Direct examination of microbial mats from Icelandic hot springs with transmission electron microscopy and energy-dispersive X-ray spectroscopy revealed a consortium of bacterial cells in varying stages of mineralization. Differences in observed mineralogy largely reflect differences in the chemistry of the hydrothermal waters. Silica-rich spheroids formed epicellularly on cell walls and surrounding sheaths and capsules of microorganisms and, in some cases, intracellularly when presumably the… CONTINUE READING
