Abstract:
The device enables the long time recording by controlling the recording time of image signal. The device comprises an input means (1), an image signal processing part (2), a recording head (REC-CH), a recording amplifier (AMP1), a capstan motor (10), a record control signal generating part for controlling the output state of the recording amplifier (AMP1) and a control part for controlling the capstan motor to rotate during the complex image signal is recorded.
Abstract:
The present invention relates to a method for screening genes used for increasing 1,4-butanediol (BDO) production by using proteomics data. In the present invention, 1,4-BDO productivity is increased when a Ncgl0630 (citrate synthase) protein and a Ncgl2145 (hypothetical protein) protein are overly expressed wherein the Ncgl0630 (citrate synthase) protein and the Ncgl2145 (hypothetical protein) protein are screened via the method which is used to find proteins related to 1,4-BDO productivity and accordingly increases productivity, thereby being widely applicable industrially.
Abstract:
The present invention relates to a strain that produces 4-hydroxybutyrate (4HB) wherein the activity of malate quinone oxidoreductase or phosphoenolpyruvate carboxykinase is reduced or removed; or introduces a polynucleotide that codes alpha-ketoglutarate synthase or mutants thereof, or pyruvate carboxykinase or mutants thereof, thereby improving the productivity of 4HB. Also, the strain has an additonally improved function of producing 4HB by introducing polynucleotide that codes pyruvate dehydrogenase and formate dehydrogenase. In the present invention, the transgenic strain in an anaerobic fermentation is used for producing 4HB in a high yield rate, thus being very useful in industrial application.
