Abstract
- The agro-industrial byproducts from the industries for the Sikhye, traditional Korean food production (AIB-I), the apple juice production (AIB-II), and the soy sauce production (AIB-III) were examined as the substrate for the production of the heteropolysaccharide (PS-7) by B. indica HS2001. Major components of AIB-I are dextrin, maltotriose, and maltose. Major ones of AIB-II and AIB-II were carbohydrate and protein, respectively. Dextrin and AIB-II were found to be better carbon sources than glucose for the production of PS-7. Conversion rates of PS-7s from 2% (w/v) dextrin and 2% (w/v) AIB-II as the carbon source were 20%. As concentration of agro-industrial byproducts as the carbon source increased, cell growth and the production of PS-7 increased whereas conversion rates of PS-7s decreased. The monomeric components of PS-7s produced by B. indica HS2001 with agro-industrial byproducts as the carbon source were identified to be glucose and rhamnose and their molar ratios of rhamnose to glucose were all in the range of 1.0 to 4.5∼4.7. It seems that B. indica HS2001 utilized all the agro-industrial byproducts used in this study and produced PS-7s with the same composition as well as the same molar ratio of their monomeric component.
