| Paracin1.7是從副干酪乳桿菌（Lactobacillus paracasei）HD1.7發(fā)酵液中提取的一種細(xì)菌素，本文主要研究菌株HD1.7在發(fā)酵過程中調(diào)控Paracin1.7代謝的群體感應(yīng)機(jī)制。利用杯碟法檢測不同生長條件下菌株HD1.7 的抑菌活性，通過調(diào)整培養(yǎng)基營養(yǎng)成分的多寡，控制培養(yǎng)液中細(xì)胞密度。菌株HD1.7的抑菌活性與其細(xì)胞密度密切相關(guān), 只有當(dāng)細(xì)胞密度達(dá)到一定的閾值(OD600=0.8，菌體干重為0.3311g/L）時, 菌株才能表現(xiàn)抑菌活性; 當(dāng)添加不同濃度的信號分子后，菌株抑菌活性受到不同程度的影響，并且在去除信號分子后，菌株的抑菌活性明顯降低。Paracin1.7是存在于HD1.7發(fā)酵液中的特殊的群體感應(yīng)信號分子，可進(jìn)行自我誘導(dǎo)。Paracin1.7的抑菌活性受到HD1.7群體感應(yīng)系統(tǒng)的調(diào)控。 |

| 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. |

接上 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 . |

第一句中有句話翻錯了Our research mainly studied stems HD1.7 regulated and controled metabolic Quorum-sensing mechanism Paracin1.7。改成Our research mainly studied stems HD1.7 regulated and controled metabolic Quorum-sensing mechanism of Paracin1.7 in the process of fermentation. 最后一句翻譯 Paracin1.7 was specially Quorum-sensing signal molecule that exited in HD1.7 fermentation liquor and could make self induction. antibacterial activity of Paracin1.7 was regulated and controlled by Quorum-sensing system of HD1.7 . |
