Abstract: The effects of lactoferrin and lactoferricin on Lactobacillus acidophilus growth were studied in this paper. The results showed that the growth of Lactobacillus acidophilus was promoted when certain concentration of lactoferrin or lactoferricin was added to culture medium and cultured at 37 ℃. The optimal concentration of lactoferrin and lactoferricin were 2.5 mg/ml and 0.15 mg/ml, respectively. After cultured 26 h, the colony forming units were 6.7×108 CFU/ml and 8.0×108 CFU/ml, respectively.

Key words: lactoferrin, lactoferricin, Lactobacillus acidophilus
