Compositions and methods of biologically cemented structures for marine applications
The invention is directed to kits, compositions, tools and methods for biologically cemented structures. More particularly, the invention is directed to materials and methods for the farming of bivalves, such as oysters and clams, and also other marine and fresh water invertebrates such as sponges, and other commercially worthwhile sessile organisms. The kits, compositions, tools and methods of the invention are also applied to erosion control of beaches and underwater surfaces, for the formation of foundations such as footings for pier supports, marine walls and other desirable structures.

13. A method for the manufacture of a fabric comprising:
providing a fabric;
contacting the fabric with spores of urease-producing bacteria;
contacting the fabric with a chemical attractant, a nutrient and/or another organic or inorganic material that promotes growth and/or development of an organism; and
placing the fabric in an aqueous solution containing a nitrogen source and a calcium source.
14. The method of claim 13 , wherein the fabric comprises jute, hemp, sisal, burlap, paper, wood, plastic, a polymer, or a combination thereof.

17. The method of claim 13 , further comprising culturing the fabric with sessile organisms.
18. The method of claim 17 , wherein the sessile organisms are polyps or larval forms of clams, oysters, coral and/or sponges.
19. The method of claim 17 , wherein the fabric containing bacteria and sessile organisms is placed in an aqueous marine environment for a period of time to allow the sessile organisms to grow and develop.
20. A method of farming organisms comprising:
providing the fabric of claim 1 ;
placing the fabric in an aqueous solution containing a nitrogen source and a calcium source;
placing the fabric in an aqueous environment for a period of time; and
collecting organisms that are attracted to or adhere to the fabric.
21. The method of claim 20 , wherein the organisms are sessile organisms.

the fabric of claim 1 ;
spores of urease-producing cells, urease-producing cells, and/or urease enzymes, and polyps or larval forms of sessile organisms.
24. A method of erosion control or prevention comprising:
providing the fabric of claim 1 ;
contacting the fabric to an object in an aqueous solution containing a urea source and a calcium source; and
incubating the fabric for a period of time to produce calcite on and/or within the fabric thereby controlling or preventing erosion of the object and/or of area surrounding the object.
