Characterization of Bacillus polyfermenticus SCD for Oral Bacteriotherapy of Gastrointestinal Disorders

식품용 프로바이오틱 비스루트균의 주요 생균제 특성

  • Published : 2002.02.01


Bacillus polyfermenticus SCD, which is commonly called as Bisroot strain, is being used for functional foods through the treatment of long-term intestinal disorders, since the live strains in the form of active endospores can successfully reach the target intestine in both humans and animals. The cells of B. polyfermenticus SCD were treated for 24 h in artifical bile after incubation for 2 h in artificial gastric juice and final number of the strain was reached to around $3.3{times}10^7\;CFU/mL$. In test of API ZYM kit, ${\beta}-glucuronidase$ or ${\beta}-glucosidase$ was not produced by B. polyfermenticus SCD. B. polyfermenticus SCD was resistant to antibiotics, such as nisin, streptomycin, tetracycline, and rifamycin. B. polyfermenticus SCD was also affected by alcohol concentration up to 4%, but more than 8%, their growth was not affected significantly. Finally, B. polyfermenticus SCD was shown to inhibit the growth of Listeria monocytogenes ATCC 19111 completely within 24 h of incubation, which indicated its bactericidal nature.
