From: Thiothrix and Sulfurovum genera dominate bacterial mats in Slovak cold sulfur springs
Principal coordinate analysis (PCoA) based on the unweighted (A) and weighted (B) Unifrac distance matrices of two groups of samples obtained from five sulfur springs. Each plot represents the microbiota of one sample, samples are colored based on the location. Dots represent samples with DNA extracted by classical method, whilst triangles represent samples of DNA extracted employing a commercial isolation kit. The microbiota of each spring is significantly distinct (p = 0.003, PERMANOVA with 1000 permutations)
