Abstract:
A method for monitoring and detecting a target strain is provided to maintain segregational stability by injecting a gene of a selection marker into chromosome DNA of a host cell and selectively detect the target strain from the same strains when the same strains are mix-cultivated using a transposon system. A method for monitoring and detecting a target strain comprises the following steps of: introducing a gene which can work as a selection marker in a genome of the target strain using a transposon system; and detecting and monitoring the target strain using the selection marker. The transposon system consists of a DNA fragment and transposase.

Abstract:
A method for disrupting a target gene based on cloning through restriction enzyme cutting is provided to show improved accuracy, convenience and increased transformation efficiency compared to conventional methods, thereby being useful for genetic engineering and bio-industries. In the method for disrupting a target gene by inserting a nucleotide sequence fragment(c) which includes a nucleotide sequence fragment(a) located at the upper portion of 5' terminal at an open leading frame starting point of the target frame, and a nucleotide sequence fragment(b) from an open leading frame starting point of a selective marker to a certain point of the inside of the open leading frame starting point of the selective marker in sequence from the 5' terminal side; and a nucleotide fragment(f) which includes a nucleotide sequence fragment(d) from the starting point formed to have an overlapped portion with the nucleotide sequence fragment(b) to an open leading frame ending point of the selective marker and a nucleotide sequence fragment(e) located at the lower portion of 3' terminal at the open leading frame ending point of the target gene in sequence from the 5' terminal side into a host, the nucleotide sequence fragment(c) is obtained from the nucleotide sequence fragment(a) inserted via a restriction enzyme site and a vector(A) including all gene sequence of the selective marker and the nucleotide sequence fragment(f) is obtained from the all gene sequence of the selective marker and a vector(B) including the nucleotide sequence fragment(e) inserted via the restriction enzyme site.
Abstract:
PURPOSE: A telephone for an aged person is provided to alternatively output ring tone of frequency band suitable to auditory characteristic of each user, thereby easily confirming a call alarm. CONSTITUTION: A ring tone output unit(30) alternatively outputs ring tone of at least two kinds of frequency bands. A ring tone control unit(40) controls a ring tone output unit. The main control unit(70) applies a control signal to the ring tone control unit, based on an input signal through a transceiver unit(14). The ring tone of at least 2 kinds of frequency bands is a ring tone of low frequency band suitable to auditory characteristic of an aged person and high frequency band suitable to auditory characteristic of a general person.
Abstract:
PURPOSE: A manufacturing method of composition for smell elimination of Oncorhynchus masou and a steak manufacturing method using the same method are provided to maintain flesh and taste of the Oncorhynchus masou while removing fishy smell of the Oncorhynchus masou. CONSTITUTION: A manufacturing method of composition for smell elimination of Oncorhynchus masou includes the following steps: manufacturing a compound by adding water 67.5-83.5 weight%, dried Polygonati Rhizoma 2.5-6.5 weight%, dried Schizandrae Fructus 0.8-1.8 weight%, dried Lycii Fructus 0.7-1.7 weight%, glycyrrhizae radix 2-4 weight%, alive lotus root 8-15 weight%, garlic 1.1-2.5 weight%, and ginger 0.7-1.7 weight%; heating the compound for 30 ~ 180 minutes; filtering and cooling the compounds in 3-10°C and adding red wind on the heated compound.
Abstract:
PURPOSE: Provided are a method of quantitatively and qualitatively analyzing lactic acid bacteria and a PCR primer which is capable of quantitatively and qualitatively analyzing lactic acid bacteria present in fermented foods. The quantitative and qualitative analysis can be carried out by performing QC-PCR with a PlaF/PlaR primer and an MesF/MesR primer to determine the fermentation degree and aging degree of fermented foods, and the storage state and quality thereof. CONSTITUTION: A method for quantitatively analyzing lactic acid bacteria comprises the step of: adding a target DNA to a sample and mixing a competitor Cmes or Cpla and performing PCR with a specific primer set of Lactobacillus plantarum or a specific primer set of Leuconostoc mesenteroides; measuring PCR amplification of the competitor and target DNA; and calculating the concentration of the target DNA concentration from the PCR amplification rate and the concentration of the competitor.
