Abstract
A method for screening Lactobacillus casei fermentation agent is provided. The method is specifically implemented by screening a Lactobacillus casei strain with high-expression of a lac cluster gene and no enzymatic activity of β-fructosidase. The Lactobacillus casei strain that rapidly metabolizes lactose is screened through high expression of the lac cluster gene, such that the problem of large differences in acid production in fermented milk beverage products is avoided.
