Abstract

A method is provided for extraction of chemical compounds from an organism having a cell wall that includes adding nanomaterials, which may be metallic nanofibers such as silver nanofibers, to the organism.

Claims (11)

1. A method of extracting a chemical compound from an organism having a cell wall, comprising:

a first step of exposing the cell wall of the organism to a solution of metallic nanomaterials such that the cell wall is disrupted;

a second step of treating the organism with an extraction solvent; and

extracting the chemical compound from the organism.

2. The method of claim 1 , wherein the metallic nanomaterials are silver nanofibers.

3. The method of claim 2 , wherein a concentration of the silver nanofibers in the solution of nanomaterials is approximately 1 ppm to approximately 1000 ppm.

4. The method of claim 3 , wherein a concentration of the silver nanofibers in the solution of nanomaterials is approximately 200 ppm to approximately 500 ppm.

5. The method of claim 4 , wherein the organism is exposed to the solution of silver nanofibers for approximately 2 minutes to approximately 30 minutes.

6. The method of claim 1 , wherein the organism is at least one of microalgae and cyanobacteria.

7. The method of claim 1 , further comprising: exposing the organism to at least one of heat, light, microwave, ultrasound, agitation and ultra violet energy.

8. The method of claim 1 , wherein the chemical compound is at least one of a lipid, a pigment, a protein, a carbohydrate, and a nucleic acid.
