| Paracin1.7 was a kind of bacteriocin which was extracted from Lactobacillus paracasei HD1.7 .Our research mainly studied stems HD1.7 regulated and controled metabolic Quorum-sensing mechanism Paracin1.7. We have examined antibacterial activity of stems HD1.7 under different growth conditions by Cylinder plate method, and by adjusting amount of Nutrition in culture medium we control cellular density in cultivation liquid. |

½ÓÉÏ Antibacterial activity of stems HD1.7 was closely linked to cellular density ,only when cellular density reach definite threshold(OD600=0.8£¬mycelia dried weight=0.3311g/L£©,stems showed antibacterial activity ;after signal molecule of different concentration , antibacterial activity of stems were influenced under different level ,and antibacterial activity of stems decreased apparently removing after removing signal molecule . |
