Patent number: 9434962Abstract: Disclosed is an integrated process comprising first and second biotechnical processes. The first process produces biofuel and/or starting material for biofuel and uses a microorganism capable of producing enzymes. The second process produces biofuel and/or starting material for biofuel. In the integrated process, the microorganisms are cultivated and biofuel and/or starting material for biofuel and enzymes are produced. The microorganism culture, supernatant or a protein enriched fraction or a dilution of the supernatant comprising catalytically active enzyme(s) are introduced into the first and/or into the second process, or feedstock for the process(es) is treated. The invention relates also to use of the produced enzymes in biofuel production process or in other applications as an enzyme preparation or a source of enzymes. The invention relates also to use of the produced lipids and alcohols as biofuel, a component of biofuel or a starting material for biofuel production.Type: GrantFiled: December 21, 2011Date of Patent: September 6, 2016Assignee: Neste OyjInventors: Perttu Koskinen, Reijo Tanner

Patent number: 8936655Abstract: The present invention relates to an integrated process, which comprises a single cell oil production process, and a pulp and/or paper industry process. The process comprises that in the single cell oil production process is used a microorganism capable of producing lipids or lipids and enzymes when cultivated on a medium comprising organic material from pulp and/or paper industry. Lipids or lipids and enzymes are produced by said microorganisms in the single cell oil production process and/or in a process connected into it. The present invention relates also to use of lipids produced in the process as biofuel or as a component of biofuel or as a starting material for biofuel production and use of enzymes produced in the lipid production process in pulp and/or paper industry or in other applications as an enzyme preparation or as a source of enzymes.Type: GrantFiled: December 21, 2011Date of Patent: January 20, 2015Assignee: Neste Oil OyjInventors: Perttu Koskinen, Reijo Tanner

Patent number: 8845765Abstract: A method for recovering lipids from microbial biomass, the method including providing wet microbial biomass which contains lipids to extraction without disrupting the biomass cell walls, and subsequently, extracting the wet microbial biomass with a liquid extractant at elevated temperature of at least 170° C. and elevated pressure. The combination of the temperature and pressure is such that the lipids in the cells are contacted with the extractant. Subsequently the extracted lipids are recovered from or with the extractant.Type: GrantFiled: November 8, 2011Date of Patent: September 30, 2014Assignee: Neste Oil OyjInventors: Annika Malm, Reijo Tanner, Mervi Hujanen

Patent number: 8648210Abstract: The present invention relates to a method for purification of lipid material originating from biological material. In the method the lipid material comprising acylglycerols and phosphorus impurities and at least one added nonpolar solvent and at least one added polar solvent is provided into a reaction zone whereby at least a two phase system comprising a nonpolar phase and a polar phase is formed. The phase system is heated in the closed reaction zone under mixing at a temperature from 150° C. to 300° C. and at a pressure wherein said solvents are in subcritical state, preferably of below 100 bar, dependent on the vapor pressure of the selected solvents, until the phosphorus impurity is removed from the polar phase. Subsequently, the nonpolar phase including the purified oil comprising acylglycerols is separated and recovered from said phase system.Type: GrantFiled: May 27, 2011Date of Patent: February 11, 2014Assignee: Neste Oil OyjInventors: Mervi Hujanen, Annika Malm, Reijo Tanner
