Microbial Community Composition of Mine Wastes in Cornwall and West Devon (UK)

摘要

Mine wastes and control soils from twelve sites around Cornwall and West Devon (UK) were analysed for microbial community structure, pH and readily extractible metals (an indication of mobility). About 70% of total diversity observed was constituted by six phyla (Acidobacteria, Chloroflexi, Planctomycetes, Proteobacteria, Verrucomicrobia, and candidate division AD3). Microbial community structure revealed patterns of distribution that mostly differed between waste samples and controls. Cluster analysis of the geochemical data (pH and readily extractible metals) indicated the presence of four groups; two groups of controls and two of samples defined by similar features. pH appeared to correlate with the portion of shared community.
