Abstract

Biofilms and microbial mats can be regarded as among the most vigorous and ancient ecosystems found on Earth (Noffke et al., 2006). In contrast with planktonic microbes, the extracellular polymeric substance in which they are usually embedded renders the microbes in biofilms relatively resilient to adverse environmental changes (Costerton and Stoodley, 2003). Biofilms are usually multilayered and involve consortia of microbes, in which all the materials needed to sustain life can be recycled (Stolz, 2003). A viable microbial mat is therefore quite likely to contain a mixture of autotrophic fixers of carbon dioxide, heterotrophic consumers that feed by ingestion of organic particles, and others that have adapted to recycle the preformed organic matter by means of enzymatic digestion and absorption through the cell wall – called osmotrophy.
