Abstract:
An aspect of the present invention relates to Pdh with an increased activity under an anaerobic condition, and a microorganism including the same. If the Pdh activity increases under the anaerobic condition, an acetyl-CoA metabolism process can be compelled. Accordingly, a compound can be produced by using metabolism products of a TCA cycle. Furthermore, the microorganism produced thereby can increase the production amount of 1,4-BDO under the anaerobic condition. The method can be applied to various microorganisms used in a fermentation process. The method contributes to the yield improvement of the fermentation process, thereby being usefully used in industry.
Abstract:
PURPOSE: An apparatus and a method for a digital phase locked loop in a wireless communication system are provided to apply digital PLL(Phase Loop Lock) having high performance to a small communication device by reducing power consumption and an occupied area of PLL. CONSTITUTION: A DCO(Digitally Controlled Oscillator)(102) receives a digital tuning word from a digital loop filter(116). The DCO generates a signal of a frequency corresponding to the digital tuning word. An N-divider(104) divides the frequency signal outputted from the DCO to an integer ratio. A PFD(Phase Frequency Detector)(106) outputs an up signal or a down signal by receiving a divided signal and a reference frequency. An XOR operator performs XOR calculation of the up signal and the down signal outputted from the PFD. A TDC(Time to Digital Convertor)(110) changes a time difference value, which is shown in the up signal and the down signal calculated by an XOR operation, into a digital code. A delay comparator(112) compares two consecutive digital codes provided from the TDC. A level scalar(114) adds codes for channel switching according to channel selection information.

Abstract:
Provided are a novel promoter of Corynebacterium glutamicum; a vector including the promoter; a host cell having the vector; and a method to express gene using the host cell. When comparing and analyzing the expression of the promoter with a conventional gapA promoter, high expression level is maintained not only under an aerobic condition but an anaerobic condition. Construction of a system which can overexpress desired genes in the Corynebacterium glutamicum using the promoter can be possible.
Abstract:
PURPOSE: A deformed microorganism for production of 1,4-butanediol is provided to produce 1,4-BDO by a biological producing process. CONSTITUTION: A deformed microorganism for production of 1.4-butanediol comprises: an activation converting alpha-ketoglutarate or succinate into 4-hydroxybutyril-CoA ("4-HB-CoA"); and an activation converting the 4-HB-CoA into 1,4-butanediols ("1,4-BDO"). The activation converting the 4-HB-CoA into the 1,4-BDO is coded by more than one kind of genes selected from a group comprising adh1, yiaY, adh4, adhB, mdh, eutG, fucO, dhaT, aldA, eutE, adhE1, adhE2 and adh2.
Abstract:
A parallel processing apparatus and a method thereof are provided to produce a working division control block dynamically in case a plurality of tasks are parallel-processed by multiple threads. A parallel processing apparatus(100) comprises the followings: a container part; a controller(140) determining whether access to a control block, included in the first container which exists in the direction in which task by at least one thread progresses, is possible or not; a container generating unit(160) which produces the second container in which at least one control block is included according to the determined result; and a container managing unit(150) which is connected with the control block in a ring type.
