Abstract
Background
The Allchar mine situated in southern part of the Republic of North Macedonia, is an unique mine well known as the source of the lorandite (TlAsS2) that present mineral with purest contain of thallium (Tl) in the world. The Crven Dol mine, part of the Allchar mine complex, holds an estimated 500 t of Tl. As a result of interaction of solar neutrinos with 205Tl of the lorandite, Tl transforms to 205 Pb (205 lead whose 15,3 million years half-life present traps of neutrino capture event). Lorandite from this ore deposit is used as geochemical detector to capture neutrinos from the Sun, developed in the project LOREX).
Objectives and Methods of this study was, for the first time for this locality, to evaluate presence and diversity of bacteria and fungi using metagenomic methods and bioinformatic analysis (Krona viewer).
Results showed high bacterial and fungal diversity.
Most dominant bacterial phyla level were: Proteobacteria, Bacteroidetes, Acidobacteria, Planctomycetes, Actinobacteria, and Verrucomicrobia. On the genus level following groups of bacteria were detected: Chryseolinea, Opitutus, Flavobacterium, Pseudomonas, Terrimonas and Sphingomonas.
Fungi phyla Ascomycota (genera: Pilidium, Dendroclathra, Rosellinia and Hypomyces) and Basidiomycota (genera: Coprinellus and Coprinus) were confirmed.
This study is the first to identify specific As- and Tl- tolerant fungal (Pilidium, Cladophialophora, Neobulgaria, and Mycena) and bacterial genera
(Trichococcus, Devosia, Litorilinea, and Gimesia).
ICP-OES analysis of the samples detected 25 elements and high concentration of As and Tl.
Keywords: Allchar, mine, bacteria, fungi, diversity, lorandite, thallium.
