摘要：
The strain RL22P isolated from infant faeces was identified using genus-specific polymerase chain reaction (PCR), species-specific PCRs and 16S rDNA gene sequencing as Lactobacillus gasseri. The strain RL22P was tested for the production of antimicrobial substances using agar-spot test and agar-diffusion test. The strain produced antimicrobial substances (organic acids, hydrogen peroxide and proteinaceous substances) against fifteen indicator strains. The most effective was against Lactobacillus and Clostridium indicator strains. Antimicrobial proteinaceous substances produced only against six Lactobacillus strains.
