摘要:
A heater integrated gas chromatography (GC) column device according to the present invention is capable of precisely and uniformly controlling a temperature by having a high thermal conductivity, and raising and lowering a temperature at a high speed by having a low thermal mass, such that a measuring time is significantly decreased. The GC column is in contact with a bobbin with a homogeneous temperature distribution, and thus a temperature is homogeneously distributed in each GC column. Further, the heater integrated GC column device according to the present invention has the above-described effects and may have a smaller size.

摘要:
The present invention relates to a lactic acid bacterium isolated from human mother's milk, more precisely a Lactobacillus gasseri BNR17 strain that is isolated from Korean mother's milk and has excellent probiotic activity including acid resistance, bile acid resistance and antimicrobial activity and weight gaining inhibitory effect as well. Again, the Lactobacillus gasseri BNR17 of the present invention has excellent acid resistance, bile acid resistance, enteric absorption activity and antimicrobial activity against pathogenic microorganisms, in addition to the weight gaining inhibitory effect by synthesizing indigestible polysaccharides from monosaccharides included in food taken and releasing the synthesized polysaccharides out of the body. Therefore, the strain of the invention, owing to such beneficiary effects, can be effectively used not only for the production of fermented milk, other fermented food products and animal feeds but also for the production of live cell products and food additives for preventing weight gaining.
