The present invention relates to a method for producing medium chain diol and, more particularly to recombinant microorganisms in which fatty alcohol dehydrogenase and/or fatty alcohol oxidase genes on a &#x3c9;-oxidative metabolism pathway are deleted, the fatty aldehyde dehydrogenase genes are optionally deleted, and &#x3b2;-oxidative metabolism pathway-related genes are deleted, and to a method for producing medium chain diol from fatty acid-derived alcohol or alkane by culturing the recombinant microorganisms. The recombinant microorganisms of the present invention can produce a high yield of medium chain diol by preventing further oxidation and &#x3b2;-oxidative metabolism of fatty alcohols.

Method for producing medium chain diol

The present invention relates to a method for preparing a recombinant microorganism simultaneously comprising genes encoding enzymes used in the biosynthesis pathway of 6-aminocaproic acid, which is a precursor of caprolactam, biosynthesizing 6-aminocaproic acid from the microorganism, and producing the same so as to synthesize caprolactam.

Biological synthesis of 6-aminocaproic acid and transgenic microorganism therefor

The present invention relates to a new gene fragment derived from Chinese hamster ovary (CHO) cell for enhancement of recombinant protein expression in animal cells and a use thereof. It has been found that using the vector comprising a gene fragment of the present invention enhances the expression of a target protein in animal cells. Accordingly, the vector comprising a gene fragment of the present invention could be usefully used in the production of biopharmaceuticals such as therapeutic antibodies, etc.

Vector comprising gene fragment for enhancement of recombinant protein expression and use thereof

A method and apparatus for measuring the synthetic reception pattern of an adaptive array antenna, which are divided into a hardware apparatus and a measurement method. The hardware apparatus includes a wavefront simulator, a GNSS simulator, an external controller, a signal measurement unit, and a GNSS receiver. The measurement method using the hardware apparatus includes setting a direction of arrival of jamming and calculating a weight vector, fixing weight vectors at the calculated weight vector and collecting outputs of an array antenna system for all test signals, and displaying the collected data on a grid of a 2D plane. In accordance with the present invention, a weight vector calculated under a specific jamming situation is maintained for all test signals, so that the synthetic reception pattern of the array antenna system can be measured.
