一种乳酸菌食品级表达载体pMG36N及其制备方法
摘要：
本发明公开了一种乳酸菌食品级表达载体pMG36N。该乳酸菌食品级表达载体不含红霉素抗性基因，并引入了天然食品防腐剂乳链菌肽Nisin抗性基因nisI，以此作为选择标记。本发明还公开了上述乳酸菌食品级表达载体pMG36N的制备方法。本发明乳酸菌食品级表达载体pMG36N不以红霉素等抗性基因作为筛选标记，提高了乳酸菌的安全性，可以用于食品生产。
摘要（英）：

The invention discloses a lactobacillus food grade expression vector pMG36N which does not contain erythrocin resistance gene, introduces a natural food preservative streptococcus lactis peptide Nisinresistance gene nisI as a selection mark. The invention also discloses a preparation method of the lactobacillus food grade expression vector pMG36N. The lactobacillus food grade expression vector pMG36N does not take the resistance gene, i.e. erythrocin and the like, as a screening mark, enhances the safety of lactobacillus and can be used for food production.
