Images: Iron Mountain microbial biofilm
Caption: Microbial biofilm yields community genomes and metabolic clues. Examining life extracted from toxic runoff at a northern California mine, researchers for the first time have reconstructed multiple individual genomes from a microbial community taken from an environmental sample rather than from a laboratory culture.
