一种高产赖氨酸的枯草芽孢杆菌PL83及制备方法和应用
摘要：
本发明公开了一种高产赖氨酸的枯草芽孢杆菌PL83及制备方法和应用，从猪肠道中采取食糜，筛选枯草芽孢杆菌，然后通过紫外照射，AEC筛选，获得了一株高产赖氨酸的枯草芽孢杆菌(Bacillus subtilis)PL83，CCTCC NO：M2013412。10L发酵罐用LB培养基进行发酵，赖氨酸的产量为30-40g/L，枯草芽孢杆菌（Bacillus subtilis）PL83结合芽孢杆菌的抗菌活性和高产赖氨酸的能力，具备增强免疫、促生长的功能，可以显著抑制致病菌的生长繁殖、增强动物免疫能力，对动物生长和健康具有促进的作用。
摘要（英）：

The invention discloses high-lysine yield bacillus subtilis PL83, a preparation method and application. The high-lysine yield bacillus subtilis PL83 which has a preservation number of CCTCC NO:M2013412 is obtained by steps of collecting chyme from intestinal tracts of pigs, screening bacillus subtilis and performing ultraviolet irradiation and AEC screening. An LB (Luria-Bertani) culture medium is used for fermentation in a 10L fermentation tank. The yield of lysine is 30 to 40g/L. In combination of antibacterial activity and high lysine production capability of bacillus, the bacillus subtilis PL83 has immunity enhancement and growth promotion effects, so that the growth and reproduction of pathogenic bacteria can be remarkably suppressed, the immunity of an animal can be enhanced, and an effect of promoting the growth and health of the animal is achieved.
