Compositions and methods for producing materials for construction and for dust control utilizing enzyme producing cells, an amount of a nitrogen source such as urea, and an amount of calcium such as calcium chloride. Calcium contributes to the formation of calcium carbonate which creates a solid structure, layer or shield. Compositions of the invention can be sprayed or otherwise applied to surfaces for erosion control, foundation support, prevention of sink hole formation or other applications. Ammonia, water and other by-products of the process can be recycled and re-utilized for the same or other purposes including, for example, as fertilizers and energy sources, or independently fermented from selectively cultivated microorganisms. |
