20090011509 | INTEGRASE FUSION PROTEINS AND THEIR USE WITH INTEGRATING GENE THERAPY - In a method of targeting intergration of a transgene comprising retrovirus-like DNA into a eukaryotic genome, the genome is cleared by an endonuclease and the transgene is introduced at the site of cleavage, wherein the endonuclease is specific to a site in an abundant rDNA locus and is fused to an integrase that mediates the introduction of the transgene. The fusion protein may be new. | 01-08-2009 |

20120110898 | METHOD FOR LIPID EXTRACTION FROM BIOMASS - 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. | 05-10-2012 |
20120116103 | Method for Purifying Lipid Material - 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. Sub-sequently, the nonpolar phase including the purified oil comprising acylglycerols is separated and recovered from said phase system. | 05-10-2012 |
20120116105 | METHOD FOR RECOVERY OF OIL FROM BIOMASS - A method and apparatus for recovery of lipids from microbial biomass, including providing wet microbial biomass to thermal pretreatment of at least 100° C. in a pressure vessel, subjecting the thermally pretreated microbial biomass to extraction using a liquid hydrocarbon as an extractant, and subsequently, recovering a product containing lipids. | 05-10-2012 |
20130090502 | PROCESS FOR MANUFACTURE OF LIQUID FUEL COMPONENST FROM RENEWABLE SOURCES - A method for producing liquid fuel components from renewable oil. A fresh feedstock including saturated fatty acids is subjected to dilution by an organic lipophilic solvent. The solvent has a low phosphorus and metal impurity content, less than 5 ppm and less than 10 ppm, respectively. Dilution is performed before and/or during purification by at least one pretreatment process for removal of phosphorus and metal impurities. Subsequently, the resulting purified feedstock is fed into at least one post-treatment process suitable for producing liquid fuel components. | 04-11-2013 |

20080318423 | PROCESS FOR PRODUCING METAL OXIDE FILMS AT LOW TEMPERATURES - A process for producing metal oxide thin films on a substrate by the ALD method comprises the steps of bonding no more than about a molecular monolayer of a gaseous metal compound to a growth substrate, and converting the bonded metal compound to metal oxide. The bonded metal compound is converted to metal oxide by contacting it with a reactive vapour source of oxygen other than water, and the substrate is kept at a temperature of less than 190° C. during the growth process. By means of the invention it is possible to produce films of good quality at low temperatures. The dielectric thin films having a dense structure can be used for passivating surfaces that do not endure high temperatures. Such surfaces include, for example, organic films in integrated circuits and polymer films such as in organic electroluminescent displays and organic solar cells. Further, when a water-free oxygen source is used, surfaces that are sensitive to water can be passivated. | 12-25-2008 |

20120005788 | MANUFACTURE OF XYLONIC ACID - Provided is a method for producing xylonic acid from xylose with a recombinant fungal strain that is genetically modified to express a xylose dehydrogenase gene, which is able to convert xylose to xylonolactone, which is spontaneously or enzymatically hydrolysed to xylonic acid. The xylonic acid is excreted outside the host cell. Xylonate production may be coupled with xylitol production. Alternatively, if xylitol production is not desired, its production is reduced by removing the aldose reductase (or specific xylose reductase) enzyme, which converts xylose to xylitol. Expression of a heterologous lactonase encoding gene may result in higher acid concentrations. The method is suitable for producing xylonic acid from a hemicellulose hydrolysate such as hydrolysed lignocellulosic plant biomass. | 01-05-2012 |
20140045238 | Method for producing terpenes - The present invention relates to a method for producing terpenes in fungi, wherein a terpene biosynthetic gene cluster having terpene biosynthetic genes and regulatory regions operably linked to said genes is activated. The invention relates also to a terpene biosynthetic gene cluster and regulatory regions of such terpene biosynthetic gene cluster usable is production of terpenes, use of regulator for regulating the terpene production and use of | 02-13-2014 |
