The Allchar mineral mine is one of the oldest arsenic–antimony mines in the Republic of North Macedonia. The mine is a well-known reservoir of the worldwide purest source of the thallium-bearing mineral, lorandite (TlAsS2). The current study evaluated the bacterial and fungal diversity of three As- and Tl-contaminated sites in Allchar mineral mine. We used a combination of high-throughput sequencing and bioinformatic analyses. Trace metal content was detected using inductively coupled plasma optical emission spectrometry. Our analysis showed the presence of 25 elements and confirmed a high concentration of As and Tl. Alpha diversity indices suggested a high diversity and evenness of bacterial and fungal communities. Bacterial phyla that dominated the environment were Bacteroidetes, Acidobacteria, Planctomycetes, Actinobacteria and Verrucomicrobia. Looking at the genus level, we found the following groups of bacteria: Chryseolinea, Opitutus, Flavobacterium, Pseudomonas, Terrimonas, Sphingomonas and Reyranella. For the fungi genera, we report Tetracladium sp., Coprinellus micaceus, Coprinus sp. from Ascomycota and Basidiomycota phyla in all sites. We also observed a high abundance of the fungal species Pilidium sp., Dendroclathra lignicola, Rosellinia desmazieri, Hypomyces rosellus and Coprinellus disseminatus. This study is the first to identify specific As- and Tl-tolerant fungal (Pilidium sp., Cladophialophora sp., Neobulgaria sp. and Mycena acicula) and bacterial (Trichococcus, Devosia, Litorilinea and Gimesia) genera from Allchar mine, suggesting bioremediation and industrial potential.

北马其顿共和国'Allchar'方铁矿(TlAsS2)的细菌和真菌多样性。

Allchar矿山是北马其顿共和国最古老的砷锑矿之一。该矿山是世界上最纯的含th矿物,lo石(TlAsS 2)。当前的研究评估了Allchar矿山中三个被As和Tl污染的地点的细菌和真菌多样性。我们结合使用了高通量测序和生物信息学分析。使用电感耦合等离子体发射光谱法检测痕量金属含量。我们的分析表明存在25种元素,并确认了高浓度的As和Tl。Alpha多样性指数表明细菌和真菌群落具有高度多样性和均匀性。支配环境的细菌门是拟杆菌,酸性细菌,放线菌,放线菌和疣状微生物。从属水平来看,我们发现了以下细菌群:金线虫,异位杆菌,黄杆菌,假单胞菌,特里莫纳斯,鞘氨醇单胞菌氏菌。对于真菌属,我们报告了四角藻属(Tetracladium sp。),拟粉菌(Coprinellus micaceus),拟粉菌(Coprinus sp。)。在所有部位都来自Ascomycota和Basidiomycota phyla。我们还观察到了丰富的真菌物种菌毛菌属(Pilidium sp。),毛齿树(Dendroclathra lignicola),玫瑰蔷薇(Rosellinia desmazieri),玫瑰菌(Hypomyces rosellus)粉虱(Coprinellus disseminatus)。这项研究是第一个确定具体的AS-和TL宽容真菌(Pilidium属,Cladophialophora属,Neobulgaria属和菇acicula)和细菌(Trichococcus,Devosia,LitorilineaGimesia)属Allchar矿山,表明其生物修复作用和工业潜力。
