Screening of Probiotic Bacillus from Goats

XU Feng;ZHANG Huan-rong;XU Gui-li;ZHANG Xing-min;TANG Cheng;College of Life Science and Technology,Southwest University for Nationalities;  
In order to select super probiotic Bacillus strain,26 Bacillus strains isolated from goats were screened by Congo red staining method for cellulase production,filter paper enzyme activity and CMC enzyme activity of cellulase were further determined,biochemical acid resisting and bile salt resisting characteristics were studied.On this basis,the bacteriostatic and drug sensitivity of the strains were also determined.The results showed that 4 Bacillusstrains have better cellulase production characteristics than the other 22 Bacillus strains,one Bacillus subtilis strain was proved to be the best one to be used for probiotic strain with 4.4Ufilter paper enzyme activity,1610 UCMC enzyme activity was over 50%survival rate under the environment for pH 3.0and over 70%survival rate under the environment for 0.3% bile salt,this Bacillus subtilis strain had a significant antibacterial effect on Staphylococcus aureus,and sensitive to 16 kinds of commonly used antimicrobials.These results suggest that Bacillus subtilis X7F3 was a candidate of goat probiotics strain.
