International Classification:

US Classification:
435 41, 4352921, 4352871, 4352861
Abstract:
Disclosed is a culture system for the production of algae biomass to obtain lipid, protein and carbohydrate. By integrating heterotrophic processes with a phototrophic process in parallel, this system provides year around production in colder climates. By integrating heterotrophic processes with a phototrophic process in series, this system creates a two-stage, separated mixed-trophic algal process that uses organic carbon and nutrients for the production of seed in the heterotrophic process, followed by release of cultured seed in large-scale phototrophic culture for cell biomass accumulation. Organic carbon source including waste materials can be used to feed the heterotrophic process. The production capacity ratio between the heterotrophic and the phototrophic processes can be adjusted according to season and according to the availability of related resources. The systems are used for producing and harvesting an algal biofuel feedstock as well as other potential high-value products. The sequence and approach enhances utilization of carbon and nutrient waste-streams, provides an effective method for controlling contamination, adds flexibility in regard to production and type of available products, and supplies greater economic viability due to maximized use of available growth surface areas.

International Classification:
C12M 1/00, C05F 11/00, C12P 19/04, C12P 7/64, C12P 23/00
US Classification:
71 23, 435134, 435 67, 435101, 4352891, 4353031
Abstract:
The feasibility of using COfrom a concentrated source to grow microalgae is limited by the high cost of COcapture and transportation, as well as significant COloss during algae culture. Another challenge is the inability of algae in using COduring night while COis continuously produced from the source. To address these challenges, this invention provides a process in which COis captured as bicarbonate and used as feedstock for algae culture. Then the carbonate is regenerated in the algae culture process as absorbent to capture more CO, which is converted to bicarbonate for use as feedstock, etc. This process significantly reduces carbon capture costs since it avoids the energy for carbonate regeneration. Also, transporting a solid or aqueous bicarbonate solution has a much lower cost than transporting compressed CO, and using bicarbonate provides a better alternative for COdelivery to algae culture systems than supplying COgas.

International Classification:
C12P 5/02
US Classification:
435167, 4352941
Abstract:
Low cost, efficient two-stage anaerobic digestion systems for the production of biogas (e.g. methane) are provided. During the first stage, biogas is produced in a first reactor by anaerobic microbes cultured in two phases: a high solids phase and a low solids phase. During the second stage, biogas is produced in a second reactor by a methanogen-rich anaerobic culture cultured in low solids medium. Removal of effluent comprising pH lowering reaction products assists in maintaining a suitable pH in the high solids phase. The transfer of effluent from the second reactor to the first reactor assists in maintaining a suitable pH in the high solids phase, in mixing of the high solids phase, and in reseeding the high solids phase with methanogens. Methane is produced in and recovered from both reactors.

Abstract:
Particular aspects provide a method for recovering phosphate, comprising: obtaining an effluent or wastewater, etc. having calcium-sequestered phosphate; adding to the effluent or wastewater a calcium chelating or sequestration agent suitable to chelate or sequester Ca ions from the calcium-sequestered phosphate to facilitate release of phosphate from the calcium-sequestered phosphate; transferring, facilitated by said Ca ion capture and in the presence of sufficient concentrations of NH and Mgions, of the phosphate into struvite (magnesium ammonium phosphate hexahydrate or MgNHPO. 6HO), or hydrated magnesium ammonium complex of phosphate; and recovering the struvite, or the formed hydrated magnesium ammonium complex. Preferably, the method further comprises acidification of the effluent or wastewater to facilitate release of Ca ions from the calcium-sequestered phosphate and chelation of sequestration of the Ca ions by the calcium chelating or sequestration agent. Additional aspects provide a phosphate-containing fertilizer comprising struvite, and methods for making same.

International Classification:
C12P 7/64
US Classification:
435134
Abstract:
A multiphase culturing process for high density heterotrophic microalgal growth uses crude glycerol as the primary carbon source and produces ω-3 fatty acids. The process uses multiphase growth conditions that decouple the phases of increasing cell density and increasing cell size and fatty acid production. The entire process is integrated with biodiesel production.

US Classification:
44313, 44451
Abstract:
A selective pyrolysis process for the production of bio-oils enriched in pyrolytic sugars and phenols and conversion of these compounds into second generation bio-fuels is disclosed herein. One embodiment of the process comprises pre-treating a biomass with superheated steam or gases in a selected range of temperatures, followed by fast pyrolysis using synthesis gas as a carrier, and a two-step condensation operation. The aqueous phase from the second condenser can then be reformed to produce hydrogen or can be gasified together with the charcoal to produce syngas.
