Effect of CO2 concentration on the growth and exopolysaccharide production of Bifidobacterium longum cultivated under anaerobic conditions.
For substantial cell growth and exopolysaccharide (EPS) production of Bifidobacterium longum JBL05, anaerobic conditions (dissolved oxygen concentrations below 0.05 ppm) and the supplement of CO2 (> or = 20%) were required. Under these conditions, B. longum JBL05 produced EPS amounts of up to 2.9 g/l.
