Composition for promoting the proliferation of lactobacillus casei subsp. casei

Abstract

The present invention relates to a composition for promoting bacterial proliferation for selectively proliferating Lactobacillus casei subsp. casei , which includes a dextran. According to the present invention, a variety of biological activities originated from L. casei subsp. casei can be sustained in a living body by selectively growing-proliferating and colonizing L. casei subsp. casei in the intestine of a human being, animal, or the like or by selectively growing-proliferating L. casei subsp. casei in the intestine, without supplying L. casei subsp. casei at all times.

1 . A composition for promoting bacterial proliferation for selectively proliferating  Lactobacillus casei  subsp.  casei , comprising a dextran.  
   
   
       2 . The composition for promoting bacterial proliferation according to  claim 1 , further comprising  Lactobacillus casei  subsp.  casei.    
   
   
       3 . The composition for promoting bacterial proliferation according to  claim 1 , wherein the dextran has a molecular weight of 2,000 to 40,000,000.  
   
   
       4 . A pharmaceutical composition comprising the composition for promoting bacterial proliferation according to  claim 2 .  
   
   
       5 . A health food comprising the composition for promoting bacterial proliferation according to  claim 2 .  
   
   
       6 . A feed comprising the composition for promoting bacterial proliferation according to  claim 2.
