| Abstract: | Objective： To investigate the security of lactobacillus acidophilus LB10.16 and bacillus subtilis BS7.29,in order to provide the technical support for the application.Method： Test methods including mice irrigation suits,acute attack poison,intraperi-toneal injection and mice biggest tolerance dose,acute attack toxicity test were applied to investigate the security of bacillus subtilis BS7.29 and lactobacillus acidophilus LB10.16.Results： The small intestinal vermiculation and intestinal peristalsis could be promote obviously by LB10.16 at 1×108 cfu/kg.bw or BS7.29 at 5×108 cfu/kg.bw.Conclusion： The two strains were nontoxic substances,and the security of which was well. |
