Patent number: 8187861Abstract: For extracting phosphorous from algae-in a body of water, the algae are deposited into a sealable tank (200) that is then evacuated, thereby rupturing the algal cell walls. The ruptured algae are then moved to a second tank (260), mixed with water and bacterial cultures, and allowed to settle until the lipids rise to the top and the oil-less debris settles to the bottom. The second tank also contains sacrificial (295) and rusted electrodes (320). The phosphorous from the algae combines with the rust. The lipids and debris are then removed. Next, an electrical source (315) causes the rust to be removed from the rusted electrodes and settle. In addition, a phosphorous-rich scum floats to the top. These components are placed in storage containers for later use and the water is returned, thereby reducing its phosphorous content.Type: GrantFiled: February 26, 2010Date of Patent: May 29, 2012Inventor: Allen John Schuh

Patent number: 8008061Abstract: Most microalgae are obligate photoautotrophs and their growth is strictly dependent on the generation of photosynthetically-derived energy. In this study it is shown that the microalga Phaeodaclylurn tricornutum can be engineered to import glucose and grow in the dark through the introduction of genes encoding glucose transporters. Both the human and Chlorella kessleri glucose transporters facilitated the uptake of glucose by P. tricornutum, allowing the cells to metabolize exogenous organic carbon and thrive, independent of light. This is the first successful trophic conversion of an obligate photoautotroph through metabolic engineering, and it demonstrates that methods of cell nourishment can be fundamentally altered with the introduction of a single gene. Since strains transformed with the glucose transport genes are able to grow non-photosynthetically, they can be exploited for the analysis of photosynthetic processes through mutant generation and characterization.Type: GrantFiled: August 21, 2007Date of Patent: August 30, 2011Assignee: Martek Biosciences CorporationInventors: Kirk Emil Apt, F.

Patent number: 7022509Abstract: A method for removing a gas from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the compound to be removed into the gas vesicles, and placing the gas vesicles such that the gas compound is removed from the site. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium—such as darkness, exponential growth stage, flocculation, or dissolved gas flotation—then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: May 10, 2002Date of Patent: April 4, 2006Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap

Patent number: 6566123Abstract: A biomass containing the microflora of the order Thraustochytriales preferably, Thraustochytrium, Schizochytrium, and mixtures thereof, is prepared by growing the microflora in a fermentation medium containing less than about 3 grams of chloride per liter of the cultural medium and a non-chloride containing sodium salts, in particular sodium sulfate. In a preferred embodiment, the process produces microflora having a cell aggregate size less than about 150 microns useful for the production of food products for use in aquaculture. Further disclosed is a food product which includes Thraustochytrium, Schizochytrium, and mixtures thereof, and a component selected from flaxseed, rapeseed, soybean and avocado meal. Such a food product includes a balance of long chain and short chain omega-3 highly unsaturated fatty acids. The lipids containing these fatty acids can also be extracted and used in nutritional, pharmaceutical and industrial applications.Type: GrantFiled: August 15, 2000Date of Patent: May 20, 2003Assignee: Martek Biosciences Boulder CorporationInventor: William R.

Patent number: 6551596Abstract: Chlorella fractionated extracts containing high molecular weight Chlorella polysaccharide and polysaccharide complexes show immune modulatory, specifically immune stimulatory activity. The fractionated extracts are obtained by size fractionation of an extract of Chlorella and selecting fractions containing high molecular weight polysaccharides and polysaccharide complexes of about 1×104 Da to about 1×107 Da. A fraction of about 4×106 Da to about 1×107 Da is preferably obtained by size fractionation. The polysaccharide and polysaccharide complexes contain glucose and any combination of: galactose, rhamnose, mannose and arabinose, as well as N-acetyl glucosamine and N-acetyl galactosamine. The extracts may be treated with pronase, DNAse, RNAse and proteases to remove unassociated nucleic acids, ribonucleic acids and proteins.Type: GrantFiled: August 10, 2001Date of Patent: April 22, 2003Assignee: Ocean Nutrition Canada LimitedInventor: Jaroslav A.

Patent number: 6465240Abstract: A method is provided for treating a waste stream by contacting the waste stream sequentially with a consortium of prokaryotic microorganisms, preferably purple non-sulfur bacteria, followed by a the green algae Chlorella. The consortium of prokaryotic microorganisms assimilate a first portion of the wastes, and the green algae assimilate the remaining portion of the wastes to produce a substantially purified effluent stream. Isolated microorganisms made by the above method are valuable commercial products.Type: GrantFiled: December 11, 1998Date of Patent: October 15, 2002Assignees: Biotechna Environmental International, Ltd.Inventors: Howard M.

Patent number: 6413763Abstract: A method for removing a gas compound from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the gas compound to be removed into the gas vesicles, and placing the gas vesicles contacted with a medium such that the gas compound is removed from the site to the medium. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium. Then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.Type: GrantFiled: January 21, 2000Date of Patent: July 2, 2002Assignee: The University of AkronInventors: Lu-Kwang Ju, Anand Sundararajan, Sunil Kashyap

Patent number: 6156561Abstract: A system and method for its use for efficiently culturing algae such as Spirulina are provided. The system comprises a culture pool for exposing a culture fluid containing the algae to sunlight, a culture tank having a larger depth than the culture pool, which is disposed adjacent to the culture pool, a supply unit for supplying the culture fluid from the culture pool to the culture tank, and at least one filter for removing grown algae from the culture fluid overflowing from the culture tank to the culture pool, while allowing to return a filtrate containing immature algae to the culture pool. It is preferred that this system further comprises a unit for mixing a gas containing carbon dioxide in the culture fluid to be supplied in the culture tank, and a lighting unit disposed in the culture tank to provide an artificial light to the culture fluid. In this case, it is possible to carry out the photosynthesis of the algae night and day.Type: GrantFiled: July 17, 1998Date of Patent: December 5, 2000Assignee: Spirulina Biological Lab., Ltd.Inventors: Keiun Kodo, Yasumasa Kodo
