Abstract

Bacillus polyfermenticus SCD derived from Bacillus sp., which is commonly called as Bisroot$^{ⓡ}$. The goal of this study, is to Increase stability of Bacillus polyfermenticus SCD in low pH, high temperature and high glucose concentration via three layer coating. The viability of coated Bacillus polyfermenticus SCD increased to 30%, 20%, 14% in the condition of pH 2 4 6 than that of uncoated Bacillus polyfermenticus SCD at 37$^{\circ}C$ for 4 h. Final viability of the coated Bacillus polyfermenticus SCD in 80$^{\circ}C$ increased to 40% than that of uncoated Bacillus polyfermenticus SCD. In high glucose concentration coated Bacillus polyfermenticus SCD is more stable than uncoated about 50%. In conclusion, the three layer coated Bacillus polyfermenticus SCD is very stable for low pH, high temperature and high glucose concentration.
