  • Patent number: 9850555
    Abstract: The present application is generally directed to separation and recovery of rare earths using biomass, liposomes, and/or other materials. In some embodiments, a composition comprising rare earths is exposed to biomass, where some of the rare earths are transferred to the biomass, e.g., via absorption. The composition may then be separated from the biomass. A solution may be exposed to the biomass thereby enriching the solution in one or more rare earths, relative to other rare earths in the biomass. The solution and the biomass may then be separated, and the rare earths recovered from the solution. In some cases, this process may be repeated with different solutions, which may result in different solutions enriched in various rare earths. Similar processes may be used to separate the rare earths from thorium and uranium. Liposomes may be used instead of and/or in addition to biomass.

  • Patent number: 9441252
    Abstract: The present invention provides a cost effective biotechnological process for production of bio-fuels from isolated and characterized microalgae. The algal strains used in the present invention having higher biomass, higher lipid productivity, higher pH and temperature tolerance are selected from the group consisting of Chlorella vulgaris iOC-1, Chlorella vulgaris iOC-2, Chlorella kessleri, Botrococcus bruni, Dunaliella salina and Nannochloris oculat or a combination thereof having 95-100% similarity with 18s ribosomal nucleic acids nucleotide sequences (rDNA) given for Seq. ID I, Seq. ID 2, Seq. ID 3, Seq. ID 4, Seq. ID 5 and Seq. ID 6. The present process of bio-fuel production comprises the steps of producing lipid from green algae in bioreactors by various novel steps and extracting oil from dried algal cells and ultimately producing biodiesel by transesterification of the said extracted oil.

  • Patent number: 9416346
    Abstract: A method of damaging cell structure of an aquatic substance includes: providing an aquatic substance raw material, where the aquatic substance raw material includes an aquatic substance; adjusting a water content in the aquatic substance raw material to form an aquatic substance slurry to be processed; placing the aquatic substance slurry to be processed in a pressure container; introducing a compressed gas into the pressure container to enable the compressed gas and the water in the aquatic substance slurry to be processed to form an acidic fluid, and making the cell structure of the aquatic substance hydrolyzed and damaged by the acidic fluid; and performing a depressurizing step to separate the compressed gas.

  • Patent number: 9222065
    Abstract: The present invention relates to a method for photoculturing and harvesting microalgae, and more particularly to a method for photoculturing and harvesting microalgae, in which a light emitting diode (LED) is used as a light source to increase the efficiency with which microalgae are cultured, and the cultured microalgae are harvested using a natural polymer flocculant and air microbubbles so that the operating cost is reduced and the range of application of microalgae is expanded, and also a semi-continuous culture method is applied so that the maximum concentration of microalgae can be produced again within a short time, even though the amount of microalgae harvested is small.

  • Patent number: 9200235
    Abstract: A method and system for processing algae involves the use of an ionic liquid-containing clarified cell lysate to lyse algae cells. The resulting crude cell lysate may be clarified and subsequently used to lyse algae cells. The process may be repeated a number of times before a clarified lysate is separated into lipid and aqueous phases for further processing and/or purification of desired products.

  • Patent number: 9200244
    Abstract: The invention relates to a method for cultivating photoautotrophic micro-organisms, comprising the following steps: provision of a photosynthesis layer, which contains a photosynthesis medium and photoautotrophic micro-organisms suspended therein, in a closed accommodation space having a gas-diffusion-inhibiting outer boundary, wherein the photosynthesis layer has an average thickness of no more than 10 mm; exposure of the photosynthesis layer without eddying or feeding through a gas in the photosynthesis medium while limiting the diffusive gas exchange of the accommodation space by the environment, wherein the supply of micro-organisms in the photosynthesis medium with hydrogen carbonate ions is maintained by storing hydrogen carbonate ions in the photosynthesis medium and/or providing a photosynthesis substrate in the form of carbon dioxide and hydrogen carbonate from a cell-free carbon storage medium outside the photosynthesis layer; and conducting a gas formed during photosynthesis out of the accommodatio
