Abstract
Microbial exopolysaccharides (EPSs) are currently under intensive research in various applications. However, studies on EPS from Bacillus velezensis are rare and the emulsifying properties of this EPS have not been studied previously. An EPS produced by a novel B. velezensis BABA50 strain isolated from an Algerian hot spring was characterised. The results of structural, morphological and thermal analyses showed a heteropolymeric structure containing galactose, glucose, glucuronic acid and N-acetyl glucosamine. Analyses revealed the presence of carbonyl and hydroxyl groups, branched and highly porous structure and relevant thermal stability compared to other EPSs with a high degradation temperature of 260 °C and 38% of residual mass at 800 °C. EPS from B. velezensis BABA50 presents distinct polymer in terms of structure and composition compared to previously described EPS with excellent emulsifying and antioxidant activities; this EPS holds great potential in the food and cosmetic industries as a thermostable emulsifier and antioxidant agent.
