| Abstract | ||
| Objective The aim of this study was to focus on exopolysaccharides (EPSs) produced by , or and their use as a prebiotic for , , or . Materials and methods Optimization of culture conditions using different carbon and nitrogen sources and different temperature, pH and incubation periods for maximum EPS production was studied. Results and conclusion It was found that the best conditions were as follows: the use of sucrose (20%) instead of glucose in MRS medium, incubation at pH 7.0 and temperature 37°C for 72 h incubation under anaerobic conditions to give the highest EPS yield; a yield of 13.99 g/l was recorded in case of when grown on the aforementioned optimized conditions. It was found that EPS has the highest prebiotic indices (I), varying from 7.9 to 10.1. In contrast, and EPSs have the lowest prebiotic indices (I), varying from 1.4 to 2.4. | ||
