Microbial mats are natural heterotrophic and autotrophic communities dominated by cyanobacteria (blue-green algae). They are self-organized laminated structures annealed tightly together by slimy secretions from various Microbial components. The surface slime of the mats effectively immobilizes the ecosystem to a variety of substrates, thereby stabilizing the most efficient internal microbial structure. Constructed microbial mats can be generated rapidly by enriching a water surface with ensiled grass clippings. These constructed mats are durable, tolerant to a variety of toxins and resilient under changing environmental conditions. The mats can he designed for specific tasks by inoculating the cyanobacteria/silage with selected microorganisms. Mats constructed with specific microbial components have been developed for various bioremediation applications: removal of metals, organic degradation, treatment of mixed contaminants, biological treatment ponds, and soil remediation. Constructed mats offer a broad range of mechanisms related to the sequestration of heavy metals, the biodegradation of recalcitrant organic compounds, and the remediation of mixed organic/inorganic contaminants such as TCE and carbofuran with heavy metals.
