US Patent:

8435772, May 7, 2013

Filed:

Mar 3, 2011

Appl. No.:

13/039494

Inventors:

Tony A. Hagen - Sioux Falls SD, US

International Classification:

C12P 7/10
C12P 7/08
A61K 36/00

US Classification:

435165, 435163, 424725

Abstract:

A nitrogen compound production method includes the step of establishing at least one aquatic plant in a cell containing water and alternating a step of inhibiting photosynthesis inducing light from reaching the at least one aquatic plant and a step of allowing photosynthesis inducing light to reach the at least one aquatic plant. The step of inhibiting photosynthesis inducing light defines a dark phase. A concentration of oxygen is reduced in the water to define an anoxic condition. During the anoxic condition, the at least one plant releases nitrogen compounds into the water and these nitrogen compounds are collected from the water contained in the cell.

Abstract:

A method of stimulating ethanol production and growth of aquatic plants includes the steps of placing aquatic plants in a cell containing water and creating an oxygenated condition within the cell to initiate an aerobic process. The aquatic plants create and store carbohydrates during the aerobic process. The cell is then covered with a light blocking cover during the anoxic condition to inhibit light from entering the cell. An anoxic condition is created within the cell to initiate an anaerobic process by the aquatic plants. The aquatic plants increase in size and release ethanol into the water by metabolism of stored carbohydrates during the anaerobic process. The ethanol is then sequestered from the water.

Appl. No.:

12/437333

Inventors:

Tony A. Hagen - Sioux Falls SD, US

International Classification:

C12P 7/10

US Classification:

435165

Abstract:

A method of stimulating ethanol production and growth of aquatic plants includes the steps of placing aquatic plants in a cell containing water and creating an anoxic condition within the pool to initiate an anaerobic process by the aquatic plants. The aquatic plants increase in size and release ethanol by metabolism of stored carbohydrates during the anaerobic process. An oxygenated condition is then created within the cell to initiate an aerobic process. The aquatic plants create and store carbohydrates during the aerobic process. The steps of creating anoxic and oxygenated conditions are repeated to stimulate increased aquatic plant size and to increase the release of ethanol.

Appl. No.:

12/940491

Inventors:

Tony A. Hagen - Sioux Falls SD, US

Assignee:

AQUATECH BIOENERGY LLC - Sioux Falls SD

International Classification:

C12P 7/06

US Classification:

435161

Abstract:

Methods and systems for collecting, purifying, and/or extracting ethanol produced during anaerobic metabolism by aquatic plants is provided. The system includes a cell containing water and an aquatic plant, an ethanol extraction assembly in fluid communication with the cell for removing ethanol from the water. Ethanol is released by the aquatic plant by initiating an anaerobic process in the plant such as by regulating the photosynthesis inducing light that reaches the aquatic plant.
