beneath the ring than outside it. These parameters were positively correlated with the dominant microbial community, but microbial diversity was lower. In the soil beneath the fairy ring, Bacteroidetes and Basidiomycota were more abundant, whereas Verrucomicrobia was less prevalent. Bacillus pumilus (strain BG-5) was isolated from the soil beneath the ring. Strain BG-5 can solubilize phosphorus and produce indole-3-acetic acid, NH4+, and siderophores. Furthermore, strain BG-5 enhanced salt tolerance and promoted the growth of Arabidopsis thaliana, wheat (Triticum aestivum), and cotton (Gossypium hirsutum) seedlings. This study indicated the presence of abundant beneficial microbes driving the flourishing growth of plants in the fairy ring soil and provided bio-resources for agricultural growth-promoting agents.

This study aimed to determine the types of fungi that can provide information on microbes associated with the post-mining forest land area of PT. Vale Indonesia. This study used a descriptive method by recording and describing the phenomena obtained. Sampling in the field was done by taking 500 g of soil/point (with three replications). Soil samples were taken around the roots or rhizosphere areas with 10 - 30 cm depth in natural and reclamation forest areas. Isolation of microbial growth was conducted by using the dilution technique. The purification of the obtained isolates was carried out by inoculation in PDA media with the point method, then incubated for ± 5 days at 27°C, and their growth was observed. Characterization of microscopic fungi isolates was identified based on the characteristics of the morphological structures. Based on preliminary research results of fungi soil samples originating from reclamation and natural forest areas, 11 rhizosphere fungi isolates were obtained. The fungi colonies’ color at the top and bottom had various colors and different textures. Greenish and whitish colors dominated the colony color, but some isolates had white, brown, cream, gray, yellowish, whitish, greenish colors, and some had spots. Colony texture was dominated by velvet, but some isolates had the texture of fine cotton and coarse cotton, presumably Aspergillus niger, Aspergillus sp, Fusarium oxysporum, Pénicillium sp., Trichoderma harzianum, and Trichoderma viride. This research will be continued to ascertain the type and function of each isolate.
