    摘要: A method for characterizing a subsurface formation includes receiving image data of the subsurface formation obtained by a sensor tool and receiving a plurality of non-image data logs, each non-image data log being obtained by a different type of sensor tool. The method also includes performing an electrofacies analysis on the plurality of non-image data logs where the electrofacies analysis includes defining clusters wherein each cluster has a similar property to provide a plurality of electrofacies blocks with each electrofacies block representing a depth interval. The method further includes partitioning the image data into multiple high-resolution depth segments that share a similar property, feature, and/or pattern for each electrofacies block and assigning data from the plurality of non-image data logs into a corresponding high-resolution depth segment to provide a high-resolution data log that characterizes the subsurface formation.

    摘要: Disclosed is linoleic acid isomerases and their application in production of conjugated linoleic acid, which belongs to the technical fields of protein engineering and microbial engineering. The linoleic acid isomerase derived from Bifidobacterium is used to produce the conjugated linoleic acid. The recombinant E. coli containing the linoleic acid isomerase of the invention is added into a reaction system containing linoleic acid and react for 3 h to produce conjugated linoleic acids. The conversion rate of the conjugated linoleic acid of the invented method ranges from 12.1% to 42.1%, and the percentage of cis9, trans11-CLA in the conjugated linoleic acid can reach 84.3% to 89.1%. The invention provides a method for using microorganisms to produce conjugated linoleic acids with high safety and yield where cis9, trans11-CLA isomer is the major form in the conjugated linoleic acid products.

    摘要: Disclosed is a diacylglycerol acyltransferase 1, a recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1, and application thereof in production of triacylglycerol. The diacylglycerol acyltransferase 1 of the invention has a function of catalyzing synthesis of triacylglycerol. After the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 of the invention is subjected to induction culture for 48 h, the content of total fatty acid and triacylglycerol in the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 can be respectively increased by 1.94 folds and 12.09 folds as compared with those of Saccharomyces cerevisiae without the recombinant diacylglycerol acyltransferase 1. The instant invention provides a method for improving the ability of microorganisms to produce polyunsaturated fatty acids (PUFAs) by means of genetic engineering.
