The influence of initial pH of sugar cane juice in high concentration was investigated for levan production by Zymomonas mobilis. In the initial pH of medium of 5.4; 5.9 and 6..3 the levan concentration achieved 1.66; 2.54 and 3.83 g/L, respectively, in 48 hours of fermentation. The final levan concentration in the initial pH of 6.3 and 5.9 increased 130 and 53% when compared to concentration at initial pH 5.4 in the medium. The levan yield at pH 5.9 was 87.5% and at pH 6.3 was 162.5% superior in relation to that obtained at initial pH 5.4.
