植物乳杆菌的生理特性及影响其增殖的因素

Physiological Characteristics and Factors of Proliferation on Lactobacillus plantarum

植物乳杆菌作为一类有益菌,在人类生产生活中应用广泛。在其生长繁殖过程中会产生具有抑菌效果、调节免疫功能的代谢产物,在一定程度上可起到类抗生素的作用。碳源、氮源是植物乳杆菌生长过程中的必需营养物质,主导菌体细胞壁的形成和代谢物质的合成。适宜的温度、pH及接种量等发酵条件对菌体繁殖速度和生产效益发挥关键作用。本文对影响植物乳杆菌增殖的底物和条件进行综述,以期为增加生产效率、提高生产效益奠定基础。

As a sort of probiotic,Lactobacillus plantarum was widely used in human production activity,metabolites with the antibacterial effects and immunomodulatory produced in the growth works as well as antibiotics.Carbon source and nitrogen source are essential culture medium,which dominate the generation of cell and synthesis of metabolic substance.Proper temperature,pH,bacterial load and so on play a key role in multiplicative process and performance.The mediumand fermentation conditions of cultivate Lactobacillus plantarum are reviewed,which would lay a foundation for increasing production efficiency and enhancing benefit.
