| Abstract | This work aimed to study the effect of riceberry broken rice and soybean meal on exopolysaccharide (EPS) production by Bacillus tequilensis PS21. Various concentrations of riceberry broken rice (RBR) as carbon source at 4, 5, and 6%, soybean meal (SBM) as nitrogen source at 1, 2, and 3% were used whilst the fermentation conditions at 37 ?C and media pH 7 were constant. The results showed that as fermentation time increased from 24, 48 to 72 h, the EPS content increased significantly along with bacterial growth. RBR (4, 5, and 6%) at 72 h resulted in no significant differences in EPS production. However, SBM at 1, 2, and 3% resulted in a statistically significant difference in EPS content at 72 h. Therefore, the optimized conditions for EPS production were RBR at 5% and SBM at 3% for an EPS content of 28.47 g/L. This work demonstrated a new way to add value to RBR and SBM to produce an EPS bioproduct for future applications including foods, cosmetics, and animal feeds. |
