Bacillus polyfermenticus SCD which is commonly called as 'Bispan strain' has been appropriately used for the treatment of long-term intestinal disorders, since the live strains in the form of active endospores can successfully reach the target intestine. The goal of this study were to get the novel bispan mutant strain and to get higher spore number of bispan mutant in submerged fermentation. Bispan mutant KD21 was obtained using NTG mutagenesis of bispan strain, and bispan mutant was cultivated in 5 L jar fermenter. In this study, productivity and sporulation rate of the bispan mutant KD2l showed approximately 77% increase when compared with bispan strain.

Beneficial bacteria, which have been used for medical purpose and for medicines for treating intestinal disorders, include strains of Bifidobacterium sp., Lactobacillus sp., Enterococcus sp., Clostridium butyricum, Lactobacillus sporogenes, Bacillus subtilis, Bacillus polyfermenticus and the like. Bacillus polyfermenticuss SCD with is commonly called as Bispan strain has been appropriately used for the treatment of long-term intestinal disorders, since the live strains in the form of active endospores can successfully reach the target intestine. In this study, the identification and characterization of Bispan strain was done using SEM observation, API 50CHB kits, isoprenoid quinone analysis, and fatty acid analysis. These results suggest that Bispan strain is very similar to Bacillus subtilis.

Bacillus polyfermenticus KJS-2 (Bp2) was isolated from $Bispan^{(R)}$, a commercially available probiotics consisting of more than 4 strains. The objective of this study was to investigate the effect of three-layer coating on the stabilty of Bp2. Bp2 was microencapsulated with sodium alginate using an air atomizer. The Bp2 loaded pellets were also coated with HFP-chitosan and HPMCP for oral delivery system. When compared to the uncoated Bp2, the survival of the three-layer coated Bp2 increased to approximately 63% (p<0.01) in a 30% ethanol solution, 54% (p<0.05) in an artificial gastric juice (pH 2), and 53% (p<0.05) in the bile acid (pH 5). When coated beads were stored at $100^{\circ}C$ and $130^{\circ}C$, Bp2 in coated beads was very stable (p<0.01) compared to uncoated Bp2.
