摘要

弗氏丙酸杆菌rv -4-irf是一种产生抗菌素代谢产物的益生菌，适用于食品保护。除低分子丙酸酯外，在有和不含色氨酸的培养基中观察到抗菌因子的产生。开发了一种从培养液中生产高分子量外聚物的方法。利用蛋白酶k对其多肽性质进行了验证。从弗氏假单胞菌rvs -4-irf中制备的胞外多肽具有抑制真菌和细菌生长的物种特异性活性。

[Production of Antimicrobial Polypeptides by Propionibacterium freudenreichii RVS-4-irf].

Propionibacterium freudenreichii RVS-4-irf is a probiotic bacterium producing antimicrobial exometabolites applicable for foodstuff protection. Production of antimicrobial factors other than lowmolecular propionates was observed in media with and without trypton. A method was developed for production of the fraction of high-molecular mass exopolymers from the culture liquid. Their polypeptide nature was confirmed using proteinase K. The preparation of extracellular polypeptides from P. freudenreichii RVS-4-irf exhibited species-specific activity in suppression of fungal and bacterial growth.
