Notice of Retraction: Effect of Steroidal Saponins from Fructus Tribuli on Growth of Lactobacillus casei and Lactobacillus reuteri

Abstract

Effect of steroidal saponins from Fructus tribuli on growth of Lactobacillus reuteri and Lactobacillus casei was studied by measuring optical density at 600nm and pH using MRS media as the control. The addition of steroidal saponins (w/v) was 0.05%, 0.10%, 0.15%, 0.20% and 0.25% Results were as follows: addition of steroidal saponins could promote the growth of Lactobacillus reuteri and Lactobacillus casei. The optimum concentration of steroidal saponins in MRS media was 0.025% at incubation 18h for Lactobacillus reuteri and 0.25% at incubation 24h for Lactobacillus casei.
