چکیده انگلیسی
A new strain bacteria was isolated and named as Phyllobacterium sp. 921F, due to its high production capacity of exopolysaccharide (EPS). Characterization of physico-chemical properties of the EPS and optimization for high production were conducted to aim at industrial applications. The optimum pH and temperature were 7.0 and 30 °C, respectively. The following scale-up fermentation was carried out in 30 L bioreactor and amounts of EPS (21.9 g/L) were produced. The EPS with a molecular mass of 1082 kDa was composed of glucose, galactose, and pyruvate. The EPS solution behaved as Newtonian at low concentrations (â¤0.3%) and as shear thinning at higher concentration (e.g, 1%). The moisture retention ability of the EPS was found to be superior to hyaluronic acid. Results suggest that Phyllobacterium sp. 921F is a good candidate for large-scale production of the EPS which might be utilized in food and cosmetics industries.
