Patent number: 8273248Abstract: A method for separating neutral lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting neutral lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal neutral lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. The neutral lipids are removed after first removing a polar lipid fraction and a protein fraction. These neutral lipids can be used to generate renewable fuels as well as food products and supplements.Type: GrantFiled: June 18, 2012Date of Patent: September 25, 2012Assignee: Heliae Development, LLCInventor: Aniket Kale

Patent number: 8262912Abstract: Bioactive compounds extracted from a fermentation broth created by a unique microbial community during a fermentation process and fractionated into several fractions based on size. Four of the resulting fractions stimulate growth of plants that are planted in soil to which the fractions have been applied. The fractions can be applied to the soil individually or combined together prior to application. In another embodiment, the unique fractions can be freeze dried or spray dried.Type: GrantFiled: June 5, 2009Date of Patent: September 11, 2012Assignee: Tenfold Technologies, LLCInventors: David P. Lanciault, Robert N. Ames

Process and apparatus for separating and recovering waste alkali from cyclohexane oxidation solution
Patent number: 8221634Abstract: A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.Type: GrantFiled: January 22, 2009Date of Patent: July 17, 2012Assignee: East China University of Science and TechnologyInventors: Zhishan Bai, Zhuoqun Qian, Ji Ma, Ping Zhou, Yanhong Zhang, Hualin Wang -
Patent number: 8211308Abstract: A method for separating polar lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting polar lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal polar lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. These polar lipids are high value products which can be used as surfactants, detergents, and food additives. Neutral lipids remaining in the algal biomass after extraction of polar lipids can be used to generate renewable fuels.Type: GrantFiled: November 1, 2011Date of Patent: July 3, 2012Assignee: Heliae Development, LLCInventor: Aniket Kale

Patent number: 8211309Abstract: A method for separating proteins from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting proteins from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal proteins from a wet algal biomass. These proteins are high value products which can be used as renewable sources of food and food additives. Neutral lipids remaining in the algal biomass after extraction of proteins can be used to generate renewable fuels.Type: GrantFiled: November 1, 2011Date of Patent: July 3, 2012Assignee: Heliae Development, LLCInventor: Aniket Kale
