| 摘 要： | 合适的发酵条件能够有效地提高嗜酸乳杆菌La-1细菌素的产量。在已经确定碳源、氮源和复合维生素的基础上,采用正交试验的方法研究了以MRS为基础的发酵培养基中各营养成分的相互协同作用,10L发酵罐试验证实,优化后的培养基和各项优化技术参数能使细菌总数提高了53.6%,细菌素抗菌活性提高了35.3%,抑菌圈达到了25mm以上。

| Abstract: | Fermentation conditions are able to effectively improve the production of Lactobacillus acidophilus La-1 bacteriocin.First of all,the content of the carbon,nitrogen and multi-vitamin in this study were established,Then,the optimal nutrient composition in the MRS were also established by the orthogonal test method.Finally,10L fermentor experiment confirmed that the total number of bacteria have been increased 53.6% after optimization of the medium and the optimization of technical parameters,At the time,bact... |
