| 摘 要： | 通过对本实验室选育所得的乳链菌肽高产菌株的发酵条件进行研究，得出了最佳发酵条件。该菌的最佳碳源为蔗糖，最佳氮源为大豆蛋白胨，二者浓度都为１％。浓度为１５０ｍｍｏｌ／Ｌ以下的Ｎａ２ＨＰＯ４·１２Ｈ２Ｏ对发酵有促进作用，３０℃为最适温度。

| Abstract: | The fermentation conditions of the nisin high yield strain L. lactis Y-72 is screenedin our labratory. We find that the optimum carbon source and nitrogen source are 1 % sucrose and1 % soy peptone, respectively. The addition of other nitrogen sources has positive effect and aphosphate source under the level of 150 mmol/L is also benefit to produce nisin. |
