Algae Culture Patents (Class 47/1.4)
  • Patent number: 9540604
    Abstract: A method includes identifying a chlorophyll concentration/optical density (CCpOD) value using a chlorophyll concentration measurement of an autotroph culture and an optical density measurement of the autotroph culture. The method also includes identifying a change in the autotroph culture using the CCpOD value. The change in the autotroph culture can be identified by determining whether the CCpOD value falls outside upper and lower control limits. The upper and lower control limits can be identified using a specified number of previously-determined CCpOD values, which can be calculated when the autotroph culture is in a known healthy state. Multiple CCpOD values can be calculated, and an alarm can be generated if a specified number of the CCpOD values (such as one or more) fall outside the upper and lower control limits.

    Abstract: A simple alternative to separate filamentous bodies of Monostroma latissimum algae (large green algae) as seed stock. The filamentous bodies are easily separated and prepared for cultivation. At low luminosity (50 ?m mole s?1m?2), the filamentous bodies grow into the filamentous colony. If the filamentous colony is in turns irradiated at the luminosity greater than 100 ?m mole s?1m?2, it is turning into fronds. Thereby the filamentous bodies are evenly distributed into small segments so as to penetrate through the cotton rope for algal mass cultivation and further grow into fronds at high luminosity.

    Abstract: A light pipe for use in aqueous environments comprising an optical rod capable of total internal reflection, and disposed in the optical path of a light source such as a light emitting diode or other source. The optical rod has frosted and unfrosted portions, such that the light is propagated distally along the rod at the unfrosted portions, but a portion of the light is coupled out of the rod into the aqueous environment at each of the frosted portions. The relative sizes of the frosted portions are arranged so that substantially the same light power is coupled out of the rod at each frosted section, thus facilitating rapid and uniform growth of algae in the aqueous environment.

  • Patent number: 8790913
    Abstract: A pneumatic bioreactor includes a vessel containing a fluid to be mixed and at least one mixing device driven by gas pressure. A first embodiment includes a floating impeller that rises and falls in the fluid as gas bubbles carry it upward to the surface where the gas is then vented, permitting the impeller to sink in the fluid. The floating impeller may be tethered to a second impeller with a flexible member and pulley. The mixing speed is controlled with electromagnets in the vessel acting upon magnetic material in the impeller or its guides. In another embodiment, floating pistons mix the fluid, pushing it through a mixing plate with one or more apertures. In a third embodiment, the mixing device is a rotating drum with bubble-catching blades and rotating mixing plates with apertures. The top of the vessel for these mixers may include a closed top and sterile filters.

  • Patent number: 8785175
    Abstract: Systems and methods that facilitate the creation and harvesting of algae using tufted products. One exemplary tufted product comprises a substrate and tufts tufted through the substrate. The use of a tufted product provides various advantages with respect to the creation and harvesting of algae. Among other things, such products can be configured to improve the amount of algal-growing surface area provided and other growing environment characteristics and to facilitate the harvesting of the algae from the tufted product by facilitating the release of all or most of the algae from attachment to the tufted product.

  • Patent number: 8769867
    Abstract: Systems, methods and media for generating fluid flow in an algae cultivation pond are disclosed. Circulation of fluid in the algae cultivation pond is initiated via at least one jet. The circulation of fluid generates a velocity of fluid flow of at least ten centimeters per second in the algae cultivation pond. A head is provided to the at least one jet that overcomes a head loss associated with the velocity of fluid flow of at least ten centimeters per second in the algae cultivation pond.

  • Patent number: 8759068
    Abstract: The system for fermentation using algae of the present invention includes a first reactor and a second reactor being in fluid communication with each other. A first valve placed between the first reactor and the second reactor controls the fluid connection between the reactors. A gas inlet, in fluid connection to the first reactor, is located at an end opposite the second reactor. A devolatization unit or cell lysis chamber is connected to the second reactor by a second valve. A biomass stream having gas, liquid and biosolids contents passes through the first reactor with gas. The biomass stream mixes and dissolves the gas in the reactors. The cellular structure of the biomass stream ruptures in the devolatization unit, allowing the processed materials, such as oil, gas, and biosolids, to be harvested for use.

  • Publication number: 20140154769
    Abstract: A production system includes a structure configured to house a light-activated biological pathway. The production system further includes an optical filter attached to the structure. The optical filter is configured to receive light, to reflect a first portion of the received light, and to transmit a second portion of the received light, wherein the first portion has a different wavelength from the second portion. The production system is further configured to position the light-activated biological pathway to receive the second portion of the receive light.

  • Publication number: 20140144074
    Abstract: A simple alternative to separate filamentous bodies of Monostroma latissimum algae (large green algae) as seed stock. The filamentous bodies are easily separated and prepared for cultivation. At low luminosity (50 ?m mole s?1m?2), the filamentous bodies grow into the filamentous colony. If the filamentous colony is in turns irradiated at the luminosity greater than 100 ?m mole s?1m?2, it is turning into fronds. Thereby the filamentous bodies are evenly distributed into small segments so as to penetrate through the cotton rope for algal mass cultivation and further grow into fronds at high luminosity.

  • Patent number: 8734649
    Abstract: A method of dewatering algae and recycling water therefrom is presented. A method of dewatering a wet algal cell culture includes removing liquid from an algal cell culture to obtain a wet algal biomass having a lower liquid content than the algal cell culture. At least a portion of the liquid removed from the algal cell culture is recycled for use in a different algal cell culture. The method includes adding a water miscible solvent set to the wet algal biomass and waiting an amount of time to permit algal cells of the algal biomass to gather and isolating at least a portion of the gathered algal cells from at least a portion of the solvent set and liquid of the wet algal biomass so that a dewatered algal biomass is generated. The dewatered algal biomass can be used to generated algal products such as biofuels and nutraceuticals.

  • Publication number: 20140137941
    Abstract: Solar-redshift systems comprise an integral array of redshift modules, each having at least a focusing device, a target, and a quantum-dot vessel. The quantum-dot vessel contains quantum dots that emit light having an emission wavelength. The focusing device directs incident solar radiation through a focusing gap and toward the quantum-dot vessel, or into a slab waveguide and then toward the quantum-dot vessel, causing the quantum dots to emit redshifted light having the emission wavelength. The redshifted light is directed to the target, examples of which include a photovoltaic material or a living photosynthetic organism. The target has increased sensitivity or response to photons having the wavelength of the redshifted light. A trapping reflector component of the quantum-dot vessel prevents loss of redshifted light to the environment outside the solar-redshift system and allows undesirable infrared light to be removed from the system.
