11株枯草芽孢杆菌益生特性研究
Study on Probiotic Characteristics of Eleven Bacillus subtilis Strains
摘要
Abstract
The purpose of this study was to investigate the property of antibacterial,production of enzymes,tolerance and in vitro digestibility of 11 Bacillus subtilis strains.9 Bacillus subtilis strains were screened out according to antibacterial property and production of enzymes.After tests of heat,pH tolerance,artificial gastrointestinal fluid and pig bile salt,6 Bacillus subtilis strains had good performance in simulation of animal digestive tract and strong heat tolerance in the process of production.Meanwhile,5 strains BLCC1-1,BLCC1-2,BLCC1-3,BLCC1-4 and BLCC1-6 had good digestion effects on different combinations of feeds.Based on the above results,it suggested that BLCC1-1,BLCC1-2,BLCC1-4 and BLCC1-6 had excellent production of enzymes,tolerance and in vitro digestibility,which might be suitable for using as feed additives and further research.关键词
